Subject: [PATCH 0/9] lib/crypto: arm64: Remove obsolete chunking logic
Date: Tue, 31 Mar 2026 17:05:39 -0700 [thread overview]
Message-ID: <20260401000548.133151-1-ebiggers@kernel.org> (raw)
Since commit aefbab8e77eb ("arm64: fpsimd: Preserve/restore kernel mode
NEON at context switch"), kernel-mode NEON sections have been
preemptible on arm64. And since commit 7dadeaa6e851 ("sched: Further
restrict the preemption modes"), voluntary preemption is no longer
supported on arm64 either. Therefore, there's no longer any need to
limit the length of kernel-mode NEON sections on arm64.
This series simplifies the code in lib/crypto/arm64/ accordingly by
using longer kernel-mode NEON sections instead of multiple shorter ones.
This series is targeting libcrypto-next.
