Merge branch 'for-next/fixes' into for-next/core

Merge in for-next/fixes, as subsequent improvements to our early PI
code that disallow BSS exports depend on the 'arm64_use_ng_mappings'
fix here.

* for-next/fixes:
  arm64: cpufeature: Move arm64_use_ng_mappings to the .data section to prevent wrong idmap generation
  arm64: errata: Add missing sentinels to Spectre-BHB MIDR arrays
