Trond Myklebust b079fa7baa RPC: Do not block on skb allocation
If we get something like the following,
 [  125.300636]  [<c04086e1>] schedule_timeout+0x54/0xa5
 [  125.305931]  [<c040866e>] io_schedule_timeout+0x29/0x33

 [  125.317058]  [<c014136b>] throttle_vm_writeout+0x69/0x7d
 [  125.322720]  [<c014714d>] shrink_zone+0xe0/0xfa
 [  125.327560]  [<c01471d4>] shrink_caches+0x6d/0x6f
 [  125.332581]  [<c01472a6>] try_to_free_pages+0xd0/0x1b5

 [  125.348281]  [<c03d4666>] inet_sendmsg+0x48/0x53
 [  125.353212]  [<c0388716>] sock_sendmsg+0xb8/0xd3
 [  125.358147]  [<c0388773>] kernel_sendmsg+0x42/0x4f
 [  125.363259]  [<c038bc00>] sock_no_sendpage+0x5e/0x77
 [  125.368556]  [<c03ee7af>] xs_tcp_send_request+0x2af/0x375
 then the socket is blocked until memory is reclaimed, and no
 progress can ever be made.

 Try to access the emergency pools by using GFP_ATOMIC.
