Franck Bui-Huu 99e3b942c6 [MIPS] page.h: remove __pa() usages.
__pa() was used by virt_to_page() and virt_addr_valid(). These
latter are used when kernel is initialised so __pa() is not
appropriate, we use virt_to_phys() instead.

Futhermore __pa() is going to take care of CKSEG0/XKPHYS
address mix for 64 bit kernels. This makes __pa() more complex
than virt_to_phys() and this extra work is not needed by
virt_to_page() and virt_addr_valid().

Eventually it consolidates virt_to_phys() prototype by making
its argument 'const'. this avoids some warnings that was due
to some virt_to_page() usages which pass const pointer.

Ralf Baechle d89e36d8df [MIPS] Fix iounmap argument to const volatile.
With the existing prototype the following code:

    const void __iomem *io = ioremap();
    x = readb(io);
    iounmap(io);

did result in a warning.

Matthew Wilcox e50190a834 [PATCH] Consolidate check_signature
There's nothing arch-specific about check_signature(), so move it to
<linux/io.h>.  Use a cross between the Alpha and i386 implementations as
the generic one.

Atsushi Nemoto a8433137ea [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.

Ralf Baechle 966f4406d9 [MIPS] Work around bad code generation for <asm/io.h>.
If a call to set_io_port_base() was being followed by usage of
mips_io_port_base in the same function gcc was possibly using the old
value due to some clever abuse of const.  Adding a barrier will keep
the optimization and result in correct code with latest gcc.

Linus Torvalds 1da177e4c3 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!
