[PATCH RESEND 2/2] drivers/perf: Improve build test coverage

From: John Garry
Date: Fri Oct 01 2021 - 06:55:20 EST


Improve build test cover by allowing some drivers to build under
COMPILE_TEST where possible.

Some notes:
- Mostly a dependency on CONFIG_ACPI is not really required for only
building (but left untouched), but is required for TX2 which uses ACPI
functions which have no stubs
- XGENE required 64b dependency as it relies on some unsigned long perf
struct fields being 64b
- I don't see why TX2 requires NUMA to build, but left untouched
- Added an explicit dependency on GENERIC_MSI_IRQ_DOMAIN for
ARM_SMMU_V3_PMU, which is required for platform MSI functions
