drivers/net: ks8842 Fix crash on received packet when in PIO mode.
This patch fixes a driver crash during packet reception due to not enough
bytes allocated in the skb. Since the loop reads out 4 bytes at a time, we
need to allow for up to 3 bytes of slack space.
The current code takes an unaligned pointer and does htonl() on it to
make it big-endian, then does a memcpy(). The problem is that the
compiler decides that since the pointer is to a __be32, it is legal
to optimize the copy into a processor word store. However, on an
architecture that does not handled unaligned writes in kernel space,
this produces an unaligned exception fault.
The solution is to track the pointer as a "char *" (which removes a bunch
of unpleasant casts in any case), and then just use put_unaligned_be32()
to write the value to memory.

Implement using the new event_idx feature.
Note: it might seem advantageous to let the drivers
ask for a callback after a specific capacity has
been reached. However, as a single head can
free many entries in the descriptor table,
we don't really have a clue about capacity
until get_buf is called. The API is the simplest
to implement at the moment, we'll see what kind of
hints drivers can pass when there's more than one
user of the feature.
Support for the new event idx feature:
1. When enabling interrupts, publish the current avail index
value to the host to get interrupts on the next update.
2. Use the new avail_event feature to reduce the number
of exits from the guest.
Simple test with the simulator:
[virtio]# time ./virtio_test
spurious wakeus: 0x7
real 0m0.169s
user 0m0.140s
sys 0m0.019s
[virtio]# time ./virtio_test --no-event-idx
spurious wakeus: 0x11
With the new used_event and avail_event and features, both
host and guest need similar logic to check whether events are
enabled, so it helps to put the common code in the header.
Note that Xen has similar logic for notification hold-off
in include/xen/interface/io/ring.h with req_event and req_prod
corresponding to event_idx + 1 and new_idx respectively.
+1 comes from the fact that req_event and req_prod in Xen start at 1,

Without this feature, we might free a page (and have another
user touch it) while the hypervisor is unprepared for it.

reverse the order; we're under no obligation to do _anything_.
As of now, qemu-kvm defines the bit, but doesn't set it.
This patch makes the "tell host first" logic the only case. This
should make everybody happy, and reduce the amount of untested or

pnfs-obj: pg_test check for max_io_size
Implement pg_test vector to test for max IO sizes. We calculate
a max_io_size member only once, and cache it in lseg so to not
do so on every page insert.

NFSv4.1: define nfs_generic_pg_test
By default, unless pnfs is used coalesce pages until pg_bsize
(rsize or wsize) is reached.
pnfs layout drivers define their own pg_test methods that use
pnfs_generic_pg_test and need to define their own I/O size
limits (e.g. based on the file stripe size).
