Subject: [PATCH v8 0/6] kexec fixes and soft restart code
Newsgroups: gmane.linux.ports.arm.kernel
Date: Thursday 8th December 2011 19:03:17 UTC (over 4 years ago)
Hello,

This is version 8 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
v7: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/074338.html

There are a few small changes since v7:

 - Fixed a warning in the stack declaration from an implicit u64* -> u32*
cast
 - Rebased onto rmk/devel-stable, which now includes my idmap patches
 - Merged in the outer_disable patch with the soft_restart patch as it
   didn't warrant a separate commit.

I'm pretty happy with these patches, but I appreciate there is already a
lot
queued for 3.3. Russell - would you rather I held fire on these for the
time
being (the downside being that soft reboot is broken for a bit longer)?

Cheers,

Will
