q35: change default NIC to e1000e
The e1000 NIC is getting old and is not a very good default for a
PCIe machine type. Change it to e1000e, which should be supported
by a good number of guests.
In particular, drivers for 82574 were added first to Linux 2.6.27 (2008)
and Windows 2008 R2. This does mean that Windows 2008 will not work
anymore with Q35 machine types and a default "-net nic -net xxx" network
configuration; it did work before because it does have an AHCI driver.
However, Windows 2008 has been declared out of main stream support
in 2015. It will get out of extended support in 2020. Windows 2008
R2 has the same end of support dates and, since the two are basically
Vista vs. Windows 7, R2 probably is more popular.

scsi-disk.c: consider bl->max_transfer in INQUIRY emulation
The calculation of the max_transfer atribute of BlockDriverState
makes considerations such as max_segments and transfer_length via
the BLKSECTGET ioctl (if available).
However, bl->max_transfer isn't considered when emulating the INQUIRY
'Block Limit' response to the scsi-hd devices. This leads to situations
where the declared max_sectors from the INQUIRY response is inconsistent
with the block limits, which isn't ideal. It can also be misleading to the
user that sets /sys/block/<dev>/queue/max_sectors_kb to a certain
value, then finds a different value in the guest OS for the same disk.
Following the same logic scsi_read_complete from scsi-generic.c does
when patching the response of the Block Limits VPD back to the guest,
change the max_io_sectors value of the emulated Block Limits VPD
response by considering the blk_get_max_transfer of the related
BlockDriverState. Use MIN_NOT_ZERO to be sure that the minimal
value is chosen.
Given that we're changing max_io_sectors, consider that min_io_sectors
and opt_io_sectors can't be greater than the new calculated value.

Sometimes, we want to refer to really long URLs, but checkpatch

may be nice at reducing long links, but it's hard to guarantee the
shortened link will live as long as the real target, and it is
also nice to see the original target without having to load the
shortened URL through a browser. So exempt a line containing
only a URL from the long-line syntax check.

TCP chardevs can be using QIO network listeners working in the

To solve this, we need to re-setup the net listeners in
tcp_chr_update_read_handler() with the newly cached gcontext.

chardev: introduce chr_machine_done hook
Introduce ChardevClass.chr_machine_done() hook so that chardevs can run

There was an existing mux user already that did similar thing but used a
raw machine done notifier. Generalize it into a framework, and let the
mux chardevs provide such a class-specific hook to achieve the same
thing. Then we can move the mux related code to the char-mux.c file.
Since at it, replace the mux_realized variable with the global
machine_init_done varible.
This notifier framework will be further leverged by other type of
chardevs soon.

Polish the version strings containing the package version
Since commit 67a1de0d195a there is no space anymore between the
version number and the parentheses when running configure with
--with-pkgversion=foo :
$ qemu-system-s390x --version
QEMU emulator version 2.11.50(foo)
But the space is included when building without that option
when building from a git checkout:
$ qemu-system-s390x --version
QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty)
The same confusion exists with the "query-version" QMP command.
Let's fix this by introducing a proper QEMU_FULL_VERSION definition
that includes the space and parentheses, while the QEMU_PKGVERSION
should just cleanly contain the package version string itself.
Note that this also changes the behavior of the "query-version" QMP
command (the space and parentheses are not included there anymore),
but that's supposed to be OK since the strings there are not meant
to be parsed by other tools.

hw/mips/jazz: Fix implicit creation of "-drive if=scsi" devices
The global hack for creating SCSI devices has recently been removed,
but this apparently broke SCSI devices on some boards that were not
ready for this change yet. For the pica61 machine you now get:
$ mips64-softmmu/qemu-system-mips64 -M pica61 -cdrom x.iso
qemu-system-mips64: -cdrom x.iso: machine type does not support
if=scsi,bus=0,unit=2
Fix it by calling scsi_bus_legacy_handle_cmdline() after creating the
corresponding SCSI controller.

rcu: make memory barriers more explicit
Prepare for introducing smp_mb_placeholder() and smp_mb_global().
The new smp_mb() in synchronize_rcu() is not strictly necessary, since
the first atomic_mb_set for rcu_gp_ctr provides the required ordering.
However, synchronize_rcu is not performance critical, and it *will* be
necessary to introduce a smp_mb_global before calling wait_for_readers().

membarrier: introduce qemu/sys_membarrier.h
This new header file provides heavy-weight "global" memory barriers that
enforce memory ordering on each running thread belonging to the current
process. For now, use a dummy implementation that issues memory barriers
on both sides (matching what QEMU has been doing so far).

Actually enable the global memory barriers if supported by the OS.
Because only recent versions of Linux include the support, they
are disabled by default. Note that it also has to be disabled
for QEMU to run under Wine.
Before this patch, rcutorture reports 85 ns/read for my machine,
after the patch it reports 12.5 ns/read. On the other hand updates
go from 50 *micro*seconds to 20 *milli*seconds.

cpu-exec: fix exception_index handling
Function cpu_handle_interrupt calls cc->cpu_exec_interrupt to process
pending hardware interrupts. Under the hood cpu_exec_interrupt uses
cpu->exception_index to pass information to the internal function which
is usually common for exception and interrupt processing.
But this value is not reset after return and may be processed again
by cpu_handle_exception. This does not happen due to overwriting
the exception_index at the end of cpu_handle_interrupt.
But this branch may also overwrite the valid exception_index in some cases.
Therefore this patch:
1. resets exception_index just after the call to cpu_exec_interrupt
2. prevents overwriting the meaningful value of exception_index

replay: push replay_mutex_lock up the call tree
Now instead of using the replay_lock to guard the output of the log we
now use it to protect the whole execution section. This replaces what
the BQL used to do when it was held during TCG execution.
We also introduce some rules for locking order - mainly that you
cannot take the replay_mutex while holding the BQL. This leads to some
slight sophistry during start-up and extending the
replay_mutex_destroy function to unlock the mutex without checking
for the BQL condition so it can be cleanly dropped in the non-replay
case.

tcg: fix cpu_io_recompile
cpu_io_recompile() function was broken by
the commit 9b990ee5a3cc6aa38f81266fb0c6ef37a36c45b9. Instead of regenerating
the block starting from PC of the original block, it just set the instruction
counter for TCG. In most cases this was unnoticed, but in icount mode
there was an exception for incorrect usage of CF_LAST_IO flag.
This patch recovers recompilation of the original block and also
configures translation for executing single IO instruction which
caused a recompilation.
