6c0bb9e576 HFI1: Range-check proc->fd_priv_table[] 
sockioctl01.c in LTP calls ioctl(1025, ...) and causes kernel page-fault without
the range-check.

6279f69f5c compiler.h: take in recent linux updates for newer gcc support 
Had to remove from original compiler-gcc:
 - things that deal with types, e.g. READ_ONCE macro and friends;
 - #define barrier(). This one would be better there at some point.

f5ced648ef hfi1/user_exp_rcv: rework main loop 
New loop now takes into account pages not physically contiguous.
Also some minor improvements, e.g. make the spin_lock used more locally,
reuse a group we had if we had one, etc.

e64d89cd48 hfi: bases for user_exp_rcv 
This implements a skeleton setup function and call it on ioctl

Many missing points:
 - missing pci mapping to make setup work
 - no clear (passed to linux, so will likely bug out)
 - missing locks/safe-guards

7366da4390 Fix other warnings 
Most were harmless, but the change to ACCESS_ONCE from volatile
cast is probably useful.
Expanding macro, we basically went from:
    m = (volatile struct sdma_vl_map *)dd->sdma_map;
to
    m = *(volatile struct sdma_vl_map **)&(dd->sdma_map);
i.e. the explicit lookup is at a different level.
