powerpc: Remove arch/ppc and include/asm-ppc

2008-06-10T11:40:22+00:00

All the maintained platforms are now in arch/powerpc, so the old
arch/ppc stuff can now go away.

[POWERPC] Export empty_zero_page and copy_page in arch/ppc

2008-05-31T07:08:28+00:00

Currently ext4 and fuse fail to link if modular:
ERROR: "copy_page" [fs/fuse/fuse.ko] undefined!
ERROR: "empty_zero_page" [fs/ext4/ext4dev.ko] undefined!
make[3]: *** [__modpost] Error 1
make[2]: *** [modules] Error 2
make[1]: *** [sub-make] Error 2

While arch ppc exists it may as well compile, so this exports those
symbols (which are already exported in arch/powerpc).

[POWERPC] Define and use TLF_RESTORE_SIGMASK

2008-05-14T12:31:33+00:00

Replace TIF_RESTORE_SIGMASK with TLF_RESTORE_SIGMASK and define
our own set_restore_sigmask() function.  This saves the costly
SMP-safe set_bit operation, which we do not need for the sigmask
flag since TIF_SIGPENDING always has to be set too.

[POWERPC] ppc: More compile fixes

2008-05-12T12:57:51+00:00

This fixes a few more miscellaneous compile problems with ARCH=ppc.

1. Don't compile devres.c on ARCH=ppc, it doesn't have ioremap_flags.
2. Include  in setup.c for the __DO_IRQ_CANON definition.
3. Include  in residual.c for the
   definition of create_proc_read_entry.
4. Fix xchg_ptr to be a static inline to eliminate a compiler warning.

[POWERPC] ppc: Include in kernel/ppc_ksyms.c

2008-05-12T10:27:50+00:00

It needs it:

	arch/ppc/kernel/ppc_ksyms.c:152: error: '__flush_icache_range'
	undeclared here (not in a function)

and a few more like that.

Basic braille screen reader support

2008-04-30T15:29:52+00:00

This adds a minimalistic braille screen reader support.  This is meant to
be used by blind people e.g.  on boot failures or when / cannot be mounted
etc and thus the userland screen readers can not work.

iomap: fix 64 bits resources on 32 bits

2008-04-29T15:06:02+00:00

Almost all implementations of pci_iomap() in the kernel, including the generic
lib/iomap.c one, copies the content of a struct resource into unsigned long's
which will break on 32 bits platforms with 64 bits resources.

This fixes all definitions of pci_iomap() to use resource_size_t.  I also
"fixed" the 64bits arch for consistency.

[POWERPC] Add strncmp to arch/ppc

2008-04-24T10:57:34+00:00

Commit 0119536cd314ef95553604208c25bc35581f7f0a added an assembly
version of strncmp to PowerPC.  However, it changed a common header
file between arch/ppc and arch/powerpc without adding strncmp to
arch/ppc.  This fixes that omission so that arch/ppc links again.
