Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (49 commits) MIPS: RB532: provide GPIO_BUILTIN_NR and irq_to_gpio/gpio_to_irq MIPS: Move ptrace prototypes to ptrace.h MIPS: Ptrace support for HARDWARE_WATCHPOINTS MIPS: Scheduler support for HARDWARE_WATCHPOINTS. MIPS: Watch exception handling for HARDWARE_WATCHPOINTS. MIPS: Probe watch registers and report configuration. MIPS: Add HARDWARE_WATCHPOINTS definitions and support code. MIPS: Add HARDWARE_WATCHPOINTS configure option. MIPS: Replace use of <asm-generic/uaccess.h> with native implementations. MIPS: TXx9: Add TX4939 ATA support (v2) MIPS: Rewrite spinlocks to ticket locks. MIPS: IP checksums: Optimize adjust of sum on buffers of odd alignment. MIPS: IP checksums: Remove unncessary .set pseudos MIPS: IP checksums: Remove unncessary folding of sum to 16 bit. MIPS: Move headfiles to new location below arch/mips/include MIPS: Alchemy: rename directory MIPS: Optimize get_user and put_user for 64-bit MIPS: TXx9: Implement prom_free_prom_memory MIPS: TXx9: Add RBTX4939 board support MIPS: TXx9: Add TX4939 SoC support ...
