Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[MIPS] Make I/O helpers more customizable 1. Move ioswab*() and __mem_ioswab*() to mangle-port.h. This gets rid of CONFIG_SGI_IP22 from include/asm-mips/io.h. 2. Pass a virtual address to *ioswab*(). Then we can provide mach-specific *ioswab*() and can do every evil thing based on its argument. It could be useful on machines which have regions with different endian conversion scheme. 3. Call __swizzle_addr*() _after_ adding mips_io_port_base. This unifies the meaning of the argument of __swizzle_addr*() (always virtual address). Then mach-specific __swizzle_addr*() can do every evil thing based on the argument. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
