Subject: [PATCH 0/3] support FEAT_MTE_TAGGED_FAR feature
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
