arm64: fix !CONFIG_COMPAT build failures
Recent arm64 builds using CONFIG_ARM64_64K_PAGES are failing with:
arch/arm64/kernel/perf_regs.c: In function ‘perf_reg_abi’:
arch/arm64/kernel/perf_regs.c:41:2: error: implicit declaration of function ‘is_compat_thread’
arch/arm64/kernel/perf_event.c:1398:2: error: unknown type name ‘compat_uptr_t’
This is due to some recent arm64 perf commits with compat support:
commit 23c7d70d55c6d9:
ARM64: perf: add support for frame pointer unwinding in compat mode
commit 2ee0d7fd36a3f8:
ARM64: perf: add support for perf registers API
Those patches make the arm64 kernel unbuildable if CONFIG_COMPAT is not
defined and CONFIG_ARM64_64K_PAGES depends on !CONFIG_COMPAT. This patch
allows the arm64 kernel to build with and without CONFIG_COMPAT.
