Previously -EAGAIN is simply ignored for !s->io_q.plugged case,
and sometimes it is easy to cause -EIO to VM, such as NVME device.
This patch handles -EAGAIN by io queue for !s->io_q.plugged case,
and it will be retried in following aio completion cb.

The 1st patch fixes batch submission.
The 2nd one fixes -EAGAIN for non-batch case.
The 3rd one is a cleanup.
This patchset is splitted from previous patchset(dataplane: optimization
and multi virtqueue support), as suggested by Stefan.
V6:
- don't pass ioq_submit() return value to ioq_
In the submit path, we can't complete request directly,
otherwise "Co-routine re-entered recursively" may be caused,
so this patch fixes the issue with below ideas:
- for -EAGAIN or partial completion, retry the submision
in following completion cb which is run in BH context
No one uses the 'node' field any more, so remove it
from 'struct qemu_laiocb', and this can save 16byte
for the struct on 64bit arch.

No one uses the 'node' field any more, so remove it
from 'struct qemu_laiocb', and this can save 16byte
for the struct on 64bit arch.

Previously -EAGAIN is simply ignored for !s->io_q.plugged case,
and sometimes it is easy to cause -EIO to VM, such as NVME device.
This patch handles -EAGAIN by io queue for !s->io_q.plugged case,
and it will be retried in following aio completion cb.

The 1st patch fixes batch submission.
The 2nd one fixes -EAGAIN for non-batch case.
The 3rd one is a cleanup.
This patchset is splitted from previous patchset(dataplane: optimization
and multi virtqueue support), as suggested by Stefan.
V5:
- in case of submission failure, return -EIO for n
In the submit path, we can't complete request directly,
otherwise "Co-routine re-entered recursively" may be caused,
so this patch fixes the issue with below ideas:
- for -EAGAIN or partial completion, retry the submision
in following completion cb which is run in BH context

This reverts commit 000c4dfff4d7686e2fba3066a477a1290ed60622.
The main reason for reverting this commit before the 2.2 release is that
it adds a QAPI interface that we don't want to keep: The 'nocow' flag
doesn't generally make sense for block nodes, but only for the raw-posix
driver. It should th

This patch fixes an obscure failure of the QNX kernel on QEMU x86 SMP.
In QNX, all hardware interrupts come via the PIC, and are delivered by
the cpu 0 LAPIC in ExtINT mode, while IPIs are delivered by the LAPIC
in fixed mode.
This bug happens as follows:
- cpu 0 masks a particular PIC interrupt
-
This fixes another failure with ExtINT, demonstrated by QNX. The failure
mode is as follows:
- IPI sent to cpu 0 (bit set in APIC irr)
- IPI accepted by cpu 0 (bit cleared in irr, set in isr)
- IPI sent to cpu 0 (bit set in both irr and isr)
- PIC interrupt sent to cpu 0
The PIC interrupt causes
After the next patch, if a masked PIC interrupts causes CPU_INTERRUPT_POLL
to be set, the CPU will spuriously get out of halted state. While this
is technically valid, we should avoid that.
Make CPU_INTERRUPT_POLL run apic_update_irq in the right thread and then
look at CPU_INTERRUPT_HARD. If CP

The test enables intel_iommu on q35, looks for and reads the DMAR table as well
as its only DRHC structure (for now), checking the header and checksums.
