Hello,

This is version 7 of the patches originally posted here:

v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-June/052157.html
v2: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-June/052559.html
v3: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-June/053252.html
v4: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-August/062305.html
v5: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/071909.html
v6: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/073054.html

The only change since v6 is that this code is now based on top of the latest idmap
patches, which I have posted separately.

Note that you will need abf015f0 ("Revert "ARM: 7098/1: kdump: copy kernel
relocation code at the kexec prepare stage") from rmk/fixes in order for this
code to operate correctly.

Cheers,

Will
