* | MIPS: Idle: Break r4k_wait into two functions and fix it.Ralf Baechle2013-05-21
| | | | | | | | | | | | | | | | | | | | | | | | local_irq_enable() may expand into very different code, so it rather should stay in C. Also this keeps the assembler code size constant which keeps the rollback code simple. So it's best to split r4k_wait into two parts, one C and one assembler. Finally add the local_irq_enable() to r4k_wait to ensure the WAIT instruction in __r4k_wait() will work properly. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

While MIPS has announced hardware virtualization extensions this KVM extension uses trap and emulate mode for virtualization of MIPS32. More KVM work to add support for VZ hardware virtualizaiton extensions and MIPS64 will probably already be merged for 3.11. Most of this has been sitting in -next for a long time. All defconfigs have been build or run time tested except three for which fixes are being sent by other maintainers.
