linux-toradex.git/arch/arm/mm/cache-v7m.S, branch v5.1 Linux kernel for Apalis and Colibri modules ARM: 8815/1: V7M: align v7m_dma_inv_range() with v7 counterpart 2018-12-04T22:38:33+00:00 Vladimir Murzin vladimir.murzin@arm.com 2018-11-23T11:25:21+00:00 3d0358d0ba048c5afb1385787aaec8fa5ad78fcc Chris has discovered and reported that v7_dma_inv_range() may corrupt memory if address range is not aligned to cache line size. Since the whole cache-v7m.S was lifted form cache-v7.S the same observation applies to v7m_dma_inv_range(). So the fix just mirrors what has been done for v7 with a little specific of M-class.

Fix typos and add the following to the scripts/spelling.txt:

  swith||switch
  swithable||switchable
  swithed||switched
  swithing||switching

While we are here, fix the "update" to "updates" in the touched hunk in
drivers/net/wireless/marvell/mwifiex/wmm.c.
