Before attempting to support the pre-ratification version of vector
found on older T-Head CPUs, disallow "v" in riscv,isa on these
platforms. The deprecated property has no clear way to communicate
the specific version of vector that is supported and much of the vendor
provided software puts "v" in the isa string. riscv,isa-extensions
should be used instead. This should not be too much of a burden for
these systems, as the vendor shipped devicetrees and firmware do not
work with a mainline kernel and will require updating.

We can limit this restriction to only ignore v in riscv,isa on CPUs
that report T-Head's vendor ID and a zero marchid. Newer T-Head CPUs
that support the ratified version of vector should report non-zero
marchid, according to Guo Ren [1].

CALLER_ADDRx returns caller's address at specified level, they are used
for several tracers. These macros eventually use
__builtin_return_address(n) to get the caller's address if arch doesn't
define their own implementation.

In RISC-V, __builtin_return_address(n) only works when n == 0, we need
to walk the stack frame to get the caller's address at specified level.

data.level started from 'level + 3' due to the call flow of getting
caller's address in RISC-V implementation. If we don't have additional
three iteration, the level is corresponding to follows:

callsite -> return_address -> arch_stack_walk -> walk_stackframe
|           |                 |                  |

* commit '8246601a':
  riscv: tlb: fix __p*d_free_tlb()

Nathan Chancellor <nathan@kernel.org> says:

Eric reported that builds of LLVM with [1] (close to tip of tree) have
CONFIG_AS_HAS_OPTION_ARCH=n because the test for expected failure on
invalid input has started succeeding.

This Kconfig test was added because '.option arch' only causes an
assembler warning when it is unsupported, rather than a hard error,
which is what users of as-instr expect when something is unsupported.

This can be resolved by turning assembler warnings into errors with
'-Wa,--fatal-warnings' like we do with the compiler with '-Werror',
which is what the first patch does. The second patch removes the invalid
test, as the valid test is good enough with fatal warnings.

I have diffed several configurations for the different architectures
that use as-instr and I have found no issues.

Commit e4bb020f ("riscv: detect assembler support for .option arch")
added two tests, one for a valid value to '.option arch' that should
succeed and one for an invalid value that is expected to fail to make
sure that support for '.option arch' is properly detected because Clang
does not error when '.option arch' is not supported:

  $ clang --target=riscv64-linux-gnu -Werror -x assembler -c -o /dev/null <(echo '.option arch, +m')
  /dev/fd/63:1:9: warning: unknown option, expected 'push', 'pop', 'rvc', 'norvc', 'relax' or 'norelax'
  .option arch, +m
          ^
  $ echo $?
  0

Unfortunately, the invalid test started being accepted by Clang after
the linked llvm-project change, which causes CONFIG_AS_HAS_OPTION_ARCH
and configurations that depend on it to be silently disabled, even
though those versions do support '.option arch'.

The invalid test can be avoided altogether by using
'-Wa,--fatal-warnings', which will turn all assembler warnings into
errors, like '-Werror' does for the compiler:

  $ clang --target=riscv64-linux-gnu -Werror -Wa,--fatal-warnings -x assembler -c -o /dev/null <(echo '.option arch, +m')
  /dev/fd/63:1:9: error: unknown option, expected 'push', 'pop', 'rvc', 'norvc', 'relax' or 'norelax'
  .option arch, +m
          ^
  $ echo $?
  1

The as-instr macros have been updated to make use of this flag, so
remove the invalid test, which allows CONFIG_AS_HAS_OPTION_ARCH to work
for all compiler versions.

Certain assembler instruction tests may only induce warnings from the
assembler on an unsupported instruction or option, which causes as-instr
to succeed when it was expected to fail. Some tests workaround this
limitation by additionally testing that invalid input fails as expected.
However, this is fragile if the assembler is changed to accept the
invalid input, as it will cause the instruction/option to be unavailable
like it was unsupported even when it is.

Use '-Wa,--fatal-warnings' in the as-instr macro to turn these warnings
into hard errors, which avoids this fragility and makes tests more
robust and well formed.

The spare_init() calls memmap_populate() many times to create VA to PA
mapping for the VMEMMAP area, where all "struct page" are located once
CONFIG_SPARSEMEM_VMEMMAP is defined. These "struct page" are later
initialized in the zone_sizes_init() function. However, during this
process, no sfence.vma instruction is executed for this VMEMMAP area.
This omission may cause the hart to fail to perform page table walk
because some data related to the address translation is invisible to the
hart. To solve this issue, the local_flush_tlb_kernel_range() is called
right after the sparse_init() to execute a sfence.vma instruction for this
VMEMMAP area, ensuring that all data related to the address translation
is visible to the hart.
