| |
This series collects a number of small cleanups to the signal handling code which removes redundant validation of size information and avoids reading the same data from userspace twice.
There are some overlaps with both the TPIDR2 signal handling and SME2 serieses which are also in flight, applying this will require adjustments in those serieses and vice versa.
Changes in v3: - Rebase onto arm64/for-next/core, updating for the addition of ZT and TPIDR2 signal frames. - Link to v2: https://lore.kernel.org/r/20221212-arm64-signal-cleanup-v2-0-14a8f3e088b7@kernel.org v2: - Rebase onto v6.2-rc1
Signed-off-by: Mark Brown <broonie@kernel.org> --- Mark Brown (7): arm64/signal: Don't redundantly verify FPSIMD magic arm64/signal: Remove redundant size validation from parse_user_sigframe() arm64/signal: Make interface for restore_fpsimd_context() consistent arm64/signal: Avoid rereading context frame sizes arm64/signal: Only read new data when parsing the SVE context arm64/signal: Only read new data when parsing the ZA context arm64/signal: Only read new data when parsing the ZT context
