[SRU][J:gcp/gke, N:gcp/gke/gkeop][PATCH 0/5] IDPF: TX timeout and crash

[Ian Whitfield]

BugLink: https://bugs.launchpad.net/bugs/2093622

[Impact]
Google has requested a patchset to be backported to resolve an issue in
the IDPF module. The issue can lead to timeouts and potentially a system
crash.

[Fix]
Backport a patchset from linux upstream to all IDPF-enabled Google
kernels. This email is for Noble and Jammy, another email was sent for
Oracular.

[Test Plan]
Compile and boot tested.

[Regression Potential]
This is a medium size backport and affects several kernels. Because
these kernels have diverged from upstream, most of the patches did not
apply cleanly, which increases the chance of human error in the backport
process. Problems related to this fix could lead to further issues in
the Intel IDPF module, but there have been no changes to other drivers
or the core kernel.
