Subject: [PATCH v3 0/6] Implement byteswap and update references
Date: Tue, 10 May 2022 06:15:18 -0400	[thread overview]
Message-ID: <cover.1652170719.git.lin.liu@citrix.com> (raw)


The swab() is massively over complicated
Simplify it with compiler builtins and fallback to plain C function
if undefined.
Update components to switch to this new swap bytes.

Lin Liu (6):
  xen: implement byteswap
  crypto/vmac: Simplify code with byteswap
  arm64/find_next_bit: Remove ext2_swab()
  xen: Switch to byteswap
  byteorder: Remove byteorder
  tools: Remove unnecessary header
