This patch adds a generic implementation of ioremap_page_range() in lib/ioremap.c based on the i386 implementation. It differs from the i386 version in the following ways: * The PTE flags are passed as a pgprot_t argument and must be determined up front by the arch-specific code. No additional PTE flags are added. * Uses set_pte_at() instead of set_pte() [bunk@stusta.de: warning fix] ]dhowells@redhat.com: nommu build fix] Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Cc: Russell King <rmk@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Andi Kleen <ak@suse.de> Cc: <linux-m32r@ml.linux-m32r.org> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Kyle McMartin <kyle@parisc-linux.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
