The include/linux/reset directory currently contains one header with helper functions for Broadcom BCM63xx PMB, which can control reset lines to on-chip peripherals. Even though that driver doesn't use the reset controller framework, the the directory can be shared with other reset controller drivers that do.

UNAME26 is a mechanism to report Linux's version as 2.6.x, for compatibility with old/broken software. Due to the way it is implemented, it would have to be updated after 5.0, to keep the resulting versions unique. Linus Torvalds argued: "Do we actually need this? I'd rather let it bitrot, and just let it return random versions. It will just start again at 2.4.60, won't it? Anybody who uses UNAME26 for a 5.x kernel might as well think it's still 4.x. The user space is so old that it can't possibly care about differences between 4.x and 5.x, can it? The only thing that matters is that it shows "2.4.<largeenough>", which it will do regardless" Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Pull ARM SoC fixes from Olof Johansson: "A bigger batch than I anticipated this week, for two reasons: - Some fallout on Davinci from board file -> DTB conversion, that also includes a few longer-standing fixes (i.e. not recent regressions). - drivers/reset material that has been in linux-next for a while, but didn't get sent to us until now for a variety of reasons (maintainer out sick, holidays, etc). There's a functional dependency in there such that one platform (Altera's SoCFPGA) won't boot without one of the patches; instead of reverting the patch that got merged, I looked at this set and decided it was small enough that I'll pick it up anyway. If you disagree I can revisit with a smaller set. That being said, there's also a handful of the usual stuff: - Fix for a crash on Armada 7K/8K when the kernel touches PSCI-reserved memory - Fix for PCIe reset on Macchiatobin (Armada 8K development board, what this email is sent from in fact :) - Enable a few new-merged modules for Amlogic in arm64 defconfig - Error path fixes on Integrator - Build fix for Renesas and Qualcomm - Initialization fix for Renesas RZ/G2E .. plus a few more fixlets" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (28 commits) ARM: integrator: impd1: use struct_size() in devm_kzalloc() qcom-scm: Include <linux/err.h> header gpio: pl061: handle failed allocations ARM: dts: kirkwood: Fix polarity of GPIO fan lines arm64: dts: marvell: mcbin: fix PCIe reset signal arm64: dts: marvell: armada-ap806: reserve PSCI area ARM: dts: da850-lcdk: Correct the sound card name ARM: dts: da850-lcdk: Correct the audio codec regulators ARM: dts: da850-evm: Correct the sound card name ARM: dts: da850-evm: Correct the audio codec regulators ARM: davinci: omapl138-hawk: fix label names in GPIO lookup entries ARM: davinci: dm644x-evm: fix label names in GPIO lookup entries ARM: davinci: dm355-evm: fix label names in GPIO lookup entries ARM: davinci: da850-evm: fix label names in GPIO lookup entries ARM: davinci: da830-evm: fix label names in GPIO lookup entries arm64: defconfig: enable modules for amlogic s400 sound card reset: uniphier-glue: Add AHCI reset control support in glue layer dt-bindings: reset: uniphier: Add AHCI core reset description reset: uniphier-usb3: Rename to reset-uniphier-glue dt-bindings: reset: uniphier: Replace the expression of USB3 with generic peripherals ...

Commit 49e54187 ("ata: libahci_platform: comply to PHY framework") uses the PHY_MODE_SATA, but that enum had not yet been added. This caused a build failure for me, with today's linux.git. Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding in the Marvell Berlin SATA PHY driver. Fix the build by: 1) Renaming Marvell's defined value to a more scoped name, in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA. 2) Adding the missing enum, which was going to be added anyway as part of [1].

Pull dma_zalloc_coherent() removal from Christoph Hellwig: "We've always had a weird situation around dma_zalloc_coherent. To safely support mapping the allocations to userspace major architectures like x86 and arm have always zeroed allocations from dma_alloc_coherent, but a couple other architectures were missing that zeroing either always or in corner cases. Then later we grew anothe dma_zalloc_coherent interface to explicitly request zeroing, but that just added __GFP_ZERO to the allocation flags, which for some allocators that didn't end up using the page allocator ended up being a no-op and still not zeroing the allocations. So for this merge window I fixed up all remaining architectures to zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a no-op wrapper around dma_alloc_coherent, which fixes all of the above issues. dma_zalloc_coherent is now pointless and can go away, and Luis helped me writing a cocchinelle script and patch series to kill it, which I think we should apply now just after -rc1 to finally settle these issue" * tag 'remove-dma_zalloc_coherent-5.0' of git://git.infradead.org/users/hch/dma-mapping: dma-mapping: remove dma_zalloc_coherent() cross-tree: phase out dma_zalloc_coherent() on headers cross-tree: phase out dma_zalloc_coherent()

A feature has been added in the libahci driver: the possibility to set a new flag in hpriv->flags to let the core handle PHY suspend/resume automatically.

Miquel Raynal authored
A3700 comphy initialization is done in the firmware (TF-A). Looking at the SATA PHY initialization routine, there is a comment about "vendor specific" registers. Two registers are mentioned. They are not initialized there in the firmware because they are AHCI related, while the firmware at this location does only PHY configuration. The solution to avoid doing such initialization is relying on U-Boot. While this work at boot time, U-Boot is definitely not going to run during a resume after suspending to RAM. Two possible solutions were considered: * Fixing the firmware. * Fixing the kernel driver. The first solution would take ages to propagate, while the second solution is easy to implement as the driver as been a little bit reworked to prepare for such platform configuration. Hence, this patch adds an Armada 3700 configuration function to set these two registers both at boot time (in the probe) and after a suspend (in the resume path).

At the beginning, only Armada 38x SoCs where supported by the ahci_mvebu.c driver. Commit 15d3ce7b ("ata: ahci_mvebu: add support for Armada 3700 variant") introduced Armada 3700 support. As opposed to Armada 38x SoCs, the 3700 variants do not have to configure mbus and the regret option. This patch took care of avoiding such configuration when not needed in the probe function, but failed to do the same in the resume path. While doing so looks harmless by experience, let's clean the driver logic and avoid doing this useless configuration with Armada 3700 SoCs. Because the logic is very similar between these two places, it has been decided to factorize this code and put it in a "Armada 38x configuration function". This function is part of a new (per-compatible) platform data structure, so that the addition of such configuration function for Armada 3700 will be eased.

There are even suspend/resume hooks in this driver since: commit d6ecf158 ("ata: ahci_mvebu: add suspend/resume support") Remove the stale comment at the end of this driver stating that all the above does not exist yet.

Current implementation of the libahci does not take into account the new PHY framework. Correct the situation by adding a call to phy_set_mode() before phy_power_on(). PHYs should also be handled at suspend/resume time. For this, call ahci_platform_enable/disable_phys() at suspend/resume_host() time. These calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of the libahci driver must set manually in hpriv->flags at probe time. This is to avoid breaking users that have not been tested with this change.

Most of the diffstat is dominated by a PowerPC related fix of system call trace output beautification that allows us to (again) use the UAPI header version and sync up with the kernel's version of PowerPC system call names in the arch/powerpc/kernel/syscalls/syscall.tbl header" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits) tools headers powerpc: Remove unistd.h perf powerpc: Rework syscall table generation perf symbols: Add 'arch_cpu_idle' to the list of kernel idle symbols tools include uapi: Sync linux/if_link.h copy with the kernel sources tools include uapi: Sync linux/vhost.h with the kernel sources tools include uapi: Sync linux/fs.h copy with the kernel sources perf beauty: Switch from using uapi/linux/fs.h to uapi/linux/mount.h tools include uapi: Grab a copy of linux/mount.h perf top: Lift restriction on using callchains without "sym" in --sort tools lib traceevent: Remove tep_data_event_from_type() API tools lib traceevent: Rename tep_is_file_bigendian() to tep_file_bigendian() tools lib traceevent: Changed return logic of tep_register_event_handler() API tools lib traceevent: Changed return logic of trace_seq_printf() and trace_seq_vprintf() APIs tools lib traceevent: Rename struct cmdline to struct tep_cmdline tools lib traceevent: Initialize host_bigendian at tep_handle allocation tools lib traceevent: Introduce new libtracevent API: tep_override_comm() perf tests: Add a test for the ARM 32-bit [vectors] page perf tools: Make find_vdso_map() more modular perf trace: Fix alignment for [continued] lines perf trace: Fix ')' placement in "interrupted" syscall lines ...

Since commit 09abb5e3 ("KVM: nVMX: call kvm_skip_emulated_instruction in nested_vmx_{fail,succeed}") nested_vmx_failValid() results in kvm_skip_emulated_instruction() so doing it again in handle_vmptrld() when vmptr address is not backed is wrong, we end up advancing RIP twice.

The "ret" is initialized to be ENOTSUPP. The return value of __hv_remote_flush_tlb_with_range() will be Or with "ret" when ept table potiners are mismatched. This will cause return ENOTSUPP even if flush tlb successfully. This patch is to fix the issue and set "ret" to 0. Fixes: a5c214da ("KVM/VMX: Change hv flush logic when ept tables are mismatched.")

By code inspection, it was found that multiple calls to KVM_SEV_INIT could deplete asid bits and overwrite kvm_sev_info's regions_list. Multiple calls to KVM_SVM_INIT is not likely to occur with QEMU, but this should likely be fixed anyway. This code is serialized by kvm->lock.

The function at issue does not fully validate the content of the structure pointed by the log parameter, though its content has just been copied from userspace and lacks validation. Fix that. Moreover, change the type of n to unsigned long as that is the type returned by kvm_dirty_bitmap_bytes().
