* sh: Replace unsafe manipulation of MMUCRMatt Fleming2010-03-23
| | | | | | | | | | | | | | Setting the TI in MMUCR causes all the TLB bits in MMUCR to be cleared. Unfortunately, the TLB wired bits are also cleared when setting the TI bit, causing any wired TLB entries to become unwired. Use local_flush_tlb_all() which implements TLB flushing in a safer manner by using the memory-mapped TLB registers. As each CPU has its own PMB the modifications in pmb_init() only affect the local CPU, so only flush the local CPU's TLB.

* sh: Mass ctrl_in/outX to __raw_read/writeX conversion.Paul Mundt2010-01-25
| | | | | | | | | | | The old ctrl in/out routines are non-portable and unsuitable for cross-platform use. While drivers/sh has already been sanitized, there is still quite a lot of code that is not. This converts the arch/sh/ bits over, which permits us to flag the routines as deprecated whilst still building with -Werror for the architecture code, and to ensure that future users are not added.
