to deal with it and fixes numerous other issues. Along with this change,
adjust getcontext() and makecontext() to fill out additional important
fields in the ucontext that sigreturn() inspects.
* Fixes two stack corruption bugs. First, getcontext() was calling
get_mcontext() and get_mcontext() was setting up the setcontext return
state to return 1 ... from get_mcontext(), NOT from getcontext(). If
normal operations or signals mess with the stack, the double return
will not work. Oops.
Secondly, getcontext scribbled over the red-zone in a way that is not
permitted.
* setcontext() was restoring the context as saved by makecontext() or
getcontext(), but setcontext() can also be called with the ucontext
from the signal handler which requires a full restore. setcontext()
was not restoring FPU or scratch registers or rflags.

igb: Optimize the aggregated TX/RX MSI-X handler a bit
By checking whether there are any TX descs to collect or not, before
holding the TX ring serializer.
This requires that igb_txeof() is only called in interrupt handler,
thus we remove the igb_txeof() from igb_start(), which does nothing
most of the time. Removal of igb_txeof() from igb_start() also allows
us to simplify the TX ring OACTIVE detection, so several unused water
marks are also removed.

igb: Partly rework MSI-X support to bypass one serializer
For aggregated TX/RX MSI-X handler, there is no need to use
an independent serializer; using RX ring's serializer just
works (well, this driver's MSI-X support was added when we
still lacked of experience about how to serialize aggregated
TX/RX MSI-X handler).
Enable aggregated TX/RX MSI-X handling by default to avoid
extra TX interrupt (though its pretty low for TCP streams).
