[MIPS] Rename CONFIG_BUILD_ELF64 into KBUILD_64BIT_SYM32

2007-10-11T22:45:59+00:00

This patch renames it for 3 reasons:

    - "CONFIG" pattern is used by Kconfig. Now this macro is
      no more defined by Kconfig but by Kbuild itself make this
      clear by translating "CONFIG" into "KBUILD".

    - "ELF32" word is improper because it is irrelevant to ELF
      format and it makes confusion with CONFIG_BOOT_ELF32. So
      translate it with SYM32.

    - Add "64BIT" part to make clear that this macro implies a
      64 bits kernel.

[MIPS] Automatically set CONFIG_BUILD_ELF64

2007-10-11T22:45:59+00:00

We do not rely on user anymore to setup this config correctly.
Instead we make our choice depending on the load address.

If we want to force Kbuild to use ELF64 format whatever
the load address we can still do:

        $ make BUILD_ELF32=no

[MIPS] Fix CONFIG_BUILD_ELF64 kernels with symbols in CKSEG0.

2007-09-27T22:19:16+00:00

The __pa() for those did assume that all symbols have XKPHYS values and
the math fails for any other address range.

[MIPS] Fix PHYS_OFFSET for 64-bits kernels with 32-bits symbols

2007-07-10T16:32:57+00:00

The current implementation of __pa() for 64-bits kernels with 32-bits
symbols is broken. In this configuration, we need 2 values for
PAGE_OFFSET, one in XKPHYS and the other in CKSEG0 space.

When the value in CKSEG0 space is used, it doesn't take into account
of PHYS_OFFSET. Even worse we can't redefine this value.

The patch restores CPHYSADDR() but in __pa()'s implementation because
it removes the need of 2 PAGE_OFFSET.

OTOH, CPHYSADDR() is quite bad when dealing with mapped kernels. So
this patch assumes there's no need to deal with such kernel in 64-bits
world.

[MIPS] FLATMEM: introduce PHYS_OFFSET.

2007-02-06T16:53:13+00:00

The old code was assuming that min_low_pfn was always 0. This
means that platforms having a big hole at their memory start
paid the price of wasting some memory for the allocation of
unused entries in mem_map[].

This patch prevents this waste.

It introduces PHYS_OFFSET define which is the start of the
physical memory and uses it wherever needed. Specially when
converting physical/virtual addresses into virtual/physical
ones.

Currently all platforms defines PHYS_OFFSET to 0.

[PATCH] MIPS: Fix COW D-cache aliasing on fork

2006-12-13T17:27:08+00:00

Provide a custom copy_user_highpage() to deal with aliasing issues on
MIPS.  It uses kmap_coherent() to map an user page for kernel with same
color.  Rewrite copy_to_user_page() and copy_from_user_page() with the
new interfaces to avoid extra cache flushing.

The main part of this patch was originally written by Ralf Baechle;
Atushi Nemoto did the the debugging.
