arm64: Fix race condition on PG_dcache_clean in __sync_icache_dcache() (2021-05-14 17:11:16 +0100)
---------------------------------------------------------------- arm64 fixes and cpucaps.h automatic generation:
- Generate cpucaps.h at build time rather than carrying lots of #defines. Merged at -rc1 to avoid some conflicts during the merging window.
- Initialise RGSR_EL1.SEED in __cpu_setup() as it may be left as 0 out of reset and the IRG instruction would not function as expected if only the architected pseudorandom number generator is implemented.
- Fix potential race condition in __sync_icache_dcache() where the PG_dcache_clean page flag is set before the actual cache maintenance.
- Fix header include in BTI kselftests.
