Subject: [PATCH 0/4] cputlb: add tlb_flush_other_cpu
Date: Tue, 25 Feb 2025 18:46:24 +0000	[thread overview]
Message-ID: <20250225184628.3590671-1-alex.bennee@linaro.org> (raw)

This is based on one of the fixes from Igor's series:

  20250207162048.1890669-1-imammedo@redhat.com

Rather than reverting the patch I cleaned up a couple of cases where
we either didn't need to do a flush or we could trivially defer to
when the CPU started running. For the other cases I introduced
tlb_flush_other_cpu() for users like reset and post migration. Any
other users wanting to do a cross-vcpu blat everything function like
tlb_flush() are almost certainly wanting to use a different more
targeted helper which still supports queuing async work.

Alex.

  target/ppc: drop ppc_tlb_invalidate_all from cpu_reset
  target/hppa: defer hppa_ptlbe until CPU starts running
  cputlb: introduce tlb_flush_other_cpu for reset use

  tcg:tlb: use tcg_debug_assert() in assert_cpu_is_self()
