Pull arm64 fixes from Catalin Marinas:
- clear buffers allocated with FORCE_CONTIGUOUS explicitly until the
CMA code honours __GFP_ZERO
- notrace annotation for secondary_start_kernel()
- use early_param() instead of __setup() for "kpti=" as it is needed
for the cpufeature callback remapping swapper to non-global mappings
- ensure writes to swapper are ordered wrt subsequent cache maintenance
in the kpti non-global remapping code
