mtd: nand: check status before reporting timeout
In commit b70af9bef49b ("mtd: nand: increase ready wait timeout and
report timeouts"), we increased the likelihood of scheduling during
nand_wait(). This makes us more likely to hit the time_before(...)
condition, since a lot of time may pass before we get scheduled again.
Now, the loop was already buggy, since we don't check if the NAND is
ready after exiting the loop; we simply print out a timeout warning. Fix
this by doing a final status check before printing a timeout message.
This isn't actually a critical bug, since the only effect is a false
warning print. But too many prints never hurt anyone, did they? :)
Side note: perhaps I'm not smart enough, but I'm not sure what the best
policy is for this kind of loop; do we busy loop (i.e., no
cond_resched()) to keep the lowest I/O latency (it's not great if the
resched is delaying Richard's system ~400ms)? Or do we allow
rescheduling, to play nice with the rest of the system (since some
operations can take quite a while)?

hv_netvsc: Move subchannel waiting to rndis_filter_device_remove()
During hot add, vmbus_device_register() is called from vmbus_onoffer(), on
the same workqueue as the subchannel offer message work-queue, so
subchannel offer won't be processed until the vmbus_device_register()/...
/netvsc_probe() is done.
Also, vmbus_device_register() is called with channel_mutex locked, which
prevents subchannel processing too. So the "waiting for sub-channel
processing" will not success in hot add case. But, in usual module loading,
the netvsc_probe() is called from different code path, and doesn't fail.
This patch resolves the deadlock during NIC hot-add, and speeds up NIC
loading time.

vmxnet3: avoid calling pskb_may_pull with interrupts disabled
vmxnet3 has a function vmxnet3_parse_and_copy_hdr which, among other operations,
uses pskb_may_pull to linearize the header portion of an skb. That operation
eventually uses local_bh_disable/enable to ensure that it doesn't race with the
drivers bottom half handler. Unfortunately, vmxnet3 preforms this
parse_and_copy operation with a spinlock held and interrupts disabled. This
causes us to run afoul of the WARN_ON_ONCE(irqs_disabled()) warning in
local_bh_enable, resulting in this:
Fix it by splitting vmxnet3_parse_and_copy_hdr into two functions:
vmxnet3_parse_hdr, which sets up the internal/on stack ctx datastructure, and
pulls the skb (both of which can be done without holding the spinlock with irqs
disabled
and
vmxnet3_copy_header, which just copies the skb to the tx ring under the lock
safely.
