sh: Kill off the remaining ST40 cruft.

2007-11-07T02:13:55+00:00

The ST40 stuff in-tree hasn't built for some time, and hasn't been
updated for over 3 years. ST maintains their own out-of-tree changes
and rebases occasionally, and that's ultimately where all of the ST40
users go anyways.

In order for the ST40 code to be brought up to date most of the stuff
removed in this changeset would have to be rewritten anyways, so there's
very little benefit in keeping the remnants around either.

sh: Export __{s,u}divsi3_i4i on all CPUs.

2007-11-07T02:13:55+00:00

Currently these are only being exported for CONFIG_CPU_SH4. This
invariably breaks when building for an SH-3 that includes multiple
targets in multilib.

sh: Fix up kgdb-on-NMI branch target.

2007-11-07T02:13:55+00:00

This was all reworked some time ago, the old debug_enter was ripped
out with everything going through a debug trap jump table instead.
Kill off the debug_enter target and reference kgdb_handle_exception
directly.

sh: Kill off duplicate includes.

2007-11-07T02:13:54+00:00

Caught by the surprisingly not-entirely-useless 'includecheck'.

sh: Terminate .eh_frame in VDSO with a 4-byte 0.

2007-11-02T03:29:37+00:00

It's assumed that .eh_frame is terminated with 4-byte 0 in shared
libraries and executable.  It seems to be the case for VDSOs too.
Without this terminator, I saw failures when unwinding from VDSO,
though I don't know how other architectures handle this issue.
For the normal libs, crtendS.o gives this terminator.  We can use
such terminating objects.  Or we can add a 4-byte 0 with modifying
the linker script like as the patch below.

sh: Decouple 4k and soft/hardirq stacks.

2007-11-02T03:16:51+00:00

While using separate IRQ stacks can cut down on stack consumption,
many users can also use 4k stacks directly without the additional
need of separate stacks for soft and hardirqs.

With this split, we support the same rationale for 4KSTACKS as
m68knommu, with the IRQSTACKS abstraction as per ppc64.

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.
