Merge master.kernel.org:/pub/scm/linux/kernel/git/lethal/sh-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/lethal/sh-2.6: (26 commits) sh: remove dead config symbols from SH code sh: Kill off broken snapgear ds1302 code. sh: Add a dummy vga.h. rtc: rtc-sh: Zero out tm value for invalid rtc states. rtc: sh-rtc: Handle rtc_device_register() failure properly. sh: Fix heartbeart on Solution Engine series sh: Remove SCI_NPORTS from sh-sci.h sh: Fix up PAGE_KERNEL_PCC() for nommu. sh: hs7751rvoip: Kill off dead IPR IRQ mappings. sh: hs7751rvoip: irq.c needs linux/interrupt.h. sh: Kill off __{copy,clear}_user_page(). sh: Optimized copy_{to,from}_user_page() for SH-4. sh: Wire up clear_user_highpage(). sh: Kill off the remaining ST40 cruft. superhyway: Handle device_register() retval properly. sh: kgdb sysrq depends on magic sysrq. sh: Add -Werror for clean directories. sh: Fix up kgdb build with modular sh-sci. sh: Export __{s,u}divsi3_i4i on all CPUs. sh: Fix up kgdb-on-NMI branch target. ...
