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 wreckage after removal of tickadj; convert to GENERIC_TIME. [MIPS] DECstation defconfig update [MIPS] Fix size of zones_size and zholes_size array [MIPS] BCM1480: Mask pending interrupts against c0_status.im. [MIPS] SB1250: Interrupt handler fixes [MIPS] Remove IT8172-based platforms, ITE 8172G and Globespan IVR support. [MIPS] Remove Atlas and SEAD from feature-removal-schedule. [MIPS] Remove Jaguar and Ocelot family from feature list. [MIPS] BCM1250: TRDY timeout tweaks for Broadcom SiByte systems [MIPS] Remove dead DECstation boot code [MIPS] Let gcc align 'struct pt_regs' on 8 bytes boundary
