    Linus Torvalds authored
    Pull x86 entry code updates from Thomas Gleixner:
    
     - Convert the 32bit syscalls to be pt_regs based which removes the
       requirement to push all 6 potential arguments onto the stack and
       consolidates the interface with the 64bit variant
    
     - The first small portion of the exception and syscall related entry
       code consolidation which aims to address the recently discovered
       issues vs. RCU, int3, NMI and some other exceptions which can
       interrupt any context. The bulk of the changes is still work in
       progress and aimed for 5.8.
    
     - A few lockdep namespace cleanups which have been applied into this
       branch to keep the prerequisites for the ongoing work confined.
