* [POWERPC] Use 1TB segmentsPaul Mackerras2007-10-121-16/+18
| | | | | | | | | | | | | | | | | | | | This makes the kernel use 1TB segments for all kernel mappings and for user addresses of 1TB and above, on machines which support them (currently POWER5+, POWER6 and PA6T). We detect that the machine supports 1TB segments by looking at the ibm,processor-segment-sizes property in the device tree. We don't currently use 1TB segments for user addresses < 1T, since that would effectively prevent 32-bit processes from using huge pages unless we also had a way to revert to using 256MB segments. That would be possible but would involve extra complications (such as keeping track of which segment size was used when HPTEs were inserted) and is not addressed here. Parts of this patch were originally written by Ben Herrenschmidt. Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Celleb: improve MMU hashtable lockingAkira Iguchi2007-02-131-11/+8
| | | | | | | | | | Disabling IRQ is required only in invalidation. This changes "spin_lock_irqsave" to "spin_lock" in other ops.
