Subject: [GIT PULL] x86/entry changes for v6.8

Linus,

Please pull the latest x86/entry git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-entry-2024-01-08

   # HEAD: 1e4d3001f59fb7a9917cb746544b65e616b5f809 x86/entry: Harden return-to-user

x86/entry changes for v6.8:

 - Optimize common_interrupt_return()

 - Harden the return-to-user code by making a CONFIG_DEBUG_ENTRY=y
   check unconditional & moving it closer to the IRET.

 Thanks,

	Ingo
