When any of the functions contained in NGbzero.S and GENbzero.S vector through *bzero_from_clear_user, we may end up taking a fault when executing one of the store alternate address space instructions. If this happens, the exception handler does not restore the %asi register. This commit fixes the issue by introducing a new exception handler that ensures the %asi register is restored when a fault is handled.

2017-05-09proc: try to remove use of FOLL_FORCE entirelyLinus Torvalds1-4/+1
We fixed the bugs in it, but it's still an ugly interface, so let's see if anybody actually depends on it. It's entirely possible that nothing actually requires the whole "punch through read-only mappings" semantics. For example, gdb definitely uses the /proc/<pid>/mem interface, but it looks like it mainly does it for regular reads of the target (that don't need FOLL_FORCE), and looking at the gdb source code seems to fall back on the traditional ptrace(PTRACE_POKEDATA) interface if it needs to. If this breaks something, I do have a (more complex) version that only enables FOLL_FORCE when somebody has PTRACE_ATTACH'ed to the target, like the comment here used to say ("Maybe we should limit FOLL_FORCE to actual ptrace users?").

2017-05-09net/mlx4_core: Reduce harmless SRIOV error message to debug levelJack Morgenstein2-4/+12
Under SRIOV resource management, extra counters are allocated to VFs from a free pool. If that pool is empty, the ALLOC_RES command for a counter resource fails -- and this generates a misleading error message in the message log. Under SRIOV, each VF is allocated (i.e., guaranteed) 2 counters -- one counter per port. For ETH ports, the RoCE driver requests an additional counter (above the guaranteed counters). If that request fails, the VF RoCE driver simply uses the default (i.e., guaranteed) counter for that port. Thus, failing to allocate an additional counter does not constitute a problem, and the error message on the PF when this occurs should be reduced to debug level. Finally, to identify the situation that the reason for the failure is that no resources are available to grant to the VF, we modified the error returned by mlx4_grant_resource to -EDQUOT (Quota exceeded), which more accurately describes the error.
