[Qemu-devel] [PULL 1/4] qemu-ga: build it even if !system

[Michael Tokarev]

Move qemu-ga build check out of if softmmu.. into its own section.
We want to build qemu-ga for _guest_ even if system build isn't
done.  It is controlled separately using --enable-guest-agent.
Additionally, give error message if guest agent is requested but
not supported.

[Qemu-devel] [PULL 2/4] block/iscsi.c: Fix printf format error.

[Michael Tokarev]

From: "Richard W.M. Jones" <rjones@redhat.com>

The error on armv7hl was:

block/iscsi.c: In function ‘is_request_lun_aligned’:
block/iscsi.c:251:26: error: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘int64_t’ [-Werror=format=]
                          iscsilun->block_size, sector_num, nb_sectors);
                          ^

This also splits the long line to comply with qemu coding guidelines.

[Michael Tokarev]

From: Fam Zheng <famz@redhat.com>

The comment was truncated. Add the missing parts, especially explain why
we need zero_dry_run.

You are mixing 2- and 4-char indentation here...
