Patch for boot-time USB hangs in 4.9-PRERELEASE
...be helpful to get more feedback to
determine if this is the right fix to be committed.
The problem was that interrupts were getting unmasked too early in
the boot process, causing an interrupt storm that usually occurred
while USB devices were being probed. The bug is in fork1(), which
is used by kthread_create() to create kernel threads; the code there
assumed that all interrupts would be unmasked when called, so it
didn't bother saving and restoring the interrupt mask. This assumption
is reasonable for normal fork() calls, but not for the creation of
kernel threads early in the boot process.

of a specific virtqueue into its address space. This is help to reudce
the syscall or vmexit overhead.
