Merge branch 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6
* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6: [SPARC64]: Fix 'niu' complex IRQ probing. [SPARC64]: check fork_idle() error [SPARC64]: Temporary workaround for PCI-E slot on T1000. [SPARC64]: VIO device addition log message level is too high. [SPARC64]: Fix domain-services port probing. [SPARC64]: Don't use in/local regs for ldx/stx data in N1 memcpy.
