* master.kernel.org:/home/rmk/linux-2.6-arm: [ARM] 3030/2: fix permission check in the obscur cmpxchg syscall [ARM] nommu: rename compressed/head.S symbols to a new style [ARM] select TLS_REG_EMUL and NEEDS_SYSCALL_FOR_CMPXCHG [ARM] nommu: Move hardware page table definitions to pgtable-hwdef.h [ARM] Move read of processor ID out of lookup_processor_type() [ARM] Fix typo in tlbflush.h [ARM] noMMU: removes TLB codes in nommu mode [ARM] noMMU: block sys_fork in nommu mode [ARM] 3399/1: Fix link problem when CONFIG_PRINTK is disabled [ARM] 3398/1: Fix the VFP registers loading/storing base address [ARM] 3397/1: AT91RM9200 Header update [ARM] 3385/1: Battery support for sharp zaurus sl-5500 (collie) [ARM] SMP: don't set cpu_*_map in smp_prepare_boot_cpu include/linux/clk.h is betraying its ARM origins [ARM] Move enable_irq and disable_irq to assembler.h [ARM] 3391/1: use PLAT8250_DEV_PLATFORM{,1} for platform device id instead of 0/1
