Hi!

This is an updated version of the guard page series:

V1: https://lkml.kernel.org/r/20190331214020.836098943@linutronix.de
V2: https://lkml.kernel.org/r/20190405150658.237064784@linutronix.de

Changes vs. V2:

- Fixed the broken stack trace storage in slub

- Adjust the guard page ordering and fix the top macro (Sean)

- Fix an off by one in the debug stack check (Sean)

- Rename ISTACK_ prefix to ESTACK_ (Josh)

- Collected Acked/Reviewed-by tags

The lot is also available from tip:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/stackguards

310a7f5b0b42 ("x86/irq/64: Remove stack overflow debug code")

Thanks,

tglx
