monitor: temporary fix for dead-lock on event recursion
With a Spice port chardev, it is possible to reenter
monitor_qapi_event_queue() (when the client disconnects for
example). This will dead-lock on monitor_lock.
Instead, use some TLS variables to check for recursion and queue the
events.
Fixes:

Note that error report is now moved to the first caller, which may
receive an error for a recursed event. This is probably fine (95% of
callers use &error_abort, the rest have NULL error and ignore it)

linux-user: ppc64: don't use volatile register during safe_syscall
r11 is a volatile register on PPC as per calling conventions.
The safe_syscall code uses it to check if the signal_pending
is set during the safe_syscall. When a syscall is interrupted
on return from signal handling, the r11 might be corrupted
before we retry the syscall leading to a crash. The registers
r0-r13 are not to be used here as they have
volatile/designated/reserved usages.
Change the code to use r14 which is non-volatile.
Use SP+16 which is a slot for LR, for save/restore of previous value
of r14. SP+16 can be used, as LR is preserved across the syscall.
Steps to reproduce:
On PPC host, issue `qemu-x86_64 /usr/bin/cc -E -`
Attempt Ctrl-C, the issue is reproduced.

This is because of a reset ordering problem -- the TZ MPC
resets after the CPU, but an M-profile CPU's reset function
includes memory loads to get the initial PC and SP, which
then go through an MPC that hasn't yet been reset.
The simplest fix for this is to zero the LUT when we
initialize the data, which will result in the MPC's
translate function giving the right answers for these
early memory accesses.

file-posix: Fix write_zeroes with unmap on block devices
The BLKDISCARD ioctl doesn't guarantee that the discarded blocks read as
all-zero afterwards, so don't try to abuse it for zero writing. We try
to only use this if BLKDISCARDZEROES tells us that it is safe, but this
is unreliable on older kernels and a constant 0 in newer kernels. In
other words, this code path is never actually used with newer kernels,
so we don't even try to unmap while writing zeros.
This patch removes the abuse of discard for writing zeroes from
file-posix and instead adds a new function that uses interfaces that are
actually meant to deallocate and zero out at the same time. Only if
those fail, it falls back to zeroing out without unmap. We never fall
back to a discard operation any more that may or may not result in
zeros.

Unfortunately this change has global impact across the entire test suite
and means that when tests fail for unexpected reasons, the message is
not displayed on stderr. eg when using &error_abort in a call the test
merely prints
Unexpected error in qcrypto_tls_session_check_certificate() at crypto/tlssession.c:280:
and the actual error message is hidden, making it impossible to diagnose
the failure. This is especially problematic in CI or build systems where
it isn't possible to easily pass the --debug-log flag to tests and
re-run with the test log visible.
This change makes the previous big hammer much more nuanced, providing a
flag in the stub error_vprintf() that can used on a per-test basis to
silence the errors. Only the test-vmstate silences errors initially.

block/file-posix: add bdrv_attach_aio_context callback for host dev and cdrom
In
ed6e2161 ("linux-aio: properly bubble up errors from initialzation"),
I only added a bdrv_attach_aio_context callback for the bdrv_file
driver. There are several other drivers that use the shared
aio_plug callback, though, and they will trip the assertion added to
aio_get_linux_aio because they did not call aio_setup_linux_aio first.
Add the appropriate callback definition to the affected driver
definitions.
Fixes:

target/arm: Escalate to correct HardFault when AIRCR.BFHFNMINS is set
When we escalate a v8M exception to HardFault, if AIRCR.BFHFNMINNS is
set then we need to decide whether it should become a secure HardFault
or a nonsecure HardFault. We should always escalate to the same
target security state as the original exception. The current code
tries to test this using the 'secure' bool, which is not right because
that flag indicates whether the target security state only for
banked exceptions; the effect was that we were incorrectly escalating
always-secure exceptions like SecureFault to a nonsecure HardFault.
Fix this by defining, logging and using a new 'targets_secure' bool
which tracks the condition we actually want.

the min_sparse convert parameter can overflow (e.g. -S 1024G)
in the conversion from int64_t to int resulting in a negative
min_sparse parameter. Avoid this by limiting the valid parameters
to sane values. In fact anything exceeding the convert buffer size
is also pointless. While at it also forbid values that are non

hw/intc/exynos4210_gic: Turn instance_init into realize function
The instance_init function of the "exynos4210.gic" device creates a
new "arm_gic" device and immediately realizes it with qdev_init_nofail().
This will leave a lot of object in the QOM tree during introspection of
the "exynos4210.gic" device, e.g. reproducible by starting QEMU like this:
qemu-system-aarch64 -M none -nodefaults -nographic -monitor stdio
And then by running "info qom-tree" at the HMP monitor, followed by
"device_add exynos4210.gic,help" and finally checking "info qom-tree"
again.
Also note that qdev_init_nofail() can exit QEMU in case of errors - and
this must never happen during an instance_init function, otherwise QEMU
could terminate unexpectedly during introspection of a device.
Since most of the code that follows the qdev_init_nofail() depends on
the realized "gicbusdev", the easiest solution to the problem is to
turn the whole instance_init function into a realize function instead.

hw/arm/spitz: Move problematic nand_init() code to realize function
nand_init() does not only create the NAND device, it also realizes
the device with qdev_init_nofail() already. So we must not call
nand_init() from an instance_init function like sl_nand_init(),
otherwise we get superfluous NAND devices in the QOM tree after
introspecting the 'sl-nand' device. So move the nand_init() to the
realize function of 'sl-nand' instead.

target/arm: Correctly handle overlapping small MPU regions
To correctly handle small (less than TARGET_PAGE_SIZE) MPU regions,
we must correctly handle the case where the address being looked
up hits in an MPU region that is not small but the address is
in the same page as a small region. For instance if MPU region
1 covers an entire page from 0x2000 to 0x2400 and MPU region
2 is small and covers only 0x2200 to 0x2280, then for an access
to 0x2000 we must not return a result covering the full page
even though we hit the page-sized region 1. Otherwise we will
then cache that result in the TLB and accesses that should
hit region 2 will incorrectly find the region 1 information.
Check for the case where we miss an MPU region but it is still
within the same page, and in that case narrow the size we will
pass to tlb_set_page_with_attrs() for whatever the final
outcome is of the MPU lookup.

monitor: Fix unsafe sharing of @cur_mon among threads
@cur_mon is null unless the main thread is running monitor code, either
HMP code within monitor_read(), or QMP code within
monitor_qmp_dispatch().
Use of @cur_mon outside the main thread is therefore unsafe.
Most of its uses are in monitor command handlers. These run in the main
thread.
However, there are also uses hiding elsewhere, such as in
error_vprintf(), and thus error_report(), making these functions unsafe
outside the main thread. No such unsafe uses are known at this time.
Regardless, this is an unnecessary trap. It's an ancient trap, though.
More recently, commit
cf869d53172 "qmp: support out-of-band (oob)
execution" spiced things up: the monitor I/O thread assigns to @cur_mon
when executing commands out-of-band. Having two threads save, set and
restore @cur_mon without synchronization is definitely unsafe. We can
end up with @cur_mon null while the main thread runs monitor code, or
non-null while it runs non-monitor code.
We could fix this by making the I/O thread not mess with @cur_mon, but
that would leave the trap armed and ready.
Instead, make @cur_mon thread-local. It's now reliably null unless the
thread is running monitor code.
