Linus,
Please pull the latest x86-asm-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-asm-for-linus
# HEAD: 7457c0da024b181a9143988d740001f9bc98698d x86/alternatives: Add int3_emulate_call() selftest
Most of the changes relate to Peter Zijlstra's cleanup of ptregs
handling, in particular the i386 part is now much simplified and
standardized - no more partial ptregs stack frames via the esp/ss oddity.
This simplifies ftrace, kprobes, the unwinder, ptrace, kdump and kgdb.
There's also a CR4 hardening enhancements by Kees Cook, to make the
generic platform functions such as native_write_cr4() less useful as ROP
gadgets that disable SMEP/SMAP. Also protect the WP bit of CR0 against
similar attacks.
The rest is smaller cleanups/fixes.
Thanks,
Ingo
