If we move the local_irq_enable() to the end of the function then
add_partial() in early_kmem_cache_node_alloc() will be called
with interrupts disabled like during regular operations.

This makes lockdep happy.

The clock_was_set() call in seconds_overflow() which happens only when
leap seconds are inserted / deleted is wrong in two aspects:

1. it results in a call to on_each_cpu() with interrupts disabled
2. it is potential deadlock source vs. call_lock in smp_call_function()

The only possible side effect of the removal might be, that an absolute
CLOCK_REALTIME timer fires 1 second too late, in the rare case of leap
second deletion and an absolute CLOCK_REALTIME timer which expires in
the affected time frame. It will never fire too early.

This was probably observed by the reporter of a June 30th -> July 1st

A similar problem was observed by Dave Jones, who provided a screen shot
with a lockdep back trace, which allowed to analyse the problem.

If a page can't be allocated for the frag list of a skb, the code to
unmap the partially allocated list is off by one.  For exaple, if
'frags' equals one, i == 0, and the alloc_page() fails, then the old
loop would have unmapped mapping[1] which is uninitialized.  The same
would happen if the call to ib_dma_map_page() failed.

Changed PATA handler for PATA-ports used by sata_sis.
This patch was originally submitted by Jeff Garzik.

Added PCI-ID 1180 for SiS966 Controller in pata_sis.
The 1180 mode is fully compatible to other SiS PATA-controller.

The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible
to SiS5513/5518. sata_sis.c is forwarding this ID to pata_sis.
1183 is not working if simply added to pata_sis.
This handling fixes issues with SiS968.

Recently the PLL input clock of pata_pdc2027x is sometimes detected
higer than expected (e.g. 20.027 MHz compared to 16.714 MHz).
It seems sometimes the mdelay() function is not as precise as it
used to be. Per Alan's advice, HT or power management might affect
the precision of mdelay().

This patch calls gettimeofday() to mesure the time elapsed and
calculate the PLL input clock accordingly.
