[PPC] 8xx: Fix r3 trashing due to 8MB TLB page instantiation
Instantiation of 8MB pages on the TLB cache for the kernel static
mapping trashes r3 register on !CONFIG_8xx_CPU6 configurations.
This ensures r3 gets saved and restored.
This has been posted to linuxppc-embedded by Marcelo Tosatti
<[EMAIL PROTECTED]>, but only an incomplete version of the patch
has been applied in c51e078f82096a7d35ac8ec2416272e843a0e1c4.
This patch adds the rest of the fix.
