In the SMMU_STRTAB_BASE register, the stream table base address only
occupies bits [51:6]. Other bits, such as RA (bit [62]), must be masked
out to obtain the base address.
The branch for 2-level stream tables correctly applies this mask by way
of SMMU_BASE_ADDR_MASK, but the one for linear stream tables does not.
Apply the missing mask in that case as well so that the correct stream
base address is used by guests which configure a linear stream table.
Linux guests are unaffected by this change because they choose a 2-level
stream table layout for the QEMU SMMUv3, based on the size of its stream
ID space.

The ASPEED AST2600 clocks the generic timer at the rate of HPLL. On
recent firmwares this is at 1125MHz, which is considerably quicker than
the assumed 62.5MHz of the current generic timer implementation. The
delta between the value as read from CNTFRQ and the true rate of the
underlying QEMUTimer leads to sticky behaviour in AST2600 guests.
Add a feature-gated property exposing CNTFRQ for ARM CPUs providing the
generic timer. This allows platforms to configure CNTFRQ (and the
associated QEMUTimer) to the appropriate frequency prior to starting the
guest.
As the platform can now determine the rate of CNTFRQ we're exposed to
limitations of QEMUTimer that didn't previously materialise: In the
course of emulation we need to arbitrarily and accurately convert
between guest ticks and time, but we're constrained by QEMUTimer's use
of an integer scaling factor. The effect is QEMUTimer cannot exactly
capture the period of frequencies that do not cleanly divide
NANOSECONDS_PER_SECOND for scaling ticks to time. As such, provide an
equally inaccurate scaling factor for scaling time to ticks so at least
a self-consistent inverse relationship holds.

Prepare for SoCs such as the ASPEED AST2600 whose firmware configures
CNTFRQ to values significantly larger than the static 62.5MHz value
currently derived from GTIMER_SCALE. As the OS potentially derives its
timer periods from the CNTFRQ value the lack of support for running
QEMUTimers at the appropriate rate leads to sticky behaviour in the
guest.
Substitute the GTIMER_SCALE constant with use of a helper to derive the
period from gt_cntfrq_hz stored in struct ARMCPU. Initially set
gt_cntfrq_hz to the frequency associated with GTIMER_SCALE so current
behaviour is maintained.

All callers of nbd_iter_channel_error() pass the address of a
local_err variable, and only call this function if an error has
already occurred, using this function to propagate that error.
This is already implied by its name (local_err instead of the classic
errp), but it is worth additionally stressing this by adding an
assertion to make it part of the function contract.
The local_err parameter is not here to return information about
nbd_iter_channel_error failure. Instead it's assumed to be filled when

commit 3eb99edb48 "loader-fit: Wean off error_printf()".
No caller actually passes such values, or uses *errp on success.
Fix anyway: splice in a local Error *err, and error_propagate().

legacy_acpi_cpu_plug_cb() dereferences @errp when
acpi_set_cpu_present_bit() fails. That's wrong; see the big comment
in error.h. Introduced in commit cc43364de7 "acpi/cpu-hotplug:
introduce helper function to keep bit setting in one place".
No caller actually passes null, and acpi_set_cpu_present_bit() can't
actually fail.
Fix anyway: drop acpi_set_cpu_present_bit()'s @errp parameter.

When os_mem_prealloc() fails, file_ram_alloc() calls qemu_ram_munmap()
and returns null. Except it doesn't when its @errp argument is null,
because it checks for failure with (errp && *errp). Introduced in
commit 056b68af77 "fix qemu exit on memory hotplug when allocation
fails at prealloc time".
No caller actually passes null.
Fix anyway: splice in a local Error *err, and error_propagate().

Declaring a local Error *err without initializer looks suspicious.
Fuse the declaration with the initialization to avoid that.

qcrypto_tls_creds_load_cert() passes uninitialized GError *gerr by
reference to g_file_get_contents(). When g_file_get_contents() fails,
it'll try to set a GError. Unless @gerr is null by dumb luck, this
logs a ERROR_OVERWRITTEN_WARNING warning message and leaves @gerr
unchanged. qcrypto_tls_creds_load_cert() then dereferences the
uninitialized @gerr.
Fix by initializing @gerr properly.

-msg parameter "timestamp" defaults to "off" if you don't specify msg,
and to "on" if you do. Messed up right in commit 5e2ac51917 "add
timestamp to error_report()". Mostly harmless, because "timestamp" is
the only parameter, so "if you do" is "-msg ''", which nobody does.
Change the default to "off" no matter what.
While there, rename enable_timestamp_msg to error_with_timestamp, and
polish documentation.
