Subject: [PATCH 0/4] arm64: Cleanup ioremap() and support ioremap_prot()
Date: Wed, 27 Apr 2022 20:14:09 +0800	[thread overview]
Message-ID: <20220427121413.168468-1-wangkefeng.wang@huawei.com> (raw)

Let's arm64 use GENERIC_IOREMAP to cleanup code, and
support ioremap_prot()/HAVE_IOREMAP_PROT, which could
enable generic_access_phys().

Kefeng Wang (4):
  mm: ioremap: Setup phys_addr of struct vm_struct
  mm: ioremap: Add arch_ioremap/iounmap_check()
  arm64: mm: Convert to GENERIC_IOREMAP
  arm64: Add HAVE_IOREMAP_PROT support
