Public bug reported:
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
objtool/x86: Fixup frame-pointer vs rethunk
x86/retpoline,kprobes: Fix position of thunk sections with CONFIG_LTO_CLANG
x86/srso: Disable the mitigation on unaffected configurations
x86/CPU/AMD: Fix the DIV(0) initial fix attempt
x86/retpoline: Don't clobber RFLAGS during srso_safe_ret()
x86/static_call: Fix __static_call_fixup()
x86/srso: Explain the untraining sequences a bit more
x86/cpu: Cleanup the untrain mess
x86/cpu: Rename srso_(.*)_alias to srso_alias_\1
x86/cpu: Rename original retbleed methods
x86/cpu: Clean up SRSO return thunk mess
x86/alternative: Make custom return thunk unconditional
x86/cpu: Fix up srso_safe_ret() and __x86_return_thunk()
x86/cpu: Fix __x86_return_thunk symbol type
