7b0eb6b41a arm64: fix vmemmap BUILD_BUG_ON() triggering on !vmemmap setups
Arnd reports the following arm64 randconfig build error with the PSI
patches that add another page flag:

  /git/arm-soc/arch/arm64/mm/init.c: In function 'mem_init':
  /git/arm-soc/include/linux/compiler.h:357:38: error: call to
  '__compiletime_assert_618' declared with attribute error: BUILD_BUG_ON
  failed: sizeof(struct page) > (1 << STRUCT_PAGE_MAX_SHIFT)

The additional page flag causes other information stored in
page->flags to get bumped into their own struct page member:

  #if SECTIONS_WIDTH+ZONES_WIDTH+NODES_SHIFT+LAST_CPUPID_SHIFT <=
  BITS_PER_LONG - NR_PAGEFLAGS
  #define LAST_CPUPID_WIDTH LAST_CPUPID_SHIFT
  #else
  #define LAST_CPUPID_WIDTH 0
  #endif

  #if defined(CONFIG_NUMA_BALANCING) && LAST_CPUPID_WIDTH == 0
  #define LAST_CPUPID_NOT_IN_PAGE_FLAGS
  #endif

which in turn causes the struct page size to exceed the size set in
STRUCT_PAGE_MAX_SHIFT. This value is an an estimate used to size the
VMEMMAP page array according to address space and struct page size.

However, the check is performed - and triggers here - on a !VMEMMAP
config, which consumes an additional 22 page bits for the sparse
section id. When VMEMMAP is enabled, those bits are returned, cpupid
doesn't need its own member, and the page passes the VMEMMAP check.

Restrict that check to the situation it was meant to check: that we
are sizing the VMEMMAP page array correctly.

Says Arnd:

    Further experiments show that the build error already existed before,
    but was only triggered with larger values of CONFIG_NR_CPU and/or
    CONFIG_NODES_SHIFT that might be used in actual configurations but
    not in randconfig builds.

    With longer CPU and node masks, I could recreate the problem with
    kernels as old as linux-4.7 when arm64 NUMA support got added.

dc0e36581e arm64: Check for errata before evaluating cpu features
Since commit d3aec8a28be3b8 ("arm64: capabilities: Restrict KPTI
detection to boot-time CPUs") we rely on errata flags being already
populated during feature enumeration. The order of errata and
features was flipped as part of commit ed478b3f9e4a ("arm64:
capabilities: Group handling of features and errata workarounds").

Return to the orginal order of errata and feature evaluation to
ensure errata flags are present during feature evaluation.

2c870e6113 arm64: fix ACPI dependencies
Kconfig reports a warning on x86 builds after the ARM64 dependency
was added.

drivers/acpi/Kconfig:6:error: recursive dependency detected!
drivers/acpi/Kconfig:6:       symbol ACPI depends on EFI

This rephrases the dependency to keep the ARM64 details out of the
shared Kconfig file, so Kconfig no longer gets confused by it.

For consistency, all three architectures that support ACPI now
select ARCH_SUPPORTS_ACPI in exactly the configuration in which
they allow it. We still need the 'default x86', as each one
wants a different default: default-y on x86, default-n on arm64,
and always-y on ia64.

	Kernel panic - not syncing: Fatal exception
	Rebooting in 10 seconds..

(diagnosis)
* This fault is a data abort, alignment fault (ESR=0x96000021)
  during reading out ACPI table.
* Initial ACPI tables are normally stored in system ram and marked as
  "ACPI Reclaim memory" by the firmware.
* After the commit f56ab9a5b73c ("efi/arm: Don't mark ACPI reclaim
  memory as MEMBLOCK_NOMAP"), those regions are differently handled
  as they are "memblock-reserved", without NOMAP bit.
* So they are now excluded from device tree's "usable-memory-range"
  which kexec-tools determines based on a current view of /proc/iomem.
* When crash dump kernel boots up, it tries to accesses ACPI tables by
  mapping them with ioremap(), not ioremap_cache(), in acpi_os_ioremap()
  since they are no longer part of mapped system ram.
* Given that ACPI accessor/helper functions are compiled in without
  unaligned access support (ACPI_MISALIGNMENT_NOT_SUPPORTED),
  any unaligned access to ACPI tables can cause a fatal panic.

With this patch, acpi_os_ioremap() always honors memory attribute
information provided by the firmware (EFI) and retaining cacheability
allows the kernel safe access to ACPI tables.

50d7ba36b9 arm64: export memblock_reserve()d regions via /proc/iomem
There has been some confusion around what is necessary to prevent kexec
overwriting important memory regions. memblock: reserve, or nomap?
Only memblock nomap regions are reported via /proc/iomem, kexec's
user-space doesn't know about memblock_reserve()d regions.

Until commit f56ab9a5b73ca ("efi/arm: Don't mark ACPI reclaim memory
as MEMBLOCK_NOMAP") the ACPI tables were nomap, now they are reserved
and thus possible for kexec to overwrite with the new kernel or initrd.
But this was always broken, as the UEFI memory map is also reserved
and not marked as nomap.

Exporting both nomap and reserved memblock types is a nuisance as
they live in different memblock structures which we can't walk at
the same time.

Take a second walk over memblock.reserved and add new 'reserved'
subnodes for the memblock_reserved() regions that aren't already
described by the existing code. (e.g. Kernel Code)

We use reserve_region_with_split() to find the gaps in existing named
regions. This handles the gap between 'kernel code' and 'kernel data'
which is memblock_reserve()d, but already partially described by
request_standard_resources(). e.g.:
| 80000000-dfffffff : System RAM
|   80080000-80ffffff : Kernel code
|   81000000-8158ffff : reserved
|   81590000-8237efff : Kernel data
|   a0000000-dfffffff : Crash kernel
| e00f0000-f949ffff : System RAM

reserve_region_with_split needs kzalloc() which isn't available when
request_standard_resources() is called, use an initcall.

c4db9c1e8c efi: Deduplicate efi_open_volume()
There's one ARM, one x86_32 and one x86_64 version of efi_open_volume()
which can be folded into a single shared version by masking their
differences with the efi_call_proto() macro introduced by commit:

  3552fdf29f01 ("efi: Allow bitness-agnostic protocol calls").

To be able to dereference the device_handle attribute from the
efi_loaded_image_t table in an arch- and bitness-agnostic manner,
introduce the efi_table_attr() macro (which already exists for x86)
to arm and arm64.

No functional change intended.

currently doesn't have any peripherals under qupv3_id_0.  If any board
was currently using peripherals under qupv3_id_0 then that board would
need to add this snippet to their board dts file:

897cf34e73 arm64: dts: qcom: sdm845: Add I2C, SPI, and UART9 nodes
This adds nodes to SDM845-dtsi for all the I2C ports, all the SPI
ports, and UART9.  Note that I2C / SPI / UART are a bit strange on
sdm845 because each "serial engine" has 4 pins associated with it and
depending on which firmware has been loaded into the serial engine
(loaded by the BIOS) the serial engine can behave like an I2C port, a
SPI port, or a UART.  As per the landed bindings that means that we
need to create one node for each possible mode that the port could be
in.  With 16 serial engines that means 16 x 3 = 48 nodes.

We get away with only creating 33 nodes for now because it seems very
likely that SDM845-based boards will actually all use the same UART
(UART 9) for debug purposes.  While another UART could be used for
something like Bluetooth communication we can cross that path when we
come to it.  Some documentation that I saw implied that using a UART
for "high speed" communications actually needs yet another different
serial engine firmware anyway.

Note that quick measurements adding all these nodes adds <10k of extra
space per dtb that they're included with.  If this becomes a problem
we may need to think of a different way to structure this so that
boards only get the nodes they need (or figure out how to get dtc to
strip 'disabled' nodes).  For now it seems OK.

These nodes were programmatically generated with a fairly dumb python
script.  See http://crosreview.com/1091631 for the source.

NOTE: at the moment SPI chip select doesn't appear to work in my tests
with the latest posted SPI driver.  All testing of SPI with this patch
has been done by hacking SPI to GPIO chip select.
