A number of arches (EXYNOS/IMX/TEGRA) are separated out into finer grained
definitions whether it be sub ARCH or SOC definitions. The device tree blobs
should only be built if the specific option is enabled that supports that
device or it might be that there's an expectation that the device is supported
when in actual fact it's not. This ensures only the relevant bits are built.
Also standardised the line break between the arch/soc definitions and the
dtbs to be on separate lines for better consistency as per feedback.

There was another report of a boot failure with a #GP fault in the
uncore SBOX initialization. The earlier work around was not enough
for this system.
The boot was failing while trying to initialize the third SBOX.
This patch detects parts with only two SBOXes and limits the number
of SBOX units to two there.
Stable material, as it affects boot problems on 3.18.

Perf reports user regs for kernel-mode samples so that samples can
be backtraced through user code. The old code was very broken in
syscall context, resulting in useless backtraces.
The new code, in contrast, is still dangerously racy, but it should
at least work most of the time.

On x86_64, at least, task_pt_regs may be only partially initialized
in many contexts, so x86_64 should not use it without extra care
from interrupt context, let alone NMI context.
This will allow x86_64 to override the logic and will supply some
scratch space to use to make a cleaner copy of user regs.

- Fix ACPI power management intialization for device objects
corresponding to devices that are not present at the init time
(the _STA control method returns 0 for them) and therefore should
not be regarded as power manageable (Rafael J Wysocki).
- Rename a structure field and two functions used by the ACPI
processor driver to make them less tied to architectures that
use APICs (both x86 and ia64) and more suitable for ARM64
processors (Hanjun Guo).
- Add a disable_native_backlight quirk for Dell XPS15 L521X
designed in an unusual way preventing native backlight from
working on that machine (Hans de Goede).

"These are an ACPI device power management initialization fix (-stable
material), two commits renaming stuff in the ACPI processor driver to
make it more suitable for ARM64 processors and a new ACPI backlight
blacklist entry.
Specifics:
- Fix ACPI power management intialization for device objects
corresponding to devices that are not present at the init time (the
_STA control method returns 0 for them) and therefore should not be
regarded as power manageable (Rafael J Wysocki).
- Rename a structure field and two functions used by the ACPI
processor driver to make them less tied to architectures that use
APICs (both x86 and ia64) and more suitable for ARM64 processors
(Hanjun Guo).
- Add a disable_native_backlight quirk for Dell XPS15 L521X designed
in an unusual way preventing native backlight from working on that
machine (Hans de Goede)"

The early ioremap support introduced by patch bf4b558eba
("arm64: add early_ioremap support") failed to add a call to
early_ioremap_reset() at an appropriate time. Without this call,
invocations of early_ioremap etc. that are done too late will go
unnoticed and may cause corruption.
This is exactly what happened when the first user of this feature
was added in patch f84d02755f ("arm64: add EFI runtime services").
The early mapping of the EFI memory map is unmapped during an early
initcall, at which time the early ioremap support is long gone.
Fix by adding the missing call to early_ioremap_reset() to
setup_arch(), and move the offending early_memunmap() to right after
the point where the early mapping of the EFI memory map is last used.

Now local variables kernel_x_start and kernel_x_end defined using
'unsigned long' type which is wrong because they represent physical
memory range and will be calculated wrongly if LPAE is enabled.
As result, all following code in map_lowmem() will not work correctly.
For example, Keystone 2 boot is broken because
kernel_x_start == 0x0000 0000
kernel_x_end == 0x0080 0000
instead of
kernel_x_start == 0x0000 0008 0000 0000
kernel_x_end == 0x0000 0008 0080 0000
and as result whole low memory will be mapped with MT_MEMORY_RW
permissions by code (start > kernel_x_end):
} else if (start >= kernel_x_end) {
map.pfn = __phys_to_pfn(start);
map.virtual = __phys_to_virt(start);
map.length = end - start;
map.type = MT_MEMORY_RW;
create_mapping(&map);
}
Hence, fix it by using phys_addr_t type for variables kernel_x_start
and kernel_x_end.

Currently the arm page table dumping code starts dumping page tables
from USER_PGTABLES_CEILING. This is unnecessary for skipping any entries
related to userspace as the swapper_pg_dir does not contain such
entries, and results in a couple of unfortuante side effects.
Firstly, any kernel mappings which might exist below
USER_PGTABLES_CEILING will not be accounted in the dump output. This
masks any entries erroneously created below this address.
Secondly, if the final page table entry walked is part of a valid
mapping the page table dumping code will not log the region this entry
is part of, as the final note_page call in walk_pgd will trigger an
early return when 0 < USER_PGTABLES_CEILING. Luckily this isn't seen on
contemporary systems as they typically don't have enough RAM to extend
the linear mapping right to the end of the address space.
Due to the way addr is constructed in the walk_* functions, it can never
be less than USER_PGTABLES_CEILING when walking the page tables, so it
is not necessary to avoid dereferencing invalid table addresses. The
existing checks for st->current_prot and st->marker[1].start_address are
sufficient to ensure we will not print and/or dereference garbage when
trying to log information.
This patch removes both problematic uses of USER_PGTABLES_CEILING from
the arm page table dumping code, preventing both of these issues. We
will now report any low mappings, and the final note_page call will not
return early, ensuring all regions are logged.

Commit 97b56be103 (arm64: compat: Enable bpf syscall) made the
usual mistake of forgetting to update __NR_compat_syscalls. Due to this,
when el0_sync_compat calls el0_svc_naked, the test against sc_nr
(__NR_compat_syscalls) will fail, and we'll call ni_sys, returning
-ENOSYS to userspace.
This patch bumps __NR_compat_syscalls appropriately, enabling the use of
the bpf syscall from compat tasks.
Due to the reorganisation of unistd{,32}.h as part of commit
f3e5c847ec (arm64: Add __NR_* definitions for compat syscalls) it
is not currently possible to include both headers and sanity-check the
value of __NR_compat_syscalls at build-time to prevent this from
happening again. Additional rework is required to make such niceties a
possibility.

The "by8" counter mode optimization is broken for 128 bit keys with
input data longer than 128 bytes. It uses the wrong key material for
en- and decryption.
The key registers xkey0, xkey4, xkey8 and xkey12 need to be preserved
in case we're handling more than 128 bytes of input data -- they won't
get reloaded after the initial load. They must therefore be (a) loaded
on the first iteration and (b) be preserved for the latter ones. The
implementation for 128 bit keys does not comply with (a) nor (b).
Fix this by bringing the implementation back to its original source
and correctly load the key registers and preserve their values by
*not* re-using the registers for other purposes.
Kudos to James for reporting the issue and providing a test case
showing the discrepancies.

but it doesn't have the desired effect as it's nevertheless being placed
