Spotted by itkes@fat.imed.msu.ru, the fn_hash_dump_bucket() main
loop does not increment 'i' properly, and thus routes will not
be listed, when the test 'i < s_i' passes.

The bug was added when the code was converted over to
hlist_for_each_entry() by your's truly.

It can only be set by root, but let's not tempt people to do
things that can't work.

setup_APIC_timer is only called in __init context and uses __initdata

wait_timer_tick refers to the __init functions wait_8254_wraparound
or wait_hpet_tick, hence must be __initdata.

scsi_dev_flags is referred to in
module_param_string(dev_flags, scsi_dev_flags, sizeof(scsi_dev_flags), 0);

cfq_init() calls __init cfq_slab_setup and hence must be __init itself

also made it static

parport_init_mode is referred to in int __devinit sio_via_probe().

I have just tested kernel version 2.6.11-rc5 and noticed it is not
possible to do an USB transfer by submitting an URB to an output
endpoint.  This breaks newest versions of libusb and thus SANE, gphoto2,
and a lot of software.

The bug was introduced in version 2.6.11-rc1 and is due to a wrong
comparison.

The attached patch makes keyctl() use the correct argument when invoking
the KEYCTL_JOIN_SESSION_KEYRING function.

I'm not sure how this evaded testing before, but I suspect the compiler was
kind and made both argument registers hold the same value.

This fixes a potentially bad (although very rarely triggered) bug in the
ppc64 hugepage code.

hpte_update() did not correctly calculate the address for hugepages, so
pte_clear() (which we use for hugepage ptes as well as normal ones)
would not correctly flush the hash page table entry.  Under the right
circumstances this could potentially lead to duplicate hash entries,
which is very bad.

davem's upcoming patch to pass the virtual address directly to set_pte()
and its ilk will obsolete this, but this is bad enough it should
probably be fixed in the meantime.

This is the best we've got: We cannot release and re-grab lock,
since checkentry() is called before ip_tables.c grabs ipt_mutex.  
We also cannot grab the hashtable spinlock, since htable_create will 
call vmalloc, and that can sleep.  And we cannot just re-search
the list of htable's in htable_create(), since then we would
create duplicate proc files.

IRQ races during change of mtu
- NAPI poll must be enabled prior to IRQ activation or the IRQ handler
  will not know what to do with an incoming packet;
- rtl8169_down() needs to try twice to sync with the IRQ handler when
  it is not issued under !netif_running() protection.

Some futex functions do get_user calls while holding mmap_sem for
reading.  If get_user() faults, and another thread happens to be in mmap
(or somewhere else holding waiting on down_write for the same
semaphore), then do_page_fault will deadlock.  Most architectures seem
to be exposed to this.

To avoid it, make sure the page is available.  If not, release the
semaphore, fault it in and retry.

I also found another exposure by inspection, moving some of the code
around avoids the possible deadlock there.

Advanced SATA drivers should not (and cannot) use the basic
PCI IDE hooks for checking the Status and Error registers, as these
registers are either in non-standard locations, or simply don't
exist.

In the error handling path, libata was unconditionally calling some
PCI IDE hardware bitbanging functions, which would cause an oops
in the AHCI driver and any other advanced libata driver.

Not that anybody cares about the sign, but the signed type does
the wrong thing for right shifts. Which we had.

Reworking the ppc32 mm helps me find interesting bugs in the existing bug,
well, brown paper bag for me, I made this one a while ago.

The routine flush_hash_one_pte() used by ptep_test_and_clear_young()
wasn't properly recaclulating the vaddr from the pte pointer &
page->index.  The result is that we probably never flushed things from
the hash, so that's at least the _second_ bug affecting
ptep_test_and_clear_young(), swap on ppc32 must have been really broken
:(

This fixes it.
