CVS commit: src/sys/uvm
Module Name: src
Committed By: uebayasi

ERESTART is already negative. Give up negating error values to not override
the original values. Pointed out by rmind@, thanks.
In the lower fault case, if (*pgo_get)() can return ERESTART and we should
re-fault for that remains a question. The original code just returned the
error, so keep that behaviour for now. In case (*pgo_get)() really returns
ERESTART, pass EIO to tell the uvm_fault caller that (*pgo_get)() failed.
(As far as I grep callers don't check if the return value is ERESTART or not.
So assuming (*pgo_get)() never returns ERESTART should be a safe bet.)
