#     
#     Pull x86 fixes from Thomas Gleixner:
#      "A couple of x86 fixes which missed rc1 due to my stupidity:
#     
#        - Drop lazy TLB mode before switching to the temporary address space
#          for text patching.
#     
#          text_poke() switches to the temporary mm which clears the lazy mode
#          and restores the original mm afterwards. Due to clearing lazy mode
#          this might restore a already dead mm if exit_mmap() runs in
#          parallel on another CPU.
#     
#        - Document the x32 syscall design fail vs. syscall numbers 512-547
#          properly.
#     
#        - Fix the ORC unwinder to handle the inactive task frame correctly.
#     
#          This was unearthed due to the slightly different code generation of
#          gcc-10.
#     
#        - Use an up to date screen_info for the boot params of kexec instead
#          of the possibly stale and invalid version which happened to be
#          valid when the kexec kernel was loaded"
