[SPARC64]: Kill bogus check from bootmem_init().
There is an ancient and totally incorrect sanity check being
done on the ramdisk location. The check assumes that the
kernel is always loaded to physical address zero, which is
wrong. It was trying to validate the ramdisk value by saying that
if it fell within the kernel image address range it must be wrong.
Anyways, kill this because it actually creates problems. The
'ramdisk_image' should always be adjusted down by KERNBASE.
SILO can easily put the ramdisk in a location which causes
this test to trigger, breaking things.

If the cpu is preempted or put to sleep by the hypervisor in
__call_usermodehelper between the creation of the wait_for_helper

of wait_for_helper including the complete call and the continuation
after the wait_for_completion in call_usermodehelper_keys can have
happened before __call_usermodehelper checks sub_info->wait for the

sub_info->wait could be zero and complete is called a second time

Convert idr's internal locking to _irqsave variant
Currently, the code in lib/idr.c uses a bare spin_lock(&idp->lock) to do
internal locking. This is a nasty trap for code that might call idr
functions from different contexts; for example, it seems perfectly
reasonable to call idr_get_new() from process context and idr_remove() from
interrupt context -- but with the current locking this would lead to a
potential deadlock.
The simplest fix for this is to just convert the idr locking to use
spin_lock_irqsave().
In particular, this fixes a very complicated locking issue detected by

As a general note, this code of unqueue_me seems a bit fishy. The retry logic
of unqueue_me only works if we can guarantee, that the original value of
q->lock_ptr is always a spinlock (Otherwise we overwrite kernel memory). We
know that q->lock_ptr can change. I dont know what happens with the original

In the event that our entire receive buffer is full with a series of
chunks that represent a single gap-ack, and then we accept a chunk

we renege chunks from the end of the buffer, which effectively does
nothing but move our gap to the end of our received tsn stream. This
does little but move our missing tsns down stream a little, and, if the
sender is sending sufficiently large retransmit frames, the result is a
perpetual slowdown which can never be recovered from, since the only
chunk that can be accepted to allow progress in the tsn stream necessitates
that a new gap be created to make room for it. This leads to a constant
need for retransmits, and subsequent receiver stalls. The fix I've come up

1394: fix for recently added firewire patch that breaks things on ppc
Recently a patch was added for preliminary suspend/resume handling on
!PPC_PMAC. However, this broke both suspend and firewire on powerpc
because it saves the pci state after the device has already been disabled.
This moves the save state to before the pmac specific code.

sctp_make_abort_user() now takes the msg_len along with the msg
so that we don't have to recalculate the bytes in iovec.
It also uses memcpy_fromiovec() so that we don't go beyond the
length allocated.
It is good to have this fix even if verify_iovec() is fixed to
return error on overflow.
