Thanks. The following changes since commit 65266a7c6abfa1ad915a362c41bf38576607f1f9: Merge remote-tracking branch 'tip/sched/arm64' into for-next/core (2021-08-31 09:10:00 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-fixes for you to fetch changes up to 85f58eb1889826b9745737718723a80b639e0fbd: arm64: kdump: Skip kmemleak scan reserved memory for kdump (2021-09-10 11:58:59 +0100) ---------------------------------------------------------------- arm64 fixes: - Limit the linear region to 51-bit when KVM is running in nVHE mode otherwise, depending on the placement of the ID map, kernel-VA to hyp-VA translations may produce addresses that either conflict with other HYP mappings or generate addresses outside of the 52-bit addressable range. - Instruct kmemleak not to scan the memory reserved for kdump as this range is removed from the kernel linear map and therefore not accessible. ---------------------------------------------------------------- Ard Biesheuvel (1): arm64: mm: limit linear region to 51 bits for KVM in nVHE mode Chen Wandun (1): arm64: kdump: Skip kmemleak scan reserved memory for kdump arch/arm64/mm/init.c | 22 +++++++++++++++++++++- 1 file changed, 21 insertions(+), 1 deletion(-)
