firewire: ohci: work around VIA and NEC PHY packet reception bug

VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell).  Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.

(Also tested:  TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)

Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround.  Though to me it seems harmless enough
to enable for all controllers.

The log_ar_at_event() debug log will continue to show the original
status from the DMA unit.

a newly allocated anon_vma's lock - on a box with CONFIG_TREE_PREEMPT_RCU=y

nfsd4: fix downgrade/lock logic

If we already had a RW open for a file, and get a readonly open, we were
piggybacking on the existing RW open.  That's inconsistent with the
downgrade logic which blows away the RW open assuming you'll still have

Also, make sure there is a readonly or writeonly open available for

SUS defined 'ready for writing' of select() as following.

|  function with O_NONBLOCK clear would not block, whether or not the function

That said, EPIPE situation is clearly one of 'ready for writing'.

We don't have read-side issue because tcp_poll() already has read side

A better ground is to use size of ehash table, this also makes code
