For debug exceptions due to breakpoints or the BKPT instruction which
are taken to AArch32, the Fault Address Register is architecturally
UNKNOWN. We were using that as license to simply not set
env->exception.vaddress, but this isn't correct, because it will
expose to the guest whatever old value was in that field when
arm_cpu_do_interrupt_aarch32() writes it to the guest IFSR. That old
value might be a FAR for a previous guest EL2 or secure exception, in
which case we shouldn't show it to an EL1 or non-secure exception
handler. It might also be a non-deterministic value, which is bad
for record-and-replay.
Clear env->exception.vaddress before taking breakpoint debug
exceptions, to avoid this minor information leak.

Now that we have a helper function specifically for the BRK and
BKPT instructions, we can set the exception.fsr there rather
than in arm_cpu_do_interrupt_aarch32(). This allows us to
use our new arm_debug_exception_fsr() helper.
In particular this fixes a bug where we were hardcoding the
short-form IFSR value, which is wrong if the target exception
level has LPAE enabled.

When a debug exception is taken to AArch32, it appears as a Prefetch
Abort, and the Instruction Fault Status Register (IFSR) must be set.
The IFSR has two possible formats, depending on whether LPAE is in
use. Factor out the code in arm_debug_excp_handler() which picks
an FSR value into its own utility function, update it to use
arm_fi_to_lfsc() and arm_fi_to_sfsc() rather than hard-coded constants,
and use the correct condition to select long or short format.
In particular this fixes a bug where we could select the short
format because we're at EL0 and the EL1 translation regime is
not using LPAE, but then route the debug exception to EL2 because
of MDCR_EL2.TDE and hand EL2 the wrong format FSR.

The MDCR_EL2.TDE bit allows the exception level targeted by debug
exceptions to be set to EL2 for code executing at EL0. We handle
this in the arm_debug_target_el() function, but this is only used for
hardware breakpoint and watchpoint exceptions, not for the exception
generated when the guest executes an AArch32 BKPT or AArch64 BRK
instruction. We don't have enough information for a translate-time
equivalent of arm_debug_target_el(), so instead make BKPT and BRK
call a special purpose helper which can do the routing, rather than
the generic exception_with_syndrome helper.

Linux does not detect a break from this IMX serial driver as a magic
sysrq. Nor does it note a break in the port error counts.
The former is because the Linux driver uses the BRCD bit in the USR2
register to trigger the RS-232 break handler in the kernel, which is
where sysrq hooks in. The emulated UART was not setting this status
bit.
The latter is because the Linux driver expects, in addition to the BRK
bit, that the ERR bit is set when a break is read in the FIFO. A break
should also count as a frame error, so add that bit too.

If the GIC has the security extension support enabled, then a
non-secure access to ICC_PMR must take account of the non-secure
view of interrupt priorities, where real priorities 0x00..0x7f
are secure-only and not visible to the non-secure guest, and
priorities 0x80..0xff are shown to the guest as if they were
0x00..0xff. We had the logic here wrong:
* on reads, the priority is in the secure range if bit 7
is clear, not if it is set
* on writes, we want to set bit 7, not mask everything else
Our ICC_RPR read code had the same error as ICC_PMR.
(Compare the GICv3 spec pseudocode functions ICC_RPR_EL1
and ICC_PMR_EL1.)

In OE project 4.15 linux kernel boot hang was observed under
single cpu aarch64 qemu. Kernel code was in a loop waiting for
vtimer arrival, spinning in TC generated blocks, while interrupt
was pending unprocessed. This happened because when qemu tried to
handle vtimer interrupt target had interrupts disabled, as
result flag indicating TCG exit, cpu->icount_decr.u16.high,
was cleared but arm_cpu_exec_interrupt function did not call
arm_cpu_do_interrupt to process interrupt. Later when target
reenabled interrupts, it happened without exit into main loop, so
following code that waited for result of interrupt execution
run in infinite loop.
To solve the problem instructions that operate on CPU sys state
(i.e enable/disable interrupt), and marked as DISAS_UPDATE,
should be considered as DISAS_EXIT variant, and should be
forced to exit back to main loop so qemu will have a chance
processing pending CPU state updates, including pending
interrupts.
This change brings consistency with how DISAS_UPDATE is treated
in aarch32 case.

Commit d4e5ec877 already fixed things to work around Python 3's
lame bug of having LC_ALL=C not be 8-bit clean, when parsing the
main QMP qapi files; but failed to do likewise in the tests
directory. As a result, running 'LC_ALL=C make check' fails on
escape-too-big and unicode-str when using python 3 with a nasty
stack trace instead of the intended graceful error message that
QAPI doesn't yet support 8-bit data (the two tests contain
Unicode é, when parsed in UTF-8; they represent something
different when parsed in a proper single-byte C locale, but that
doesn't matter to the error message printed out, provided that
brain-dead Python hasn't first choked on the input instead of
being 8-bit clean).
Ideally, we'd teach the qapi generator scripts to automatically
slurp things in using UTF-8 regardless of locale, and to honor
content that is not limited to 7 bit data rather than gracefully
erroring out; but until then, since our graceful error depends
on python parsing 8-bit data (even if nothing we generate uses
8-bit data), our quick fix is to use the right locale when
running these tests.

Use the correct printf formats, so that a 32-bit compile doesn't spit
out lots of warnings about %lx being incompatible with uint64_t.

Our rule right now is to use <> for external headers,
"" for internal ones. The idea was to avoid conflicts
between e.g. a system file named <trace.h> and an
internal one by the same name.
Unfortunately we use -I compiler flag so it does not
help: a system file doing #include <trace.h> will
still pick up ours first.
To fix, switch to -iquote which is supported by both
gcc and clang and only affects #include "" directives.
As a side effect, this catches any future uses of
#include <> for internal headers.

Testing the exit code only once after a whole group of tests has
completed is not enough, it catches errors only in the very last qemu
invocation. We need to have the check after each qemu run.
The logging and diff with the reference output is still done once per
group to keep things more managable. This is not a problem because the
log file accumulates the output of all runs.

I couldn't find a case where this prevents something bad from happening
that isn't already caught by other checks, but let's err on the safe
side and check that mh_header_addr is as expected.

The code path where mh_load_end_addr is non-zero in the Multiboot
header checks that mh_load_end_addr >= mh_load_addr and so
mb_load_size is checked. However, mb_load_size is not checked when
calculated from the file size, when mh_load_end_addr is 0.
If the kernel binary size is larger than can fit in the address space
after load_addr, we ended up with a kernel_size that is smaller than
load_size, which means that we read the file into a too small buffer.
Add a check to reject kernel files with such Multiboot headers.

This occurs when symbols haven't been loaded first, i.e. neither a
QEMU binary was loaded nor a QEMU process was attached first. Let's
better inform the user of how to fix the issue themselves in order
to avoid more reports.
