Merge tag 'x86_urgent_for_v5.19_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov:
- Prepare for and clear .brk early in order to address XenPV guests
failures where the hypervisor verifies page tables and uninitialized
data in that range leads to bogus failures in those checks
- Add any potential setup_data entries supplied at boot to the identity
pagetable mappings to prevent kexec kernel boot failures. Usually,
this is not a problem for the normal kernel as those mappings are
part of the initially mapped 2M pages but if kexec gets to allocate
the second kernel somewhere else, those setup_data entries need to be
mapped there too.
- Fix objtool not to discard text references from the __tracepoints
section so that ENDBR validation still works
- Correct the setup_data types limit as it is user-visible, before 5.19
releases
