[POWERPC] ppc: Don't run prom_init_check for arch/ppc builds

arch/ppc doesn't have prom_init.o (anymore).

[RAPIDIO] Add OF-tree support to RapidIO controller driver

2008-04-29T09:40:28+00:00

This initializes the RapidIO controller driver using addresses and
interrupt numbers obtained from the firmware device tree, rather than
using hardcoded constants.

[POWERPC] Discourage people from fiddling with kernel data from prom_init

2008-04-24T10:58:03+00:00

As BenH said the other day, it is an "accident" that prom_init.o is
linked with the rest of the kernel.  The truth is a little more
subtle, prom_init isn't truly bootloader, it does access kernel data
in a few places.

What we can do is discourage people from adding new code that accesses
data outside of prom_init.  And hence this patch; from the script:

 # This script checks prom_init.o to see what external symbols it
 # is using, if it finds symbols not in the whitelist it returns
 # an error. The point of this is to discourage people from
 # intentionally or accidentally adding new code to prom_init.c
 # which has side effects on other parts of the kernel.

Generic semaphore implementation

2008-04-17T14:42:34+00:00

Semaphores are no longer performance-critical, so a generic C
implementation is better for maintainability, debuggability and
extensibility.  Thanks to Peter Zijlstra for fixing the lockdep
warning.  Thanks to Harvey Harrison for pointing out that the
unlikely() was unnecessary.

[POWERPC] Switch to generic compat_binfmt_elf code

2008-02-07T09:40:18+00:00

This switches the CONFIG_PPC64 support for 32-bit ELF to use the
generic fs/compat_binfmt_elf.c implementation instead of our own
binfmt_elf32.c.  Since so much is the same between 32/64, there is
only one macro we have to define to make the generic support work out
of the box.

[POWERPC] Add user_regset_view definitions

2008-02-07T09:40:16+00:00

This provides the task_user_regset_view entry point and support for
all the native-mode (64 on CONFIG_PPC64, 32 on CONFIG_PPC32) thread
register state.  This will enable generic machine-independent code to
access user-mode threads' registers for debugging and dumping.

Do just enough to move the RapidIO support code for 85xx over from arch/ppc
into arch/powerpc and make it still build.
