Philippe Mathieu-Daudé 83bb745154 hw/remote: Add missing include
Currently "qemu/error-report.h" is implicitly included, however
if headers in include/ get refactored, we get:

  hw/remote/proxy-memory-listener.c: In function ‘proxy_memory_listener_commit’:
  hw/remote/proxy-memory-listener.c:183:9: error: implicit declaration of function ‘error_report’; did you mean ‘error_report_err’? [-Werror=implicit-function-declaration]
    183 |         error_report("Number of fds is more than %d", REMOTE_MAX_FDS);
        |         ^~~~~~~~~~~~
        |         error_report_err

Add the missing "qemu/error-report.h" header to avoid that.

Thomas Huth 546f292d63 tests/qtest/ide-test: Remove bad retry_isa test
The retry_isa test is not doing what it was intended for: The
test_retry_flush() function ignores the machine parameter completely
and thus this test does not get run with the "isapc" machine.
Moreover, in the course of time, the test_retry_flush() has been
changed to depend on PCI-related functions, so this also cannot
be fixed by simply using the machine parameter now. The correct
fix would be to switch the whole test to libqos, but until someone
has time to do this, let's simply drop the retry_isa test for now.

Fabiano Rosas 65e0446c86 target/ppc: Move common SPR functions out of cpu_init
Let's leave cpu_init with just generic CPU initialization and
QOM-related functions.

The rest of the SPR registration functions will be moved in the
following patches along with the code that uses them. These are only
the commonly used ones.

Fabiano Rosas b58fd0c39b target/ppc: cpu_init: Move check_pow and QOM macros to a header
These will need to be accessed from other files once we move the CPUs
code to separate files.

The check_pow_hid0 and check_pow_hid0_74xx are too specific to be
moved to a header so I'll deal with them later when splitting this
code between the multiple CPU families.

Fabiano Rosas 917ea4381a target/ppc: cpu_init: Expose some SPR registration helpers
The following patches will move CPU-specific code into separate files,
so expose the most used SPR registration functions:

register_sdr1_sprs         | 22 callers
register_low_BATs          | 20 callers
register_non_embedded_sprs | 19 callers
register_high_BATs         | 10 callers
register_thrm_sprs         | 8 callers
register_usprgh_sprs       | 6 callers
register_6xx_7xx_soft_tlb  | only 3 callers, but it helps to
                             keep the soft TLB code consistent.

Fabiano Rosas 99e964ef95 target/ppc: Rename spr_tcg.h to spr_common.h
Initial intent for the spr_tcg header was to expose the spr_read|write
callbacks that are only used by TCG code. However, although these
routines are TCG-specific, the KVM code needs access to env->sprs
which creation is currently coupled to the callback registration.

We are probably not going to decouple SPR creation and TCG callback
registration any time soon, so let's rename the header to spr_common
to accomodate the register_*_sprs functions that will be moved out of
cpu_init.c in the following patches.
