Patch from Russ Dill

The oprofile init code was broken in commit c6b9da. The new logic will
always return -ENODEV. This fixes oprofile_arch_init to return 0 on
success, and return the return value of spec->init() if applicable.

Patch from Richard Purdie

ip_fast_csum() accesses memory via a pointer (iph) within an
asm function. To prevent memory corruption when the function is
inlined, it needs "memory" on the clobber list.

This fixes ip checksum errors reported by a Zaurus user.

AACI reports TX FIFO full after the first write to it if the AC97 is not

FIFO size. The patch also adds a warning if the TX FIFO size is not

This patch fixes the AMD POGO errata on the hotplug controller where the
platform will lock up or reboot if PERR/SERR generation is enabled and a
slot is sent an enable command.  This fix disables PERR/SERR generation
before a slot is sent the enable command by first saving related
registers, turning off SERR/PERR generation, enabling the slot, then
restoring the registers.

Removing and then adding a PCI slot to a running partition results in
a kernel panic. The current code attempts to add iospace for an entire
root bus, which is inappropriate, and silently fails.  When a pci device
tries to use the iospace, a page fault is taken, as the iospace had not
been mapped, and of course the page fault cannot be resolved.

This only occurs for PCI adapters using pio, which may be why it hadn't
been seen earlier (this seems to have been broken for a while).
This patch has survived testing of dozens of slot add and removes.

It was copy&pasted from tcp_v6_send_synack() which has

Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch fix dst reference counting in tcp_v6_send_synack

Analysis:
Currently tcp_v6_send_synack is never called with a dst entry
so dst always comes in as NULL.

ip6_dst_lookup calls ip6_route_output which calls dst_hold
before it returns the dst entry.   Neither xfrm_lookup
nor tcp_make_synack consume the dst entry so we still have
a dst_entry with a bumped refrence count at the end of
this function.

Therefore we need to call dst_release just before we return
just like tcp_v4_send_synack does.
