The `vcsr` only exists in the old hardware design, it isn't used in any
shipped hardware from Loongson-3A5000 on. Both scalar FP and LSX/LASX
instructions use the `fcsr` as their control and status registers now.
For example, the RM control bit in fcsr0 is shared by FP, LSX and LASX
instructions.

Particularly, fcsr16 to fcsr31 are reserved for LSX/LASX now, access to
these registers has no visible effect if LSX/LASX is enabled, and will
cause SXD/ASXD exceptions if LSX/LASX is not enabled.

So, mentions of vcsr are obsolete in the first place (it was just used
for debugging), let's remove them.

Commit fa96b57c ("LoongArch: Add build infrastructure") adds the new
file arch/loongarch/Kconfig.

As the work on LoongArch was probably quite some time under development,
various config symbols have changed and disappeared from the time of
initial writing of the Kconfig file and its inclusion in the repository.

The following four commits:

  commit c126a53c ("arch: remove GENERIC_FIND_FIRST_BIT entirely")
  commit 140c8180 ("arch: remove HAVE_COPY_THREAD_TLS")
  commit aca52c39 ("mm: remove CONFIG_HAVE_MEMBLOCK")
  commit 3f08a302 ("mm: remove CONFIG_HAVE_MEMBLOCK_NODE_MAP option")

remove the mentioned config symbol, and enable the intended setup by
default without configuration.

The decompressed kernel initially relies on the identity map set up by
the boot/compressed kernel for accessing things like boot_params. With
the recent introduction of SEV-SNP support, the decompressed kernel
also needs to access the setup_data entries pointed to by
boot_params->hdr.setup_data.

This can lead to a crash in the kexec kernel during early boot due to
these entries not currently being included in the initial identity map,
see thread at Link below.

Include mappings for the setup_data entries in the initial identity map.

This unfortunately caused a regression on a vartiety of AMD
platforms in the field because a number of AMD platforms don't set
the `_OSC` bit 5 or 6 to indicate CPPC or CPPC v2 support.

As these AMD platforms already claim CPPC support via a dedicated
MSR from `X86_FEATURE_CPPC`, use this enable this feature rather
than requiring the `_OSC` on platforms with a dedicated MSR.

If there is additional breakage on the shared memory designs also
missing this _OSC, additional follow up changes may be needed.

The USBH composed of EHCI and OHCI controllers needs the PHY clock to be
initialized first, before enabling (gating) them. The reverse is also
required when going to suspend.
So, add USBPHY clock as 1st entry in both controllers, so the USBPHY PLL
gets enabled 1st upon controller init. Upon suspend/resume, this also makes
the clock to be disabled/re-enabled in the correct order.
This fixes some IRQ storm conditions seen when going to low-power, due to
PHY PLL being disabled before all clocks are cleanly gated.

Addition of vDSO support for parisc in kernel v5.18 suddenly broke glibc
signal testcases on a 32-bit kernel.

The trampoline code (sigtramp.S) which is mapped into userspace includes
an offset to the context data on the stack, which is used by gdb and
glibc to get access to registers.

In a 32-bit kernel we used by mistake the offset into the compat context
(which is valid on a 64-bit kernel only) instead of the offset into the
"native" 32-bit context.

Commit fb396bb4 ("arm64/hugetlb: Drop TLB flush from get_clear_flush()")
removed TLB invalidation from get_clear_flush() [now get_clear_contig()]
on the basis that the core TLB invalidation code is aware of hugetlb
mappings backed by contiguous page-table entries and will cover the
correct virtual address range.

However, this change also resulted in the TLB invalidation being removed
from the "break" step in the break-before-make (BBM) sequence used
internally by huge_ptep_set_{access_flags,wrprotect}(), therefore
making the BBM sequence unsafe irrespective of later invalidation.

Although the architecture is desperately unclear about how exactly
contiguous ptes should be updated in a live page-table, restore TLB
invalidation to our BBM sequence under the assumption that BBM is the
right thing to be doing in the first place.

Commit in Fixes added the "NOLOAD" attribute to the .brk section as a
"failsafe" measure.

Unfortunately, this leads to the linker no longer covering the .brk
section in a program header, resulting in the kernel loader not knowing
that the memory for the .brk section must be reserved.

This has led to crashes when loading the kernel as PV dom0 under Xen,
but other scenarios could be hit by the same problem (e.g. in case an
uncompressed kernel is used and the initrd is placed directly behind
it).

So drop the "NOLOAD" attribute. This has been verified to correctly
cover the .brk section by a program header of the resulting ELF file.

The .brk section has the same properties as .bss: it is an alloc-only
section and should be cleared before being used.

Not doing so is especially a problem for Xen PV guests, as the
hypervisor will validate page tables (check for writable page tables
and hypervisor private bits) before accepting them to be used.

Make sure .brk is initially zero by letting clear_bss() clear the brk
area, too.

During the PV driver life cycle the mappings are added to
the RB-tree by set_foreign_p2m_mapping(), which is called from
gnttab_map_refs() and are removed by clear_foreign_p2m_mapping()
which is called from gnttab_unmap_refs(). As both functions end
up calling __set_phys_to_machine_multi() which updates the RB-tree,
this function can be called concurrently.

There is already a "p2m_lock" to protect against concurrent accesses,
but the problem is that the first read of "phys_to_mach.rb_node"
in __set_phys_to_machine_multi() is not covered by it, so this might
lead to the incorrect mappings update (removing in our case) in RB-tree.

In my environment the related issue happens rarely and only when
PV net backend is running, the xen_add_phys_to_mach_entry() claims
that it cannot add new pfn <-> mfn mapping to the tree since it is
already exists which results in a failure when mapping foreign pages.

But there might be other bad consequences related to the non-protected
root reads such use-after-free, etc.

While at it, also fix the similar usage in __pfn_to_mfn(), so
initialize "struct rb_node *n" with the "p2m_lock" held in both
functions to avoid possible bad consequences.

s390x appears to present two RNG interfaces:
- a "TRNG" that gathers entropy using some hardware function; and
- a "DRBG" that takes in a seed and expands it.

Previously, the TRNG was wired up to arch_get_random_{long,int}(), but
it was observed that this was being called really frequently, resulting
in high overhead. So it was changed to be wired up to arch_get_random_
seed_{long,int}(), which was a reasonable decision. Later on, the DRBG
was then wired up to arch_get_random_{long,int}(), with a complicated
buffer filling thread, to control overhead and rate.

Fortunately, none of the performance issues matter much now. The RNG
always attempts to use arch_get_random_seed_{long,int}() first, which
means a complicated implementation of arch_get_random_{long,int}() isn't
really valuable or useful to have around. And it's only used when
reseeding, which means it won't hit the high throughput complications
that were faced before.

So this commit returns to an earlier design of just calling the TRNG in
arch_get_random_seed_{long,int}(), and returning false in arch_get_
random_{long,int}().

Part of what makes the simplification possible is that the RNG now seeds
itself using the TRNG at bootup. But this only works if the TRNG is
detected early in boot, before random_init() is called. So this commit
also causes that check to happen in setup_arch().

The eeprom memories on the board are microchip 24aa025e48, which are 2 Kbits
and are compatible with at24c02 not at24c32.

The board has a microchip 24aa025e48 eeprom, which is a 2 Kbits memory,
so it's compatible with at24c02 not at24c32.
Also the size property is wrong, it's not 128 bytes, but 256 bytes.
Thus removing and leaving it to the default (256).

"make dtbs_check" complains about the missing "-supply" suffix for
vdd_lvs1_2 which is clearly a typo, originally introduced in the
msm8994-smd-rpm.dtsi file and apparently later copied to
msm8992-xiaomi-libra.dts:

The commit e8aa7b17 broke the 32-bit load-word unalignment exception
handler because it calculated the wrong amount of bits by which the value
