Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle: "misc fixes some of which are also applicable to 3.3 and removal of an unused function. This has been sitting in -next for ages with no complaints. Also there are no known regressions due to these patches" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Remove get_current_pgd(). MIPS: ath79: fix AR933X WMAC reset code MIPS: JZ4740: Fix the JZ4740_IRQ_DMA macro MIPS: Use set_current_blocked() and block_sigmask()
