This bug is awaiting verification that the linux-aws-
fips/5.15.0-1056.61+fips1 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-jammy-linux-aws-fips' to
'verification-done-jammy-linux-aws-fips'. If the problem still exists,
change the tag 'verification-needed-jammy-linux-aws-fips' to
'verification-failed-jammy-linux-aws-fips'.


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:
  AWS: arm64: pauth: don't sign leaf functions

Status in linux-aws package in Ubuntu:
  Fix Released
Status in linux-aws source package in Jammy:
  Fix Released

Bug description:
  SRU Justification

  [Impact]

  From our experiments, we found that not signing leaf functions on AWS
  Graviton instances helps improve application performance. We would
  like to have the patch
  
https://github.com/torvalds/linux/commit/c68cf5285e1896a2b725ec01a1351f08610165b8
  backported to Ubuntu 5.15, 5.19 and 6.2 kernels. We saw some of these
  performance improvements: NGINX 1%, MySQL 2%, PyTorch 2%

  [Test Plan]

  AWS tested.

  [Regression Potential]

  Arm64 binaries may not work correctly.
