X-Git-Tag: v2.6.34-rc1~285^2~17^2~3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d53a0d33bc3a50ea0e8dd1680a2e8435770b162a;p=pandora-kernel.git sh: PMB locking overhaul. This implements some locking for the PMB code. A high level rwlock is added for dealing with rw accesses on the entry map while a per-entry data structure spinlock is added to deal with the PMB entry changing out from underneath us.
