Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: [MIPS] Fix EV64120 and Ocelot builds by providing a plat_timer_setup(). [MIPS] EV64120: Fix PCI interrupt allocation. [MIPS] Make irq number allocator generally available for fixing EV64120. [MIPS] EV64120: Fix timer initialization for HZ != 100. [MIPS] Ocelot 3: Fix MAC address detection after platform_device conversion. [MIPS] Ocelot C: Fix MAC address detection after platform_device conversion. [MIPS] SB1: On bootup only flush cache on local CPU. [MIPS] Ocelot 3: Fix large number of warnings. [MIPS] Ocelot C: Fix mapping of ioport address range. [MIPS] Ocelot C: Fix warning about missmatching format string. [MIPS] Ocelot C: fix eth registration after conversion to platform_device [MIPS] Ocelot C: Fix large number of warnings.
