[patch 0/4] x86/kaiser: Boot time disabling and debug support

[Thomas Gleixner]

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
