sh: Fix mmap2 for handling differing PAGE_SIZEs.

2009-04-20T22:34:53+00:00

mmap2 uses a fixed page shift of 12, regardless of the PAGE_SIZE setting.
Fix up the mmap2 code to add some sanity checks on the mapping, and to
update pgoff accordingly.

Error handling bits based on 4280e3126f641898f0ed1a931645373d3489e2a6

sh: Move arch_get_unmapped_area() in to arch/sh/mm/mmap.c.

2008-12-22T09:42:49+00:00

Now that arch/sh/mm/mmap.c exists, move arch_get_unmapped_area() there.
Follows the ARM change.

sh: Trivial trace_mark() instrumentation for core events.

2008-09-21T04:56:39+00:00

This implements a few trace points across events that are deemed
interesting. This implements a number of trace points:

	- The page fault handler / TLB miss
	- IPC calls
	- Kernel thread creation

The original LTTng patch had the slow-path instrumented, which
fails to account for the vast majority of events. In general
placing this in the fast-path is not a huge performance hit, as
we don't take page faults for kernel addresses.

The other bits of interest are some of the other trap handlers, as
well as the syscall entry/exit (which is better off being handled
through the tracehook API). Most of the other trap handlers are corner
cases where alternate means of notification exist, so there is little
value in placing extra trace points in these locations.

Based on top of the points provided both by the LTTng instrumentation
patch as well as the patch shipping in the ST-Linux tree, albeit in a
stripped down form.

remove include/asm-*/ipc.h

2007-10-17T15:42:55+00:00

All asm/ipc.h files do only #include .

This patch therefore removes all include/asm-*/ipc.h files and moves the
contents of include/asm-generic/ipc.h to include/linux/ipc.h.

Remove includes of  where it is not used/needed.

sh: Fixup kernel_execve() for syscall cleanups.

2006-12-11T23:42:08+00:00

SH-2 and SH-2A need to use a different syscall base for the trapa
vector than the other parts, so fixup the logic in the kernel_execve()
case.
