In some cases, a timer was set to NULL so that we could check if it is
initialized. Use the timer_list field instead, and add a timer_deinit
function that NULLs it.
It then makes sense that timer_del be a no-op (instead of a crasher) on
such a de-initialized timer. It avoids the need to poke at the timerlist
field to check if the timers are initialized.

Right now, the AVX512 registers are split in many different fields:
xmm_regs for the low 128 bits of the first 16 registers, ymmh_regs
for the next 128 bits of the same first 16 registers, zmmh_regs
for the next 256 bits of the same first 16 registers, and finally
hi16_zmm_regs for the full 512 bits of the second 16 bit registers.
This makes it simple to move data in and out of the xsave region,
but would be a nightmare for a hypothetical TCG implementation and
leads to a proliferation of [XYZ]MM_[BWLSQD] macros. Instead,
this patch marshals data manually from the xsave region to a single
32x512-bit array, simplifying the macro jungle and clarifying which
bits are in which vmstate subsection.
The migration format is unaffected.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
After the next patch, each vmstate field will extract parts of a larger
(32x512-bit) array, so we cannot check the vmstate field against the
type of the array.
While changing this, change the macros to accept the index of the first
element (which will not be 0 for Hi16_ZMM_REGS) instead of the number
of elements (which is always CPU_NB_REGS).

Due to a typo, instead of disabling KVM_FEATURE_PV_EOI (bit
6) these machine types are disabling bits 1 and 2, which are
KVM_FEATURE_NOP_IO_DELAY and KVM_FEATURE_MMU_OP. Not a big deal
because they aren't very important and KVM_FEATURE_MMU_OP is
disabled anyway. The worst part is actually that KVM_FEATURE_PV_EOI

Instead it should be 0x39 code. This affects sending uppercase keys,

While on x86 this can be workarounded by using ps/2 protocol. On

Add new query vnc qmp command, for the lack of better ideas just name it
"query-vnc-servers". Changes over query-vnc:
* It returns a list of vnc servers, so multiple vnc server instances
are covered.
* Each vnc server returns a list of server sockets. Followup patch
will use that to also report websockets. In case we add support for
multiple server sockets server sockets (to better support ipv4+ipv6
dualstack) we can add them to the list too.

Also track the number of connections in "connecting" and "shared" state
(in addition to the "exclusive" state). Apply a configurable limit to
these connections.
The logic to apply the limit to connections in "shared" state is pretty
simple: When the limit is reached no new connections are allowed.
The logic to apply the limit to connections in "connecting" state (this
is the state you are in *before* successful authentication) is
slightly different: A new connect kicks out the oldest client which is
still in "connecting" state. This avoids a easy DoS by unauthenticated
users by simply opening connections until the limit is reached.

SoundBlaster 16 emulation is very broken and consumes a lot of CPU, but a

The processing of the interrupt register is wrong due to two missing
"not"s. This causes the interrupt flag to remain set even after the
Acknowledge ports have been read (0x0e and 0x0f).
The line was introduced by commit 85571bc (audio merge (malc), 2004-11-07),
but the code might have been broken before because I did not look closely

Not all targets define a full set of suffix strings for the
NB_MMU_MODES that they have. In this situation, don't define any
helper functions for that mode, rather than defining helper functions
with no suffix at all. The MMU mode is still functional; it is merely
not directly accessible via cpu_ld*_MODE from target helper functions.

helpers -- some targets only define one MMU mode.

Use inline functions rather than macros for cpu_ld/st accessors
for the *-user configurations, as we already do for softmmu.
This has a two advantages:
* we can actually typecheck our arguments
* we don't need to leak the _raw macros everywhere
Since the _kernel functions were only used by target-i386/seg_helper.c,
put the definitions for them in that file too. (It already has the
similar template include code to define them for the softmmu case,
