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.
--- NEW FILE: mmu.h ---

/*
* 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.
