[PATCH v1] perf: starfive: fix 64-bit only COMPILE_TEST condition

[PATCH v1] perf: starfive: fix 64-bit only COMPILE_TEST condition

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

ARCH_STARFIVE is not restricted to 64-bit platforms, so while Will's
addition of a 64-bit only condition satisfied the build robots doing
COMPILE_TEST builds, Palmer ran into the same problems with writeq()
being undefined during regular rv32 builds.

Promote the dependency on 64-bit to its own `depends on` so that the
driver can never be included in 32-bit builds.

Reported-by: Palmer Dabbelt <palmer@rivosinc.com>
Fixes: c2b24812f7bc ("perf: starfive: Add StarLink PMU support")
Fixes: f0dbc6d0de38 ("perf: starfive: Only allow COMPILE_TEST for 64-bit architectures")

Thanks guys, I don't know what a starfive is so sorry for not spotting
this when I noticed the build failure on arm64.

Acked-by: Will Deacon <will@kernel.org>

Catalin -- please can you pick this into the arm64 fixes branch for -rc1?

Cheers,

Will

It's a bit like a starfish, I guess you've seen them in sealife? Or
maybe some David Attenborough show?

Applied to arm64 (for-next/core), thanks!
