In commit 84d43d2e82 we rearranged the logging of errors in
process_mapc(), and inadvertently dropped the trailing newlines
from the log messages. Restore them. The same commit also
attempted to switch the ICID printing to hex (which is how we
print ICIDs elsewhere) but only did half the job, adding the
0x prefix but leaving the format string at %d; correct to %x.

Philippe found cases where the 0x%d format string was used, leading to
misleading output. The patches look harmless and could save people time, so I
think it's worth including them in 7.0.

Some versions of Windows hang on reboot if their TSC value is greater
than 2^54. The calibration of the Hyper-V reference time overflows
and fails; as a result the processors' clock sources are out of sync.
The issue is that the TSC _should_ be reset to 0 on CPU reset and
QEMU tries to do that. However, KVM special cases writing 0 to the
TSC and thinks that QEMU is trying to hot-plug a CPU, which is
correct the first time through but not later. Thwart this valiant
effort and reset the TSC to 1 instead, but only if the CPU has been
run once.
For this to work, env->tsc has to be moved to the part of CPUArchState
that is not zeroed at the beginning of x86_cpu_reset.

Some AMD processors expose the PKRU extended save state even if they do not have
the related PKU feature in CPUID. Worse, when they do they report a size of
64, whereas the expected size of the PKRU extended save state is 8, therefore
the esa->size == eax assertion does not hold.
The state is already ignored by KVM_GET_SUPPORTED_CPUID because it
was not enabled in the host XCR0. However, QEMU kvm_cpu_xsave_init()
runs before QEMU invokes arch_prctl() to enable dynamically-enabled
save states such as XTILEDATA, and KVM_GET_SUPPORTED_CPUID hides save
states that have yet to be enabled. Therefore, kvm_cpu_xsave_init()
needs to consult the host CPUID instead of KVM_GET_SUPPORTED_CPUID,
and dies with an assertion failure.
When setting up the ExtSaveArea array to match the host, ignore features that
KVM does not report as supported. This will cause QEMU to skip the incorrect
CPUID leaf instead of tripping the assertion.

In the physical machine environment, when a SRAR error occurs,
the IA32_MCG_STATUS RIPV bit is set, but qemu does not set this
bit. When qemu injects an SRAR error into virtual machine, the
virtual machine kernel just call do_machine_check() to kill the
current task, but not call memory_failure() to isolate the faulty
page, which will cause the faulty page to be allocated and used
repeatedly. If used by the virtual machine kernel, it will cause
the virtual machine to crash

is documented. Let's document QEMU_PLUGIN.

There appears to be a bug in the s390 hardware-accelerated version of
zlib distributed with Ubuntu 20.04, which makes our test
/i386/migration/multifd/tcp/zlib hit an assertion perhaps one time in
10. Fortunately zlib provides an escape hatch where we can disable the
hardware-acceleration entirely by setting the environment variable
DFLTCC to 0. Do this on all our CI which runs on s390 hosts, both our
custom gitlab runner and also the Travis hosts.

The MIPS n32 ABI is basically n64 with the address space (i.e. pointer
width) shrinked to 32 bits. Meanwhile the current code treats it as
o32-like based on TARGET_ABI_BITS, which causes problems with n32
syscalls utilizing 64-bit offsets, like pread64, affecting most (if not
all) recently built n32 binaries.
This partially solves issue #909 ("qemu-mipsn32(el) user mode emulator
fails to execute any recently built n32 binaries"); with this change
applied, the built qemu-mipsn32el is able to progress beyond the
pread64, and finish _dl_start_user for the "getting ld.so load libc.so"
case. The program later dies with SIGBUS, though, due to _dl_start_user
not maintaining stack alignment after removing ld.so itself from argv,
and qemu-user starting to enforce alignment recently, but that is
orthogonal to the issue here; the more common case of chrooting is
working, verified with my own-built Gentoo n32 sysroot. (Depending on
the exact ISA used, one may have to explicitly specify QEMU_CPU, which
is the case for my chroot.)
