[PATCH 0/3] support FEAT_MTE_TAGGED_FAR feature

[Yeoreum Yun]

The FEAT_MTE_TAGGED_FAR feature provides support for
reporting all non-address bits during a synchronous MTE tag check fault.

This patchset extends the reporting tag to include
not only the memory tag (logical tag) but also the address tag via
si_addr when FEAT_MTE_TAGGED_FAR feature is supported.

Yeoreum Yun (3):
  arm64: add FEAT_MTE_TAGGED_FAR feature
  arm64/mm/fault: use original FAR_EL1 value when ARM64_MTE_FAR is
    supported
  Documentation/arm64: reflects FEAT_MTE_TAGGED_FAR description
