sh: linker script tidying.

2007-10-30T08:38:03+00:00

Some cleanups to the SH linker script. This reorders some of the
data sections for more optimal placement, general tabification,
and plugging in omitted generic definitions.

sh: Kill off legacy embedded ramdisk section.

2007-10-30T08:25:29+00:00

When the SH kernel used to support embedding a ramdisk in the
pre-initramfs days it was placed in a special section and made to
look like a regular initrd. Since that was removed ages ago, kill
off the remaining cruft that was missed.

sh: Discard .exit.text/.exit.data at runtime.

2007-10-09T06:23:02+00:00

These were previously discarded at link time, though as with MIPS
we keep them around until runtime to satisfy .rodata references.

sh: Fix up some section alignments in linker script.

2007-10-09T06:20:53+00:00

With the PERCPU() macro introduction .data.cacheline_aligned was
inhereting PAGE_SIZE alignment, fix that up for L1_CACHE_BYTES
again. Likewise, the initramfs section wants PAGE_SIZE alignment.

sh: Define _ebss for uClinux MTD map driver.

2007-09-24T09:11:27+00:00

The uClinux MTD device uses _ebss, add the symbol and corresponding
export.

sh: Move entry point code to .text.head.

2007-07-20T08:40:03+00:00

Follow Al Viro's m68k change from l-k:

	i.e. tell modpost that entry point code (that has to be outside
	of .init.text for external reasons) is OK to refer to .init.*

Shuts up some section mismatch warnings from modpost.

define new percpu interface for shared data

2007-07-19T17:04:44+00:00

per cpu data section contains two types of data.  One set which is
exclusively accessed by the local cpu and the other set which is per cpu,
but also shared by remote cpus.  In the current kernel, these two sets are
not clearely separated out.  This can potentially cause the same data
cacheline shared between the two sets of data, which will result in
unnecessary bouncing of the cacheline between cpus.

One way to fix the problem is to cacheline align the remotely accessed per
cpu data, both at the beginning and at the end.  Because of the padding at
both ends, this will likely cause some memory wastage and also the
interface to achieve this is not clean.

This patch:

Moves the remotely accessed per cpu data (which is currently marked
as ____cacheline_aligned_in_smp) into a different section, where all the data
elements are cacheline aligned. And as such, this differentiates the local
only data and remotely accessed data cleanly.

sh: Align .machvec.init section on a 4-byte boundary.

2007-06-08T02:43:41+00:00

.machvec.init can be misaligned with the recent machvec changes,
forcibly align it on the boundary that it expects, as before.
