Subject: [GIT PULL] x86/entry changes for v5.4

Linus,

Please pull the latest x86-entry-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-entry-for-linus

   # HEAD: 6365b842aae4490ebfafadfc6bb27a6d3cc54757 x86/syscalls: Split the x32 syscalls into their own table

This tree contains x32 and compat syscall improvements, the biggest one 
of which splits x32 syscalls into their own table, which allows new 
syscalls to share the x32 and x86-64 number - which turns the 512-547 
special syscall numbers range into a legacy wart that won't be extended 
going forward.

 Thanks,

	Ingo

------------------>
Andy Lutomirski (4):
      x86/syscalls: Make __X32_SYSCALL_BIT be unsigned long
      x86/syscalls: Use the compat versions of rt_sigsuspend() and rt_sigprocmask()
      x86/syscalls: Disallow compat entries for all types of 64-bit syscalls
      x86/syscalls: Split the x32 syscalls into their own table
