Just a few more Niagara T3 refinements as well as several
bug fixes, including:
1) On sun4v we need to access the TSB using physical addresses otherwise
we can read/write different data than what the hypervisor and/or
the hardware TSB walker does.
2) sparc32 __atomic_add_unless return value needs correction, from
Josip Rodin.
3) Sun4v cpu mondo queue sizes could be way too large, and we'd fail
to allocate them because the page allocation order would exceed
MAX_ORDER. Set a sane cap to fix the problem.
4) Sam Ravnborg's patch to use kbuild-generic.
5) Use the hypervisor interface to set the 'reboot-cmd' variable so
that rebooting into the correct image works even if the service
processor is dead or in degraded mode.
Please pull, thanks a lot!
