Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (21 commits) MIPS: Alchemy: PB1200: use SMC91X platform data. MIPS: Alchemy: MIPS hazard workarounds are not required. MIPS: Alchemy: provide cpu feature overrides. MIPS: Alchemy: unify CPU model constants. MIPS: Make a needlessly global symbol static in arch/mips/kernel/smp.c MIPS: Fix global namespace pollution in arch/mips/kernel/smp-up.c MIPS: Malta: make a needlessly global integer variable static MIPS: Use BUG_ON() where possible. MIPS: Convert obsolete irq_desc_t to struct irq_desc MIPS: Enable GENERIC_HARDIRQS_NO__DO_IRQ for all platforms MIPS: EMMA2RH: Set UART mapbase MIPS: EMMA2RH: Use set_irq_chip_and_handler_name MIPS: EMMA2RH: Use handle_edge_irq() handler for GPIO interrupts MIPS: Mark Eins: Fix cascading interrupt dispatcher MIPS: Au1000: convert to using gpiolib MIPS: Stop using <asm-generic/int-l64.h>. MIPS: Cavium: Add -Werror MIPS: Makefile: Add simple make install target. MIPS: Compat: Zero upper 32-bit of offset_high and offset_low. MIPS: __raw_spin_lock() may spin forever on ticket wrap. ...
