Philippe Mathieu-Daudé 858be92357 hw/timer/hpet: Include "exec/address-spaces.h"
hw/timer/hpet.c calls address_space_stl_le() declared in
"exec/address-spaces.h". Include it.

This fixes (when modifying unrelated headers):

Define the new macro VMSTATE_INSTANCE_ID_ANY for callers who wants to
auto-generate the vmstate instance ID.  Previously it was hard coded
as -1 instead of this macro.  It helps to change this default value in

Cédric Le Goater 2ec11f2320 aspeed: Change the "scu" property definition
The Aspeed Watchdog and Timer models have a link pointing to the SCU
controller model of the machine.

Change the "scu" property definition so that it explicitly sets the
pointer. The property isn't optional : not being able to set the link
is a bug and QEMU should rather abort than exit in this case.

Philippe Mathieu-Daudé 8ce60a7518 hw/i386: Remove obsolete LoadStateHandler::load_state_old handlers
These devices implemented their load_state_old() handler 10 years
ago, previous to QEMU v0.12.
Since commit cc425b5ddf removed the pc-0.10 and pc-0.11 machines,
we can drop this code.

Note: the mips_r4k machine started to use the i8254 device just
after QEMU v0.5.0, but the MIPS machine types are not versioned,
so there is no migration compatibility issue removing this handler.

Peter Maydell 5e3478925d hw/timer/slavio_timer: Remove useless check for NULL t->timer
In the slavio timer device, the ptimer TimerContext::timer is
always created by slavio_timer_init(), so there's no need to
check it for NULL; remove the single unneeded NULL check.

This will be useful to avoid compiler/Coverity errors when
a subsequent change adds a use of t->timer before the location
we currently do the NULL check.

Guenter Roeck 1a391e20c3 hw/timer/exynos4210_mct: Initialize ptimer before starting it
When booting a recent Linux kernel, the qemu message "Timer with delta
zero, disabling" is seen, apparently because a ptimer is started before
being initialized.  Fix the problem by initializing the offending ptimer
before starting it.

The bug is effectively harmless in the old QEMUBH setup
because the sequence of events is:
 * the delta zero means the timer expires immediately
 * ptimer_reload() arranges for exynos4210_gfrc_event() to be called
 * ptimer_reload() notices the zero delta and disables the timer
 * later, the QEMUBH runs, and exynos4210_gfrc_event() correctly
   configures the timer and restarts it

In the new transaction based API the bug is still harmless,
but differences of when the callback function runs mean the
message is not printed any more:
 * ptimer_run() does nothing as it's inside a transaction block
 * ptimer_transaction_commit() sees it has work to do and
   calls ptimer_reload()
 * the zero delta means the timer expires immediately
 * ptimer_reload() calls exynos4210_gfrc_event() directly
 * exynos4210_gfrc_event() configures the timer
 * the delta is no longer zero so ptimer_reload() doesn't complain
   (the zero-delta test is after the trigger-callback in
   the ptimer_reload() function)

Regardless, the behaviour here was not intentional, and we should
just program the ptimer correctly to start with.
