The following changes since commit 5b47348fc0b18a78c96f8474cc90b7525ad1bbfe: arm64/mm: fix incorrect file_map_count for non-leaf pmd/pud (2022-11-18 19:31:54 +0000) 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 b7d9aae404841d9999b7476170867ae441e948d2: Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()" (2022-12-06 17:30:39 +0000) ---------------------------------------------------------------- Revert the dropping of the cache invalidation from the arm64 arch_dma_prep_coherent() as it caused a regression in the qcom_q6v5_mss remoteproc driver. The driver is already buggy but the original arm64 change made the problem obvious. The change will be re-introduced once the driver is fixed. ---------------------------------------------------------------- Will Deacon (1): Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()" arch/arm64/mm/dma-mapping.c | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-)
