Richard Henderson b0748975b8 tcg: Remove TCG_CALL_PLUGIN
Since we no longer emit plugin helpers during the initial code
translation phase, we don't need to specially mark plugin helpers.

Richard Henderson 8a2927f290 plugins: Use emit_before_op for PLUGIN_GEN_FROM_MEM
Introduce a new plugin_mem_cb op to hold the address temp
and meminfo computed by tcg-op-ldst.c.  Because this now
has its own opcode, we no longer need PLUGIN_GEN_FROM_MEM.

By having the qemu_plugin_cb_flags be recorded in the TCGHelperInfo,
we no longer need to distinguish PLUGIN_CB_REGULAR from
PLUGIN_CB_REGULAR_R, so place all TB callbacks in the same queue.

Alexandra DiupinaandPeter Maydell 4b00855f0e hw/dmax/xlnx_dpdma: fix handling of address_extension descriptor fields
The DMA descriptor structures for this device have
a set of "address extension" fields which extend the 32
bit source addresses with an extra 16 bits to give a
48 bit address:
 https://docs.amd.com/r/en-US/ug1085-zynq-ultrascale-trm/ADDR_EXT-Field

However, we misimplemented this address extension in several ways:
 * we only extracted 12 bits of the extension fields, not 16
 * we didn't shift the extension field up far enough
 * we accidentally did the shift as 32-bit arithmetic, which
   meant that we would have an overflow instead of setting
   bits [47:32] of the resulting 64-bit address

Add a type cast and use extract64() instead of extract32()
to avoid integer overflow on addition. Fix bit fields
extraction according to documentation.

Peter Maydell f037f5b4b9 target/arm: Default to 1GHz cntfrq for 'max' and new CPUs
In previous versions of the Arm architecture, the frequency of the
generic timers as reported in CNTFRQ_EL0 could be any IMPDEF value,
and for QEMU we picked 62.5MHz, giving a timer tick period of 16ns.
In Armv8.6, the architecture standardized this frequency to 1GHz.

Because there is no ID register feature field that indicates whether
a CPU is v8.6 or that it ought to have this counter frequency, we
implement this by changing our default CNTFRQ value for all CPUs,
with exceptions for backwards compatibility:

 * CPU types which we already implement will retain the old
   default value. None of these are v8.6 CPUs, so this is
   architecturally OK.
 * CPUs used in versioned machine types with a version of 9.0
   or earlier will retain the old default value.

The upshot is that the only CPU type that changes is 'max'; but any
new type we add in future (whether v8.6 or not) will also get the new
1GHz default.

It remains the case that the machine model can override the default
value via the 'cntfrq' QOM property (regardless of the CPU type).
