Subject: [GIT pull] x86/entry for v5.7
Linus,
please pull the latest x86/entry branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-entry-2020-03-30
up to: 290a4474d019: x86/entry: Fix build error x86 with !CONFIG_POSIX_TIMERS
x86 entry code updates:
- 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.
Thanks,
tglx
