#     Merge tag 'x86_urgent_for_v5.15_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Borislav Petkov:
#     
#      - Prevent a infinite loop in the MCE recovery on return to user space,
#        which was caused by a second MCE queueing work for the same page and
#        thereby creating a circular work list.
#     
#      - Make kern_addr_valid() handle existing PMD entries, which are marked
#        not present in the higher level page table, correctly instead of
#        blindly dereferencing them.
#     
#      - Pass a valid address to sanitize_phys(). This was caused by the
#        mixture of inclusive and exclusive ranges. memtype_reserve() expect
#        'end' being exclusive, but sanitize_phys() wants it inclusive. This
#        worked so far, but with end being the end of the physical address
#        space the fail is exposed.
#     
#      - Increase the maximum supported GPIO numbers for 64bit. Newer SoCs
#        exceed the previous maximum.
