Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS update from Ralf Baechle: - Fix a build error if <linux/printk.h> is included without <linux/linkage.h> having been included before. - Cleanup and fix the damage done by the generic idle loop patch. - A kprobes fix that brings the MIPS code in line with what other architectures are for quite a while already. - Wire up the native getdents64(2) syscall for 64 bit - for some reason it was only for the compat ABIs. This has been reported to cause an application issue. This turned out bigger than I meant but the wait instruction support code was driving me nuts. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: N64: Wire getdents64(2) kprobes/mips: Fix to check double free of insn slot MIPS: Idle: Break r4k_wait into two functions and fix it. MIPS: Idle: Do address fiddlery in helper functions. MIPS: Idle: Consolidate all declarations in <asm/idle.h>. MIPS: Idle: Don't call local_irq_disable() in cpu_wait() implementations. MIPS: Idle: Re-enable irqs at the end of r3081, au1k and loongson2 cpu_wait. MIPS: Idle: Make call of function pointer readable. MIPS: Idle: Consistently reformat inline assembler. MIPS: Idle: cleaup SMTC idle hook as per Linux coding style. MIPS: Consolidate idle loop / WAIT instruction support in a single file. MIPS: clock.h: Remove declaration of cpu_wait. Add include dependencies to <linux/printk.h>. MIPS: Rewrite pfn_valid to work in modules, too.
