This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'. If the problem still exists,
change the tag 'verification-needed-xenial' to 'verification-failed-
xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  sha1_ce and sha2_ce modules no longer load on arm64

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Xenial:
  Fix Committed

Bug description:
  [Impact]
  The sha{1,2}_ce modules no longer load on arm64, preventing the use of the 
hardware accelerated ARMv8 crypto extensions for SHA1, SHA-224/SHA-256.

  [Test Case]
  sudo modprobe sha1_ce
  Currently fails:
  [   33.838295] module sha1_ce: unsupported RELA relocation: 275

  [Fix]
  For now I suggest reverting the commit that introduced the regression:
  2675530a1d16 crypto: arm64/sha - avoid non-standard inline asm tricks

  [Where problems could occur]
  The purpose of this commit appears to be better compatibility with Clang, so 
regressions are likely to be with any developers using Clang with our kernel 
source.
