[Linux-mips-commits]CVS: linux/include/asm-generic mmu.h,NONE,1.1

[Steve L. <slo...@us...>]

Update of /cvsroot/linux-mips/linux/include/asm-generic
In directory usw-pr-cvs1:/tmp/cvs-serv30225/include/asm-generic

Added Files:
	mmu.h 
Log Message:
- consolidate all architectures to use type phys_addr_t for physical
  addresses. MIPS-only phys_t is gone, replaced with phys_addr_t.

- remap_page_range() will "fixup" physaddr's for platforms with 64-bit
  physaddr support enabled, just as __ioremap() does.

/*
 * Some cpu's (mips, ppc) have 32-bit virtual address space but
 * larger (36-bit) physical space. So the include/asm-[*]/mmu.h
 * have the option of redefining phys_addr_t. Also, fixup_bigphys_addr
 * can be redefined to "convert" a physaddr represented in 32 bits
 * to a phys_addr_t. How that's actually done is very platform-
 * specific, and is a hack no matter how it's done. It's a stop-gap
 * approach until the day the entire kernel deals with physical
 * addresses consistently.
