[PATCH 0/2] QEMU DCD emulation support fix

[nifan.cxl@gmail.com]

From: Fan Ni <fan.ni@samsung.com>

In Ira's latest DCD kernel patchset[1], the More flag support has been
added. While testing it with mainstream Qemu, I identified two issues
with Qemu.

1. For a DC extent add request with more than one extents, the More flag
for the last one is not correctly set.
2. The function cxl_event_insert should only return true for the last event
record in a sequence grouped via More flag so interrupt will only be
triggered once for the sequence not every record.

After the fix of the first issue, the More flag works as expected.
While the test can pass without the second patch which fixes the second issue,
but I think we make sense to notify the OS only when all the records
are put in the event log.
