9516034d05 Some qemu updates for IPMI and I2C
Move some ADC file to where they belong and move some sensors to a
 sensor directory, since with new BMCs coming in lots of different
 sensors should be coming in.  Keep from cluttering things up.
 
 Add support for I2C PMBus devices.
 
 Replace the confusing and error-prone i2c_send_recv and i2c_transfer with
 specific send and receive functions.  Several errors have already been
 made with these, avoid any new errors.
 
 Fix the watchdog_expired field in the IPMI watchdog, it's not a bool,
 it's a u8.  After a vmstate transfer, the new value could be wrong.

fc32b91a88 ppc patch queue 2021-07-09
Here's a (probably) final pull request before the qemu-6.1 soft
 freeze.  Includes:
   * Implementation of the new H_RPT_INVALIDATE hypercall
   * Virtual Open Firmware for pSeries and pegasos2 machine types.
     This is an experimental minimal Open Firmware implementation which
     works by delegating nearly everything to qemu itself via a special
     hypercall.
   * A number of cleanups to the ppc soft MMU code
   * Fix to handling of two-level radix mode translations for the
     powernv machine type
   * Update the H_GET_CPU_CHARACTERISTICS call with newly defined bits.
     This will allow more flexible handling of possible future CPU
     Spectre-like flaws
   * Correctly treat mtmsrd as an illegal instruction on BookE cpus
   * Firmware update for the ppce500 machine type

In use_goto_tb, the check for singlestep_enabled is in the

check for singlestep_enabled is in the preceding do_debug test.

Which leaves only FLAG_MASK_PER: fold that test alone into

ca92d7f89b target/cris: Use translator_use_goto_tb
The test for singlestepping is done in translator_use_goto_tb,
so we may elide it from cris_tr_tb_stop.

a50d52bc3b target/avr: Use translator_use_goto_tb
Single stepping is not the only reason not to use goto_tb.
If goto_tb is disallowed, and single-stepping is not enabled,
then use tcg_gen_lookup_and_goto_tb to indirectly chain.

0285162bdf target/arm: Use translator_use_goto_tb for aarch64
We have not needed to end a TB for I/O since ba3e792669
("icount: clean up cpu_can_io at the entry to the block"),
and gdbstub singlestep is handled by the generic function.

Drop the unused 'n' argument to use_goto_tb.

73fce314db target/arm: Use DISAS_TOO_MANY for ISB and SB
Using gen_goto_tb directly misses the single-step check.
Let the branch or debug exception be emitted by arm_tr_tb_stop.
