Merge master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6 

* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6:
  [SERIAL] sunsu: Fix section mismatch warnings.
  [SPARC64]: pgtable_cache_init() should be __init.
  [SPARC64]: Fix section mismatch warnings in arch/sparc64/kernel/prom.c
  [SPARC64]: Fix section mismatch warnings in arch/sparc64/kernel/pci.c
  [SPARC64]: Fix section mismatch warnings in arch/sparc64/kernel/console.c
  [MM]: sparse_init() should be __init.
  [SPARC64]: Update defconfig.
  [VIDEO]: Add Sun XVR-2500 framebuffer driver.
  [VIDEO]: Add Sun XVR-500 framebuffer driver.
  [SPARC64]: SUN4U PCI-E controller support.
  [SPARC]: Fix comment typo in smp4m_blackbox_current().
  [SCSI] SUNESP: sun_esp.c needs linux/delay.h

Fix up conflict in arch/sparc64/mm/init.c manually due to removal of
pgtable_cache_init() through the -mm patches (even though that patch was
also by David ;)
