Merge master.kernel.org:/pub/scm/linux/kernel/git/willy/parisc-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/willy/parisc-2.6: (41 commits) [PARISC] Kill wall_jiffies use [PARISC] Honour "panic_on_oops" sysctl [PARISC] Fix fs/binfmt_som.c [PARISC] Export clear_user_page to modules [PARISC] Make DMA routines more stubby [PARISC] Define pci_get_legacy_ide_irq [PARISC] Fix CONFIG_DEBUG_SPINLOCK [PARISC] Fix HPUX compat compile with current GCC [PARISC] Fix iounmap compile warning [PARISC] Add support for Quicksilver AGPGART [PARISC] Move LBA and SBA register defines to the common ropes.h [PARISC] Create shared <asm/ropes.h> header [PARISC] Stash the lba_device in its struct device drvdata [PARISC] Generalize IS_ASTRO et al to take a parisc_device like [PARISC] Pretty print the name of the lba type on kernel boot [PARISC] Remove some obsolete comments and I checked that Reo is similar to Ike [PARISC] Add hardware found in the rp8400 [PARISC] Allow nested interrupts [PARISC] Further updates to timer_interrupt() [PARISC] remove halftick and copy clocktick to local var (gcc can optimize usage) ...
