Pan Nengyuan f3a508eb4e armv7m_systick: delay timer_new to avoid memleaks 
There is a memory leak when we call 'device_list_properties' with typename = armv7m_systick. It's easy to reproduce as follow:

  virsh qemu-monitor-command vm1 --pretty '{"execute": "device-list-properties", "arguments": {"typename": "armv7m_systick"}}'

This patch delay timer_new to fix this memleaks.

Rene Stange eb87ff05ea bcm2835_dma: Fix the ylen loop in TD mode 
In TD (two dimensions) DMA mode ylen has to be increased by one after
reading it from the TXFR_LEN register, because a value of zero has to
result in one run through of the ylen loop. This has been tested on a
real Raspberry Pi 3 Model B+. In the previous implementation the ylen
loop was not passed at all for a value of zero.

Richard Henderson d63d0ec59d target/arm: Raise only one interrupt in arm_cpu_exec_interrupt 
The fall through organization of this function meant that we
would raise an interrupt, then might overwrite that with another.
Since interrupt prioritization is IMPLEMENTATION DEFINED, we
can recognize these in any order we choose.

Unify the code to raise the interrupt in a block at the end.

Richard Henderson e2cce18f5c target/arm: Add VHE system register redirection and aliasing 
Several of the EL1/0 registers are redirected to the EL2 version when in
EL2 and HCR_EL2.E2H is set.  Many of these registers have side effects.
Link together the two ARMCPRegInfo structures after they have been
properly instantiated.  Install common dispatch routines to all of the
relevant registers.

The same set of registers that are redirected also have additional
EL12/EL02 aliases created to access the original register that was
redirected.

Omit the generic timer registers from redirection here, because we'll
need multiple kinds of redirection from both EL0 and EL2.

Liang Yan 0999a4ba87 target/arm/monitor: query-cpu-model-expansion crashed qemu when using machine type none 
Commit e19afd5667 mentioned that target-arm only supports queryable
cpu models 'max', 'host', and the current type when KVM is in use.
The logic works well until using machine type none.

For machine type none, cpu_type will be null if cpu option is not
set by command line, strlen(cpu_type) will terminate process.
So We add a check above it.

This won't affect i386 and s390x since they do not use current_cpu.

Daniel P. Berrangé 416b71906e docs: stop documenting the e1000 NIC model as the default 
The default NIC model for QEMU varies per machine type, and is liable to
change across machine type versions. Documenting e1000 NIC as the
default for PC/i386 is thus misleading to users at best. In particular
the PC q35 machine type switched to use e1000e, but only in machine
type versions after 2.11.

Rather than try to explain which NIC model is used for each machine
type version, remove mention of e1000 as the default, and steer users
towards always specifying their desired model.

Jafar Abdi 834e8bf17c authz: fix usage of bool in listfile.c 
Clean up wrong usage of FALSE and TRUE in places that use "bool" from stdbool.h.

FALSE and TRUE (with capital letters) are the constants defined by glib for
being used with the "gboolean" type of glib. But some parts of the code also use
TRUE and FALSE for variables that are declared as "bool" (the type from <stdbool.h>).

Yu-Chen Lin c64e1e7538 io/channel-websock: treat 'binary' and no sub-protocol as the same 
noVNC doesn't use 'binary' protocol by default after
commit c912230309806aacbae4295faf7ad6406da97617.

It will cause qemu return 400 when handshaking.

To overcome this problem and remain compatibility of
older noVNC client.

We treat 'binary' and no sub-protocol as the same
so that we can support different version of noVNC
client.

Tested on noVNC before c912230 and after c912230.
