slb_flush_and_rebolt() is misleading, it is called in virtual mode, so
it can not possibly change the stack, so it should not be touching the
shadow area. And since vmalloc is no longer bolted, it should not
change any bolted mappings at all.
Change the name to slb_flush_and_restore_bolted(), and have it just
load the kernel stack from what's currently in the shadow SLB area.

binutils >= 2.26 now warns about misuse of register expressions in
assembler operands that are actually literals, for example:
arch/powerpc/kernel/entry_64.S:535: Warning: invalid register expression
In practice these are almost all uses of r0 that should just be a
literal 0.

Currently, when not in hypervisor mode the kernel
Oopses during suspend or hibernation when accessing
the SDR1 register, because it is only available
in hypervisor mode. Access to it needs to be
protected in BEGIN/END_FW_FTR_SECTION.

Update the 64-bit hibernation code to support Book E CPUs.
Some registers and instructions are not defined for Book3e
(SDR reg, tlbia instruction).
SDR: Storage Description Register. Book3S and Book3E have different
address translation mode, we do not need HTABORG & HTABSIZE to
translate virtual address to real address.
More registers are saved in BookE-64bit.(TCR, SPRG1)

Powermac G5 suspend to disk implementation. The code is platform
agnostic but only tested on powermac, no other 64-bit powerpc
machines.
Because nvidiafb still breaks suspend I have marked it EXPERIMENTAL on
powermac and because I can't test it and some lowlevel code will need
changes it is BROKEN on all other 64-bit platforms.
