c551fb0b53 module: add Error arguments to module_load and module_load_qom
improve error handling during module load, by changing:

bool module_load(const char *prefix, const char *lib_name);
void module_load_qom(const char *type);

to:

int module_load(const char *prefix, const char *name, Error **errp);
int module_load_qom(const char *type, Error **errp);

where the return value is:

 -1 on module load error, and errp is set with the error
  0 on module or one of its dependencies are not installed
  1 on module load success
  2 on module load success (module already loaded or built-in)

module_load_qom_one has been introduced in:

commit 28457744c3 ("module: qom module support"), which built on top of
module_load_one, but discarded the bool return value. Restore it.

Adapt all callers to emit errors, or ignore them, or fail hard,
as appropriate in each context.

Replace the previous emission of errors via fprintf in _some_ error
conditions with Error and error_report, so as to emit to the appropriate
target.

A memory leak is also fixed as part of the module_load changes.

audio: when attempting to load an audio module, report module load errors.
Note that still for some callers, a single issue may generate multiple
error reports, and this could be improved further.
Regarding the audio code itself, audio_add() seems to ignore errors,
and this should probably be improved.

block: when attempting to load a block module, report module load errors.
For the code paths that already use the Error API, take advantage of those
to report module load errors into the Error parameter.
For the other code paths, we currently emit the error, but this could be
improved further by adding Error parameters to all possible code paths.

console: when attempting to load a display module, report module load errors.

qdev: when creating a new qdev Device object (DeviceState), report load errors.
      If a module cannot be loaded to create that device, now abort execution
      (if no CONFIG_MODULE) or exit (if CONFIG_MODULE).

qom/object.c: when initializing a QOM object, or looking up class_by_name,
              report module load errors.

qtest: when processing the "module_load" qtest command, report errors
       in the load of the module.

b5d3dac170 meson: avoid unused arguments of main() in compiler tests
meson.build has one test where "main" is declared unnecessarily
with argc and argv arguments, but does not use them.  Because
the test needs -Werror too, HAVE_BROKEN_SIZE_MAX is defined
incorrectly.

Fix the test and, for consistency, remove argc and argv whenever
they are not needed.

8a0afbb2a4 Fix broken configure with -Wunused-parameter
The configure script fails because it tries to compile small C programs
with a main function which is declared with arguments argc and argv
although those arguments are unused.

Running `configure -extra-cflags=-Wunused-parameter` triggers the problem.
configure for a native build does abort but shows the error in config.log.
A cross build configure for Windows with Debian stable aborts with an
error.

Avoiding unused arguments fixes this.

75ac231c67 gdb-xml: Fix size of EFER register on i386 architecture when debugged by GDB
Before this commit, there were contradictory descriptions about size of EFER
register.
Line 113 says the size is 8 bytes.
Line 129 says the size is 4 bytes.

As a result, when GDB is debugging an OS running on QEMU, the GDB cannot
read 'g' packets correctly. This 'g' packet transmits values of each
registers of machine emulated by QEMU to GDB. QEMU, the packet sender,
assign 4 bytes for EFER in 'g' packet based on the line 113.
GDB, the packet receiver, extract 8 bytes for EFER in 'g' packet based on
the line 129. Therefore, all registers located behind EFER in 'g' packet
has been shifted 4 bytes in GDB.

After this commit, GDB can read 'g' packets correctly.

When we implemented the PAN support we theoretically wanted
to support it for both AArch32 and AArch64, but in practice
several bugs made it essentially unusable with an AArch32
guest. Fix all those problems:

    - Use CPSR.PAN to check for PAN state in aarch32 mode
    - throw permission fault during address translation when PAN is
      enabled and kernel tries to access user acessible page
    - ignore SCTLR_XP bit for armv7 and armv8 (conflicts with SCTLR_SPAN).

d7ef5e16a1 hw/arm/boot: Set SCR_EL3.HXEn when booting kernel
When we direct boot a kernel on a CPU which emulates EL3, we need to
set up the EL3 system registers as the Linux kernel documentation
specifies:
     https://www.kernel.org/doc/Documentation/arm64/booting.rst

For CPUs with FEAT_HCX support this includes:
    - SCR_EL3.HXEn (bit 38) must be initialised to 0b1.

but we forgot to do this when implementing FEAT_HCX, which would mean
that a guest trying to access the HCRX_EL2 register would crash.

2b39abb2d6 hw/arm/boot: Set SME and SVE EL3 vector lengths when booting kernel
When we direct boot a kernel on a CPU which emulates EL3, we need
to set up the EL3 system registers as the Linux kernel documentation
specifies:
 https://www.kernel.org/doc/Documentation/arm64/booting.rst

For SVE and SME this includes:
    - ZCR_EL3.LEN must be initialised to the same value for all CPUs the
      kernel is executed on.
    - SMCR_EL3.LEN must be initialised to the same value for all CPUs the
      kernel will execute on.

Although we are technically compliant with this, the "same value" we
currently use by default is the reset value of 0.  This will end up
forcing the guest kernel's SVE and SME vector length to be only the
smallest supported length.

Initialize the vector length fields to their maximum possible value,
which is 0xf. If the implementation doesn't actually support that
vector length then the effective vector length will be constrained
down to the maximum supported value at point of use.

This allows the guest to use all the vector lengths the emulated CPU
supports (by programming the _EL2 and _EL1 versions of these
registers.)

target/loongarch: Fix raise_mmu_exception() set wrong exception_index
When the address is invalid address, We should set exception_index
according to MMUAccessType, and EXCCODE_ADEF need't update badinstr.
Otherwise, The system enters an infinite loop. e.g:
run test.c on system mode
test.c:
    #include<stdio.h>

    void (*func)(int *);

    int main()
    {
        int i = 8;
        void *ptr = (void *)0x4000000000000000;
        func = ptr;
        func(&i);
        return 0;
    }

16c81dd563 linux-user: always translate cmsg when recvmsg
It's possible that a message contains both normal payload and ancillary
data in the same message, and even if no ancillary data is available
this information should be passed to the target, otherwise the target
cmsghdr will be left uninitialized and the target is going to access
uninitialized memory if it expects cmsg.

Always call the function that translate cmsg when recvmsg, because that
function should be empty-cmsg-safe (it creates an empty cmsg in the
target).

The glibc on the hppa platform uses the "iitlbp %r0,(%sr0, %r0)"
assembler instruction as ABORT_INSTRUCTION.
If this (in userspace context) illegal assembler statement is found,
dump the registers and report the failure to userspace the same way as
the Linux kernel on physical hardware.

For other illegal instructions report TARGET_ILL_ILLOPC instead of
TARGET_ILL_ILLOPN as si_code.

Additionally add the missing EXCP_BREAK exception handler which occurs
when the "break x,y" assembler instruction is executed and report
EXCP_ASSIST traps.

Commit 2e53b0b450 ("hw/nvme: Use ioeventfd to handle doorbell

This patch changes the sq/cq timers to bottom halfs and instead of
calling nvme_post_cqes() immediately (causing an interrupt per cqe), we
defer the call.

4e4fa6c12d accel/tcg: Complete cpu initialization before registration
Delay cpu_list_add until realize is complete, so that cross-cpu
interaction does not happen with incomplete cpu state.  For this,
we must delay plugin initialization out of tcg_exec_realizefn,
because no cpu_index has been assigned.

Fixes a problem with cross-cpu jump cache flushing, when the
jump cache has not yet been allocated.

Fixes: a976a99a29 ("include/hw/core: Create struct CPUJumpCache")

cc30dc441b target/openrisc: Use cpu_unwind_state_data for mfspr
Since we do not plan to exit, use cpu_unwind_state_data
and extract exactly the data requested.

This is a bug fix, in that we no longer clobber dflag.

Consider:

        l.j       L2         // branch
        l.mfspr   r1, ppc    // delay

L1:     boom
L2:     l.lwa     r3, (r4)

Here, dflag would be set by cpu_restore_state (because that is the current
state of the cpu), but but not cleared by tb_stop on exiting the TB
(because DisasContext has recorded the current value as zero).

The next TB begins at L2 with dflag incorrectly set.  If the load has a
tlb miss, then the exception will be delivered as per a delay slot:
with DSX set in the status register and PC decremented (delay slots
restart by re-executing the branch). This will cause the return from
interrupt to go to L1, and boom!
