powerpc/64s: Remove TM from Power10 features
Browse files Browse the repository at this point in the history
[ Upstream commit ec613a5 ]

ISA v3.1 removes transactional memory and hence it should not be present
in cpu_features or cpu_user_features2. Remove CPU_FTR_TM_COMP from
CPU_FTRS_POWER10. Remove PPC_FEATURE2_HTM_COMP and
PPC_FEATURE2_HTM_NOSC_COMP from COMMON_USER2_POWER10.

Fixes: a3ea40d ("powerpc: Add POWER10 architected mode")
