Its possible that we can write to the hvc_console tty as soon it is
registered. Recently this started happening due to (what looks like) a
change to the hotplug code.
Unfortunately at this stage we have not started the khvcd kernel thread and
oops. The solution is to start the kernel thread before registering the
tty.

[ALSA] Remove superfluous PCI ID definitions
broke the RME32 and RME96 drivers, since the PCI IDs they use seem to have
changed names. Here's a patch to fix this -- compile tested only, since I
have no idea what the hardware even is.
Fix the build of the RME32 and RME96 drivers by having them use the
PCI_DEVICE_ID_RME_xxx names defined in <linux/pci_ids.h> instead of the
PCI_DEVICE_ID_xxx names that they used to define themselves.
Also fix the typo in the id PCI_DEVICE_IDRME__DIGI96_8_PAD_OR_PST so the
name is PCI_DEVICE_ID_RME_DIGI96_8_PAD_OR_PST.

Noted by David Miller:
"The bug is that free_fd_array() takes a "num" argument, but when
calling it from __free_fdtable() we're instead passing in the size in
bytes (ie. "num * sizeof(struct file *)")."
Yes it is a bug. I think I messed it up while merging newer
changes with an older version where I was using size in bytes
to optimize.

With the new changes that we made in the initialization of the slab
allocator, we first setup the cache from which array caches are allocated,
and then the cache, from which kmem_list3's are allocated.
Now if the array cache comes from a cache in which objsize > 32, (in this
instance size-64) then, first size-64 cache will be allocated and then the
size-128 (if this is the cache from which kmem_list3's are going to be
allocated).
So with these new changes, we are not guaranteed that we will be
initializing the malloc_sizes array in a serialized order. Thus there is
a bug in __find_general_cachep, as we are checking whether the first
cache_sizes ptr is NULL.
This is replaced by checking whether the array-cache cache is initialized.
Attached is a patch which does that. Boots fine on a x86-64, with
DEBUG_SPIN, DEBUG_SLAB, and preempt.

In some cases, especially on modern laptops with a lot of PCI and
cardbus bridges, we're unable to assign correct secondary/subordinate
bus numbers to all cardbus bridges due to BIOS limitations unless
we are using "pci=assign-busses" boot option.
So some cardbus controllers may not have attached subordinate pci_bus
structure, and yenta driver must cope with it - just ignore such cardbus
bridges.

Pavel Emelianov and Kirill Korotaev observe that fs and arch users of
security_vm_enough_memory tend to forget to vm_unacct_memory when a
failure occurs further down (typically in setup_arg_pages variants).
These are all users of insert_vm_struct, and that reservation will only
be unaccounted on exit if the vma is marked VM_ACCOUNT: which in some
cases it is (hidden inside VM_STACK_FLAGS) and in some cases it isn't.
So x86_64 32-bit and ppc64 vDSO ELFs have been leaking memory into
Committed_AS each time they're run. But don't add VM_ACCOUNT to them,
it's inappropriate to reserve against the very unlikely case that gdb
be used to COW a vDSO page - we ought to do something about that in
do_wp_page, but there are yet other inconsistencies to be resolved.
The safe and economical way to fix this is to let insert_vm_struct do
the security_vm_enough_memory check when it finds VM_ACCOUNT is set.
And the MIPS irix_brk has been calling security_vm_enough_memory before
calling do_brk which repeats it, doubly accounting and so also leaking.
Remove that, and all the fs and arch calls to security_vm_enough_memory:
give it a less misleading name later on.

It turns out that the BUG_ON() in fs/exec.c: de_thread() is unreliable
and can trigger due to the test itself being racy.
de_thread() does
while (atomic_read(&sig->count) > count) {
}
.....
.....
BUG_ON(!thread_group_empty(current));
but release_task does
write_lock_irq(&tasklist_lock)
__exit_signal
(this is where atomic_dec(&sig->count) is run)
__exit_sighand
__unhash_process
takes write lock on tasklist_lock
remove itself out of PIDTYPE_TGID list
write_unlock_irq(&tasklist_lock)
so there's a clear (although small) window between the
atomic_dec(&sig->count) and the actual PIDTYPE_TGID unhashing of the
thread.
And actually there is no need for all threads to have exited at this
point, so we simply kill the BUG_ON.
Big thanks to Marc Lehmann who provided the test-case.

Certain (SGI?) ia64 boxes object to having their PCI BARs
restored unless absolutely necessary. This patch restricts calling
pci_restore_bars from pci_set_power_state unless the current state
is PCI_UNKNOWN, the actual (i.e. physical) state of the device is
PCI_D3hot, and the device indicates that it will lose its configuration
when transitioning to PCI_D0.

Jeff,
sorry if I have flooded your inbox, I had some problems with the
mail server here yesterday, but it seems to be fixed ...
Ok patch 3-4 have no dependencies on patch 2 since only qeth driver is
affected.Thus I have made a new patch 2 for ctc driver.
Thank you .

Do not count non-error frames dropped by the hardware as
part of rx_dropped. Instead, count those frames dropped as
rx_missed_errors. Also, do not count other error frames as part of
rx_dropped. Finally, do not count oversized frames in rx_dropped
(since they are counted as part of rx_length_errors).
