Thanks to Dru <andru@treshna.com>, who provided an easy way to reproduce
the problem.

What we have in lib/rwsem.c:__rwsem_do_wake():
	int woken, loop;
	^^^
and several lines below:
	loop = woken;
	woken *= RWSEM_ACTIVE_BIAS-RWSEM_WAITING_BIAS;
	woken -= RWSEM_ACTIVE_BIAS;

However, rw_semaphore->count is 64-bit on Alpha, so
RWSEM_WAITING_BIAS has been defined as -0x0000000100000000L.
Obviously, this blows up in the write contention case.

Fix new ISDN CAPI's internal ncci list semaphore if
CONFIG_ISDN_CAPI_MIDDLEWARE is disabled.

Thanks to Florian Schirmer.

This patch updates support for the Motorola PrPMC750 platform.  Most of the
size in this patch comes from merging prpmc750_pci.c and prpmc750_setup.c into
just prpmc750.c.

This patch adds openpic_hookup_cascade(offset, name, handler) which allows for
an arbitrary interrupt controller to be hooked up as a cascade to the openpic.
 This also allows for platforms to just not have a cascaded controller.

When I changed some '#if FOO' tests to '#ifdef FOO' I forgot to make sure

On pSeries LPARs we might end up with NUMA nodes that only have memory and
no CPUs.  Only the CPU configuration code actually set a node online, so
memory-only nodes wouldn't show up in sysfs.  Below patch adds the
set_online call to the memory loop too.

We cannot always rely on ->biotail remaining untouched. Currently we
leak all the pinned user pages when doing cdda ripping at least, so I
see no way around keeping the bio pointer seperate and passing it back
in for unmap. Alternatively, we could invent a struct blk_map_data and
put it on the stack for passing to both map and unmap.

An unintentional sign extention caused non-ascii characters to be
stored incorrectly, leading to inaccessible files.  Changing a
declaration to unsigned char fixes the problem.

The external module support recently introduced caused a number of problems:
- To build an external module the Module.symvers file was needed
- To create the Module.symvers file a module was required
- If Module.symvers was missing kbuild boiled out with an error
- If vmlinux was missing also the stage 2 of module build failed (make -k)
- It was not documented what was needed to actually bauild a module

The following patch addresses this by adding the following functionality:
- Always generate the Module.symvers file
- Ignore a missing Module.symvers file
- Add a new target modules_prepare, it prepares the kernel for building
  external modules, and is also usefull with O=
- And it adds some more comments to Makefile.modpost, so others may follow
  it with some luck
- .modpost.cmd is no longer generated

This should close all reports on issues with respect to building external
modules with current kernel - which has been identified as kernel problems.

Looking again at the SELinux ptrace check, I believe that there is an
unrelated race due to the fact that the parent link is only updated after
releasing the task lock in ptrace_attach (and this is necessary as task lock
doesn't nest with write lock of tasklist_lock).

The patch below changes SELinux to save the tracing process' SID upon a
successful selinux_ptrace hook call and then use that SID in the ptrace check
in apply_creds in order to avoid such races.  This allows us to preserve the
fine-grained process-to-process ptrace check upon exec (vs.  the global
CAP_SYS_PTRACE privilege => PT_PTRACE_CAP flag used by the capability module)
while still avoiding races.

I pinged the author the first time on the 2nd of april but still didn't get

ignored it.  Here's the patch again:
