Subject: [GIT PULL] arm64 fix/revert for 6.1

Hi Linus,

Please pull the revert below. The qcom driver fix is being worked on but
not in time for 6.1, so revert the arm64 change that highlighted the
issue.

Thanks.

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)

  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.
