Kristina Martsenko b0fe378674 arm64: cpufeature: Fix CLRBHB and BC detection ... commit 479965a2b7 upstream. ClearBHB support is indicated by the CLRBHB field in ID_AA64ISAR2_EL1. Following some refactoring the kernel incorrectly checks the BC field instead. Fix the detection to use the right field. (Note: The original ClearBHB support had it as FTR_HIGHER_SAFE, but this patch uses FTR_LOWER_SAFE, which seems more correct.) Also fix the detection of BC (hinted conditional branches) to use FTR_LOWER_SAFE, so that it is not reported on mismatched systems. Fixes: 356137e68a ("arm64/sysreg: Make BHB clear feature defines match the architecture") Fixes: 8fcc8285c0 ("arm64/sysreg: Convert ID_AA64ISAR2_EL1 to automatic generation") Cc: stable@vger.kernel.org Signed-off-by: Kristina Martsenko <kristina.martsenko@arm.com> Reviewed-by: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/20230912133429.2606875-1-kristina.martsenko@arm.com Signed-off-by: Will Deacon <will@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2023-10-10 22:00:37 +02:00
