[SRU Justification]
A new commit in the Jammy 5.15.0-29.30 kernel is causing a build failure for
the real-time kernel.
After a bisect, I found this commit is causing the real-time kernel build
failure:
dc66c1b8a2be1 ("x86/pkru: Remove useless include")
Commit dc66c1b8a2be1 was added in 5.16-rc1 and not cc'd to stable. It
was picked into Jammy to enable AMX support. See bug 1967750.
The following commit resolves this regression by fixing up the includes:
35fa745286ac4 ("x86/mm: Include spinlock_t definition in pgtable")
Commit 35fa745286ac4 was merged into mainline 5.17-rc1.
[Fix]
35fa745286ac4 ("x86/mm: Include spinlock_t definition in pgtable")
[Test case]
Kernel builds are now working after picking this commit.
[Regression potential]
Low. The new commit is just including a header file.
