Instead of using GUP, make fault_in_safe_writeable() actually force a
'handle_mm_fault()' using the same fixup_user_fault() machinery that
futexes already use.

Using the GUP machinery meant that fault_in_safe_writeable() did not do
everything that a real fault would do, ranging from not auto-expanding
the stack segment, to not updating accessed or dirty flags in the page
tables (GUP sets those flags on the pages themselves).

The latter causes problems on architectures (like s390) that do accessed
bit handling in software, which meant that fault_in_safe_writeable()
didn't actually do all the fault handling it needed to, and trying to
access the user address afterwards would still cause faults.

Legacy and old PCI I/O based cards do not support 32-bit I/O addressing.

Since commit 64f160e1 ("PCI: aardvark: Configure PCIe resources from
'ranges' DT property") kernel can set different PCIe address on CPU and
different on the bus for the one A37xx address mapping without any firmware
support in case the bus address does not conflict with other A37xx mapping.

So remap I/O space to the bus address 0x0 to enable support for old legacy
I/O port based cards which have hardcoded I/O ports in low address space.

Note that DDR on A37xx is mapped to bus address 0x0. And mapping of I/O
space can be set to address 0x0 too because MEM space and I/O space are
separate and so do not conflict.

Remapping IO space on Turris Mox to different address is not possible to
due bootloader bug.

This works around an issue with the hardware where both OE and
DAT are exposed in the same register. If both are updated
simultaneously, the harware makes no guarantees that OE or DAT
will actually change in any given order and may result in a
glitch of a few ns on a GPIO pin when changing direction and value
in a single write.

Setting direction to input now only affects OE bit. Setting
direction to output updates DAT first, then OE.

 "Several Linux PV device frontends are using the grant table interfaces
  for removing access rights of the backends in ways being subject to
  race conditions, resulting in potential data leaks, data corruption by
  malicious backends, and denial of service triggered by malicious
  backends:

   - blkfront, netfront, scsifront and the gntalloc driver are testing
     whether a grant reference is still in use. If this is not the case,
     they assume that a following removal of the granted access will
     always succeed, which is not true in case the backend has mapped
     the granted page between those two operations.

     As a result the backend can keep access to the memory page of the
     guest no matter how the page will be used after the frontend I/O
     has finished. The xenbus driver has a similar problem, as it
     doesn't check the success of removing the granted access of a
     shared ring buffer.

   - blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p,
     kbdfront, and pvcalls are using a functionality to delay freeing a
     grant reference until it is no longer in use, but the freeing of
     the related data page is not synchronized with dropping the granted
     access.

     As a result the backend can keep access to the memory page even
     after it has been freed and then re-used for a different purpose.

   - netfront will fail a BUG_ON() assertion if it fails to revoke
     access in the rx path.

     This will result in a Denial of Service (DoS) situation of the
     guest which can be triggered by the backend"

When building arm64 defconfig + CONFIG_LTO_CLANG_{FULL,THIN}=y after
commit 558c303c ("arm64: Mitigate spectre style branch history side
channels"), the following error occurs:

  <instantiation>:4:2: error: invalid fixup for movz/movk instruction
   mov w0, #ARM_SMCCC_ARCH_WORKAROUND_3
   ^

Marc figured out that moving "#include <linux/init.h>" in
include/linux/arm-smccc.h into a !__ASSEMBLY__ block resolves it. The
full include chain with CONFIG_LTO=y from include/linux/arm-smccc.h:

include/linux/init.h
include/linux/compiler.h
arch/arm64/include/asm/rwonce.h
arch/arm64/include/asm/alternative-macros.h
arch/arm64/include/asm/assembler.h

The asm/alternative-macros.h include in asm/rwonce.h only happens when
CONFIG_LTO is set, which ultimately casues asm/assembler.h to be
included before the definition of ARM_SMCCC_ARCH_WORKAROUND_3. As a
result, the preprocessor does not expand ARM_SMCCC_ARCH_WORKAROUND_3 in
__mitigate_spectre_bhb_fw, which results in the error above.

Avoid this problem by just avoiding the CONFIG_LTO=y __READ_ONCE() block
in asm/rwonce.h with assembly files, as nothing in that block is useful
to assembly files, which allows ARM_SMCCC_ARCH_WORKAROUND_3 to be
properly expanded with CONFIG_LTO=y builds.

DPI support relies on the bus-type enum which does not yet support
Mipi DPI, since no v4l2_fwnode_bus_type has been defined for this
bus type.

When DPI for anx7625 was initially added, it assumed that
V4L2_FWNODE_BUS_TYPE_PARALLEL was the correct bus type for
representing DPI, which it is not.

max_seg_size is unsigned int and it can have a value up to 2^32
(for eg:-RZ_DMAC driver sets dma_set_max_seg_size as U32_MAX)
When this value is used in min_t() as an integer type, it becomes
-1 and the value of sgs becomes 0.

Fix this issue by replacing the 'int' data type with 'unsigned int'
in min_t().

Commit 18107f8a ("arm64: Support execute-only permissions with
Enhanced PAN") re-introduced execute-only permissions when EPAN is
available. When EPAN is not available, arch_filter_pgprot() is supposed
to change a PAGE_EXECONLY permission into PAGE_READONLY_EXEC. However,
if BTI or MTE are present, such check does not detect the execute-only
pgprot in the presence of PTE_GP (BTI) or MT_NORMAL_TAGGED (MTE),
allowing the user to request PROT_EXEC with PROT_BTI or PROT_MTE.

Remove the arch_filter_pgprot() function, change the default VM_EXEC
permissions to PAGE_READONLY_EXEC and update the protection_map[] array
at core_initcall() if EPAN is detected.

Pull x86 spectre fixes from Borislav Petkov:

 - Mitigate Spectre v2-type Branch History Buffer attacks on machines
   which support eIBRS, i.e., the hardware-assisted speculation
   restriction after it has been shown that such machines are vulnerable
   even with the hardware mitigation.

 - Do not use the default LFENCE-based Spectre v2 mitigation on AMD as
   it is insufficient to mitigate such attacks. Instead, switch to
   retpolines on all AMD by default.

 - Update the docs and add some warnings for the obviously vulnerable
   cmdline configurations.

Pull MTD fix from Miquel Raynal:
 "As part of a previous changeset introducing support for the K3
  architecture, the OMAP_GPMC (a non visible symbol) got selected by the
  selection of MTD_NAND_OMAP2 instead of doing so from the architecture
  directly (like for the other users of these two drivers). Indeed, from
  a hardware perspective, the OMAP NAND controller needs the GPMC to
  work.

  This led to a robot error which got addressed in fix merge into -rc4.
  Unfortunately, the approach at this time still used "select" and lead
  to further build error reports (sparc64:allmodconfig).

  This time we switch to 'depends on' in order to prevent random
  misconfigurations. The different dependencies will however need a
  future cleanup"
