Jammy update: v6.1.48 upstream stable release

Invalid
Status in linux-oem-6.1 source package in Jammy:
Fix Committed
Bug description:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The following upstream
stable patches should be included in the Ubuntu kernel:
v6.1.48 upstream stable release
from git://git.kernel.org/
Linux 6.1.48
x86/srso: Correct the mitigation status when SMT is disabled
