Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (53 commits) [MIPS] sparsemem: fix crash in show_mem [MIPS] vr41xx: Update workpad setup function [MIPS] vr41xx: Update e55 setup function [MIPS] vr41xx: Removed old v2.4 VRC4173 driver [MIPS] vr41xx: Move IRQ numbers to asm-mips/vr41xx/irq.h [MIPS] MIPSsim: Build fix, rename sim_timer_setup -> plat_timer_setup. [MIPS] Remove unused code. [MIPS] IP22 Fix brown paper bag in RTC code. [MIPS] Atlas, Malta, SEAD: Don't disable interrupts in mips_time_init(). [MIPS] Replace board_timer_setup function pointer by plat_timer_setup. [MIPS] Nuke redeclarations of board_time_init. [MIPS] Remove redeclarations of setup_irq(). [MIPS] Nuke redeclarations of board_timer_setup. [MIPS] Print out TLB handler assembly for debugging. [MIPS] SMTC: Reformat to Linux style. [MIPS] MIPSsim: Delete redeclaration of ll_local_timer_interrupt. [MIPS] IP27: Reformatting. [MIPS] IP27: Invoke setup_irq for timer interrupt so proc stats will be shown. [MIPS] IP27: irq_chip startup method returns unsigned int. [MIPS] IP27: struct irq_desc member handler was renamed to chip. ...
