      iov_iter: saner helper for page array allocation · 3cf42da3
      Al Viro authored
      All call sites of get_pages_array() are essenitally identical now.
      Replace with common helper...
      
      Returns number of slots available in resulting array or 0 on OOM;
      it's up to the caller to make sure it doesn't ask to zero-entry
      array (i.e. neither maxpages nor size are allowed to be zero).

      fold __pipe_get_pages() into pipe_get_pages() · 85200084

      ... and don't mangle maxsize there - turn the loop into counting
      one instead.  Easier to see that we won't run out of array that
      way.  Note that special treatment of the partial buffer in that
      thing is an artifact of the non-advancing semantics of
      iov_iter_get_pages() - if not for that, it would be append_pipe(),
      same as the body of the loop that follows it.  IOW, once we make
      iov_iter_get_pages() advancing, the whole thing will turn into
      	calculate how many pages do we want
      	allocate an array (if needed)
      	call append_pipe() that many times.

      	The differences between those two are
      * pipe_get_pages() gets a non-NULL struct page ** value pointing to
      preallocated array + array size.
      * pipe_get_pages_alloc() gets an address of struct page ** variable that
      contains NULL, allocates the array and (on success) stores its address in
      that variable.
      
      	Not hard to combine - always pass struct page ***, have

      ITER_PIPE: cache the type of last buffer · 10f525a8
      Al Viro authored
      We often need to find whether the last buffer is anon or not, and
      currently it's rather clumsy:
      	check if ->iov_offset is non-zero (i.e. that pipe is not empty)
      	if so, get the corresponding pipe_buffer and check its ->ops
      	if it's &default_pipe_buf_ops, we have an anon buffer.
      
      Let's replace the use of ->iov_offset (which is nowhere near similar to
      its role for other flavours) with signed field (->last_offset), with
      the following rules:
      	empty, no buffers occupied:		0
      	anon, with bytes up to N-1 filled:	N
      	zero-copy, with bytes up to N-1 filled:	-N
      
      That way abs(i->last_offset) is equal to what used to be in i->iov_offset
      and empty vs. anon vs. zero-copy can be distinguished by the sign of
      i->last_offset.
      
      	Checks for "should we extend the last buffer or should we start
      a new one?" become easier to follow that way.
      
      	Note that most of the operations can only be done in a sane
      state - i.e. when the pipe has nothing past the current position of
      iterator.  About the only thing that could be done outside of that
      state is iov_iter_advance(), which transitions to the sane state by
      truncating the pipe.  There are only two cases where we leave the
      sane state:
      	1) iov_iter_get_pages()/iov_iter_get_pages_alloc().  Will be
      dealt with later, when we make get_pages advancing - the callers are
      actually happier that way.
      	2) iov_iter copied, then something is put into the copy.  Since
      they share the underlying pipe, the original gets behind.  When we
      decide that we are done with the copy (original is not usable until then)
      we advance the original.  direct_io used to be done that way; nowadays
      it operates on the original and we do iov_iter_revert() to discard
      the excessive data.  At the moment there's nothing in the kernel that
      could do that to ITER_PIPE iterators, so this reason for insane state
      is theoretical right now.

      ITER_PIPE: allocate buffers as we go in copy-to-pipe primitives · 8fad7767
      Al Viro authored
      New helper: append_pipe().  Extends the last buffer if possible,
      allocates a new one otherwise.  Returns page and offset in it
      on success, NULL on failure.  iov_iter is advanced past the
      data we've got.
      
      Use that instead of push_pipe() in copy-to-pipe primitives;
      they get simpler that way.  Handling of short copy (in "mc" one)
      is done simply by iov_iter_revert() - iov_iter is in consistent
      state after that one, so we can use that.

      ITER_PIPE: helpers for adding pipe buffers · 47b7fcae
      Al Viro authored
      There are only two kinds of pipe_buffer in the area used by ITER_PIPE.
      
      1) anonymous - copy_to_iter() et.al. end up creating those and copying
      data there.  They have zero ->offset, and their ->ops points to
      default_pipe_page_ops.
      
      2) zero-copy ones - those come from copy_page_to_iter(), and page
      comes from caller.  ->offset is also caller-supplied - it might be
      non-zero.  ->ops points to page_cache_pipe_buf_ops.
      
      Move creation and insertion of those into helpers - push_anon(pipe, size)
      and push_page(pipe, page, offset, size) resp., separating them from
      the "could we avoid creating a new buffer by merging with the current
      head?" logics.

      ITER_PIPE: helper for getting pipe buffer by index · 2dcedb2a
      Al Viro authored
      pipe_buffer instances of a pipe are organized as a ring buffer,
      with power-of-2 size.  Indices are kept *not* reduced modulo ring
      size, so the buffer refered to by index N is
      	pipe->bufs[N & (pipe->ring_size - 1)].
      
      Ring size can change over the lifetime of a pipe, but not while
      the pipe is locked.  So for any iov_iter primitives it's a constant.
      Original conversion of pipes to this layout went overboard trying
      to microoptimize that - calculating pipe->ring_size - 1, storing
      it in a local variable and using through the function.  In some
      cases it might be warranted, but most of the times it only
      obfuscates what's going on in there.
      
      Introduce a helper (pipe_buf(pipe, N)) that would encapsulate
      that and use it in the obvious cases.  More will follow...

      new iov_iter flavour - ITER_UBUF · fcb14cb1
      Al Viro authored
      Equivalent of single-segment iovec.  Initialized by iov_iter_ubuf(),
      checked for by iter_is_ubuf(), otherwise behaves like ITER_IOVEC
      ones.
      
      We are going to expose the things like ->write_iter() et.al. to those
      in subsequent commits.
      
      New predicate (user_backed_iter()) that is true for ITER_IOVEC and
      ITER_UBUF; places like direct-IO handling should use that for
      checking that pages we modify after getting them from iov_iter_get_pages()
      would need to be dirtied.
      
      DO NOT assume that replacing iter_is_iovec() with user_backed_iter()
      will solve all problems - there's code that uses iter_is_iovec() to
      decide how to poke around in iov_iter guts and for that the predicate
      replacement obviously won't suffice.

        (should only affect m68k).
      
        The only major core change is the rework of async resume; the rest are
        either completely trivial or for updating deprecated APIs"

      Pull pci updates from Bjorn Helgaas:
       "Enumeration:
      
         - Consolidate duplicated 'next function' scanning and extend to allow
           'isolated functions' on s390, similar to existing hypervisors
           (Niklas Schnelle)
      
        Resource management:
         - Implement pci_iobar_pfn() for sparc, which allows us to remove the
           sparc-specific pci_mmap_page_range() and pci_mmap_resource_range().
      
           This removes the ability to map the entire PCI I/O space using
           /proc/bus/pci, but we believe that's already been broken since
           v2.6.28 (Arnd Bergmann)
      
         - Move common PCI definitions to asm-generic/pci.h and rework others
           to be be more specific and more encapsulated in arches that need
           them (Stafford Horne)
      
        Power management:
      
         - Convert drivers to new *_PM_OPS macros to avoid need for '#ifdef
           CONFIG_PM_SLEEP' or '__maybe_unused' (Bjorn Helgaas)
      
        Virtualization:
      
         - Add ACS quirk for Broadcom BCM5750x multifunction NICs that isolate
           the functions but don't advertise an ACS capability (Pavan Chebbi)
      
        Error handling:
      
         - Clear PCI Status register during enumeration in case firmware left
           errors logged (Kai-Heng Feng)
      
         - When we have native control of AER, enable error reporting for all
           devices that support AER. Previously only a few drivers enabled
           this (Stefan Roese)
      
         - Keep AER error reporting enabled for switches. Previously we
           enabled this during enumeration but immediately disabled it (Stefan
           Roese)
      
         - Iterate over error counters instead of error strings to avoid
           printing junk in AER sysfs counters (Mohamed Khalfella)
      
        ASPM:
      
         - Remove pcie_aspm_pm_state_change() so ASPM config changes, e.g.,
           via sysfs, are not lost across power state changes (Kai-Heng Feng)
      
        Endpoint framework:

         - Simplify and clean up support for the DesignWare embedded DMA
           (eDMA) controller (Frank Li, Serge Semin)
      
        Broadcom STB PCIe controller driver:
      
         - Avoid config space accesses when link is down because we can't
           recover from the CPU aborts these cause (Jim Quinlan)
      
         - Look for power regulators described under Root Ports in DT and
           enable them before scanning the secondary bus (Jim Quinlan)
      
         - Disable/enable regulators in suspend/resume (Jim Quinlan)
      
        Freescale i.MX6 PCIe controller driver:
      
         - Simplify and clean up clock and PHY management (Richard Zhu)
      
         - Disable/enable regulators in suspend/resume (Richard Zhu)

         - Make link being down a non-fatal error so controller probe doesn't
           fail if there are no Endpoints connected (Richard Zhu)

         - Add ACPI and MCFG support for Loongson LS7A (Huacai Chen)
      
         - Avoid config reads to non-existent LS2K/LS7A devices because a
           hardware defect causes machine hangs (Huacai Chen)

           Pin values (Jianmin Lv)

           Rohár)

           we skipped it if 'num-lanes' was absent (Serge Semin)
      
         - Allocate a 32-bit DMA-able page to be MSI target instead of using a

           address (Will McVicker)

      Pull clk updates from Stephen Boyd:
       "The clk core gains a new set of APIs that allow drivers to both
        acquire clks and prepare and enable them at the same time. This also
        comes with devm support so that drivers can make a single call to get
        and prepare and enable the clk and have that all undone when their
        driver is removed.
      
        Many folks have requested this feature over the years, but we've had
        disagreements about how to implement it and if it was worthwhile to
        encourage drivers to use such an API.
      
        Now it's here, so let's see how it goes.
      
        I hope that by introducing this API we can identify drivers that would
        benefit from further consolidation of clk API usage, possibly by
        moving such logic to the bus layer and out of drivers altogether.
      
        Outside of that major API update, we have the usual collection of
        driver updates. A few new SoCs are supported, mostly Qualcomm and
        Renesas this time around. Then we have the long tail of non-critical
        fixes and minor feature additions to various clk drivers.
      
        And finally more clk provider migration to struct clk_parent_data,
        reducing boot times in the process.
      
        Summary:
      
        Core:
      
         - devm helpers for clk_get() + clk_prepare() and clk_enable()
      
        New Drivers:
      
         - Support for the camera clock controller in Qualcomm SM8450 and the
           display and gpu clock controllers in Qualcomm SM8350
      
         - Add support for the Renesas RZ/Five SoC
      
        Updates:
      
         - Various fixes, new clocks and USB GDSCs are introduced for Qualcomm
           IPQ8074
      
         - Fixes to Qualcomm MSM8939 for issues introduced by inheriting the
           MSM8916 GCC driver
      
         - Support for a new type of voteable GDSCs used by Qualcomm SC8280XP
           PCIe GDSCs
      
         - Qualcomm SC8280XP pipe clocks transitioned to the new phy-mux
           implementation
      
         - Qualcomm MSM8996 GCC, RPM clock driver and some clocks in MSM8994
           GCC are migrated to use clk_parent_data
      
         - Corrected the topology for Titan (camera) GDSCs on Qualcomm SDM845
           and SM8250
      
         - Qualcomm MSM8916 gains more possible frequencies for its GP clocks.
      
         - The GCC and tsens handling on Qualcomm MSM8960 is reworked to mimic
           the design in IPQ8074 to allow the GCC driver to probe earlier.
      
         - The regulator based mmcx supply for Qualcomm dispcc and videocc is
           dropped, as the only upstream target that adapted this interface
           was transitioned several kernel versions ago
      
         - Qualcomm GDSCs found to be enabled at boot will now reflect in the
           enable count of the supply, as was done with the regulator supplies
           previously
      
         - Correct adc1, nic_media and edma1's parents for NXP i.MX93
      
         - rdiv, mfd values, the return rate in recalc_rate and add more
           frequencies in the table for fracn-gppll on i.MX
      
         - Remove Allwinner workaround logic/compatible in fixed factor code
      
         - MediaTek clk driver cleanups
      
         - Add reset support to more MediaTek clk drivers
      
         - deduplicate Allwinner ccu_clks arrays
      
         - Allwinner H6 GPU DFS support
      
         - Adjust Allwinner Kconfig to limit choice

      Linus Torvalds authored
      Pull gpio updates from Bartosz Golaszewski:
       "Here are the updates for this merge window from the GPIO subsystem.
      
        We have more lines removed than added thanks to dropping of a driver
        for a platform that's no longer supported. Otherwise the changes are
        pretty straightforward: support for some new models, various
        improvements to existing drivers, some tweaks to the core library code
        and DT bindings updates.
      
        Summary:
      
         - remove gpio-vr41xx driver as the only platform using it got dropped
           too
      
         - add support for suspend/resume to gpio-davinci
      
         - improvements to the GPIO character device code
      
         - add support for disabling bias for in-kernel users (up until now
           only user-space could set it)
      
         - drop unused devm_gpio_free()
      
         - fix a refcount issue in gpiolib OF
      
         - use device match helpers where applicable
      
         - add support for a new model to gpio-rockchip
      
         - non-functional improvements in gpio-adp5588
      
         - improve and simplify teardown in gpio-twl4030 and gpio-ucb1400
      
         - modernize the gpio-74xx-mmio and gpio-adnp drivers
      
         - coding style improvements in gpio-xilinx, gpio-104-idi-48
      
         - support new model (pca9571) in gpio-pca9570
      
         - convert the DT bindings to YAML for gpio-mvebu and update the
           document
      
         - don't return error codes from remove() in gpio-brcmstb
      
         - add a library for the intel 8255 PPI interface and use it in
           drivers
      
         - reduce using magic numbers and improve code readability in several
           drivers
      
         - convert DT bindings to YAML for gpio-tpic2810
      
         - add new models to DT bindings for gpio-frl-imx
      
         - Kconfig improvements
      
         - other minor tweaks and improvements"

      s390/dasd: Establish DMA alignment · bc792884
      Eric Farman authored
      linux-next commit bf8d0853 ("iomap: add support for dma aligned
      direct-io") changes the alignment requirement to come from the block
      device rather than the block size, and the default alignment
      requirement is 512-byte boundaries. Since DASD I/O has page
      alignments for IDAW/TIDAW requests, let's override this value to
      restore the expected behavior.
      
      Make this change for both ECKD and DIAG disciplines, as they both
      would fall into this category. Leave FBA alone, since it is always
      comprised of 512-byte blocks.

      Pull kvm updates from Paolo Bonzini:
       "Quite a large pull request due to a selftest API overhaul and some
        patches that had come in too late for 5.19.
      
        ARM:
      
         - Unwinder implementations for both nVHE modes (classic and
           protected), complete with an overflow stack
      
         - Rework of the sysreg access from userspace, with a complete rewrite
           of the vgic-v3 view to allign with the rest of the infrastructure
      
         - Disagregation of the vcpu flags in separate sets to better track
           their use model.
      
         - A fix for the GICv2-on-v3 selftest
      
         - A small set of cosmetic fixes
      
        RISC-V:
      
         - Track ISA extensions used by Guest using bitmap
      
         - Added system instruction emulation framework
      
         - Added CSR emulation framework
      
         - Added gfp_custom flag in struct kvm_mmu_memory_cache
      
         - Added G-stage ioremap() and iounmap() functions
      
         - Added support for Svpbmt inside Guest
      
        s390:
      
         - add an interface to provide a hypervisor dump for secure guests
      
         - improve selftests to use TAP interface
      
         - enable interpretive execution of zPCI instructions (for PCI
           passthrough)
      
         - First part of deferred teardown
      
         - CPU Topology
      
         - PV attestation
      
         - Minor fixes
      
        x86:
      
         - Permit guests to ignore single-bit ECC errors
      
         - Intel IPI virtualization
      
         - Allow getting/setting pending triple fault with
           KVM_GET/SET_VCPU_EVENTS
      
         - PEBS virtualization
      
         - Simplify PMU emulation by just using PERF_TYPE_RAW events
      
         - More accurate event reinjection on SVM (avoid retrying
           instructions)
      
         - Allow getting/setting the state of the speaker port data bit
      
         - Refuse starting the kvm-intel module if VM-Entry/VM-Exit controls
           are inconsistent
      
         - "Notify" VM exit (detect microarchitectural hangs) for Intel
      
         - Use try_cmpxchg64 instead of cmpxchg64
      
         - Ignore benign host accesses to PMU MSRs when PMU is disabled
      
         - Allow disabling KVM's "MONITOR/MWAIT are NOPs!" behavior
      
         - Allow NX huge page mitigation to be disabled on a per-vm basis
      
         - Port eager page splitting to shadow MMU as well
      
         - Enable CMCI capability by default and handle injected UCNA errors
      
         - Expose pid of vcpu threads in debugfs
      
         - x2AVIC support for AMD
      
         - cleanup PIO emulation
      
         - Fixes for LLDT/LTR emulation
      
         - Don't require refcounted "struct page" to create huge SPTEs
      
         - Miscellaneous cleanups:
            - MCE MSR emulation
            - Use separate namespaces for guest PTEs and shadow PTEs bitmasks
            - PIO emulation
            - Reorganize rmap API, mostly around rmap destruction
            - Do not workaround very old KVM bugs for L0 that runs with nesting enabled
            - new selftests API for CPUID
      
        Generic:
      
         - Fix races in gfn->pfn cache refresh; do not pin pages tracked by
           the cache
      
         - new selftests API using struct kvm_vcpu instead of a (vm, id)
           tuple"
