All Haswell CPUs and some Broadwell CPUs were updated by Intel to have
the HLE and RTM features disabled. This will prevent
"-cpu Haswell,enforce" and "-cpu Broadwell,enforce" from running out of
the box on those CPUs.

Disable those features by default on Broadwell and Haswell CPU models,
starting on pc-*-2.3. Users who want to use those features can enable
them explicitly on the command-line.

Right now you only get to apic_init_reset if you have an APIC
(do_cpu_init is reached only if CPU_INTERRUPT_INIT is set and
that only happens in hw/intc/apic.c).  However, this is wrong
because for example a port 92 or keyboard controller reset is
really an INIT, and that can happen also with no APIC.  So
keep the check and fix the error that Coverity reported.

kvm_stat uses syscall() to call perf_event_open(). If this function
call fails, the returned value is -1, which doesn't tell the details
of such failure (i.e. ENOSYS or EINVAL). This patch retrieves errno
and prints it when syscall() fails. The error message will look like
"Exception: perf_event_open failed, errno = 38".

Old users of VMSTATE_TIMER* are mechanically changed to VMSTATE_TIMER_PTR
variants.
Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

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: NPaolo 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
is remaining enabled.

When ever USB keyboard is used, e.g. '-usbdevice keyboard' pressing
caps lock key send 0x32 hid code, which is treated as backslash.
Instead it should be 0x39 code. This affects sending uppercase keys,
as they typed whith caps lock active.

While on x86 this can be workarounded by using ps/2 protocol. On
Power it is crusial as we don't have anything else than USB.

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.
