[PPC] 8xx: swap bug-fix

2008-03-07T22:56:54+00:00

This makes swap routines operate correctly on the ppc_8xx based machines.

Recent kernel's size makes swap feature very important on low-memory platfor
those are actually non-operable without it.

remove support for un-needed _extratext section

2008-02-06T18:41:01+00:00

When passing a zero address to kallsyms_lookup(), the kernel thought it was
a valid kernel address, even if it is not.  This is because is_ksym_addr()
called is_kernel_extratext() and checked against labels that don't exist on
many archs (which default as zero).  Since PPC was the only kernel which
defines _extra_text, (in 2005), and no longer needs it, this patch removes
_extra_text support.

all archs: consolidate init and exit sections in vmlinux.lds.h

2008-01-28T22:21:17+00:00

This patch consolidate all definitions of .init.text, .init.data
and .exit.text, .exit.data section definitions in
the generic vmlinux.lds.h.

This is a preparational patch - alone it does not buy
us much good.

Because the data field was never filled and a binary sysctl handler was
never written this sysctl has never been usable through the sys_sysctl
interface.  So just remove the binary sysctl number.  Making the kernel
sanity checks happy.

[POWERPC] Move RapidIO support code from arch/ppc

2008-01-24T01:35:15+00:00

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