Linus Torvalds ed8780e3f2 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 GCC10.
 
   - 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.
