Another week, another version. Change log below.
I'll drop this into -next now, and see what happens.
* From v3 [3]:
- Renamed trap_group to cgt_group_id (Eric)
- Plenty of comment rework (Eric)
- Fix HCR_EL2.FIEN handling (Miguel)
- Fix missing validation of last MCB entry (Miguel)
- Fix instance of recursive MCB (Jing)
- Handle error return from xa_store()/xa_range_store() (Jing)
- Propagate error generated from populate_nv_trap_config() (Jing)
- Added more consistency checks for sysregs and trap bits
- Added a line number entry, which is useful for debugging
overlapping entries.
- Fixed duplicate entries for SP_EL1, DBGDTRRX_EL0 and SCXTNUM_EL0
- Correctly handle fine grained trapping for ERET
- Collected RBs, with thanks
* From v2 [2]:
- Another set up fixups thanks to Oliver, Eric and Miguel: TRCID
bits, duplicate encodings, sanity checking, error handling at boot
time, spelling mistakes...
- Split the HFGxTR_EL2 patch in two patches: one that provides the
FGT infrastructure, and one that provides the HFGxTR_EL2 traps. It
makes it easier to review and matches the rest of the series.
- Collected RBs, with thanks
* From v1 [1]:
- Lots of fixups all over the map (too many to mention) after Eric's
fantastic reviewing effort. Hopefully the result is easier to
understand and less wrong
- Amended Mark's patch to use the ARM64_CPUID_FIELDS() macro
- Collected RBs, with thanks.
