Subject: [patch 0/4] x86/kaiser: Boot time disabling and debug support
Date: Sun, 26 Nov 2017 18:55:38 +0100 [thread overview]
Message-ID: <20171126175538.841453476@linutronix.de> (raw)
This patch series applies on top of
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/mm
It contains the following updates:
- Get rid of the compile time PAGE_GLOBAL disabling
- Add debug support for WX mappings in the KAISER shadow table
- Provide debug files to dump the kernel and the user page table for the
current task.
- Add a boot time switch to disable KAISER. This does not yet take care of
the 8k PGD allocations, but that can be done on top.
Thanks,
tglx
