ocfs2 quota recovery allocates a bitmap buffer with kmalloc and does not
fully initialize it. This can lead to use of uninitialized bits during
quota recovery from a corrupted filesystem image.
Use kzalloc instead to ensure the bitmap is zero-initialized.

Reproduce with GCC 13.3.0:
$ cd tools/accounting
$ make
This emits:
getdelays.c: In function `format_timespec':
getdelays.c:218:67: warning: `:' directive output may be truncated writing 1 byte into a region of size between 0 and 16 [-Wformat-truncation=]
218 | snprintf(buffer, sizeof(buffer), "%04d-%02d-%02dT%02d:%02d:%02d",
|
getdelays.c:218:9: note: `snprintf' output between 20 and 72 bytes into a destination of size 32
The problem is that %04d and %02d specify minimum field widths only. GCC
cannot prove that formatting tm_year + 1900 and the other struct tm
fields will always fit in the fixed 32-byte buffer, so it warns about
possible truncation.
Fix this by replacing the manual snprintf() formatting with
strftime("%Y-%m-%dT%H:%M:%S", ...). That matches the data we already have
in struct tm, keeps the intended timestamp format, and avoids the warning
when building tools/accounting with GCC.

Replace strlen(fn) with strnlen(fn, NAME_MAX + 1) when validating the
final path component in __proc_create().
This preserves the existing name limit while bounding the length scan to
one byte past the maximum name length. Handle empty names separately, and
treat names longer than NAME_MAX as too long.

Add option --spdx-cxx-comments to not force C comments (/* */) for SPDX,
but allow also C++ comments (//).
As documented in aa19a176df, this is required for some old toolchains
still have older assembler tools which cannot handle C++ style comments.
This avoids forcing this for projects which vendored checkpatch.pl (e.g.
LTP or u-boot).

checkpatch.pl searches for .checkpatch.conf in $CWD, $HOME and
$CWD/.scripts. Allow passing a single directory via CHECKPATCH_CONFIG_DIR
environment variable (empty value is ignored). This allows to directly
use project configuration file for projects which vendored checkpatch.pl
(e.g. LTP or u-boot).
Although it'd be more convenient for user to have --conf-dir option
(instead of using environment variable), code would get ugly because
options from the configuration file needs to be read before processing
command line options with Getopt::Long.
While at it, document directories and environment variable in -h help
and HTML doc.

Hygon Family 18h CPUs are derived from AMD Family 17h (Zen1) silicon and
share the same erratum #1235: hardware may read a stale IsRunning=1 bit
during ICR write emulation and silently fail to generate an
AVIC_IPI_FAILURE_TARGET_NOT_RUNNING VM-Exit on the sending vCPU.
The absence of the VM-Exit causes KVM to miss the required wakeup of
blocking target vCPUs, leading to hung vCPUs and unbounded delays in
guest execution.
Extend the existing AMD Family 17h erratum #1235 workaround to also cover
Hygon Family 18h. With IPI virtualization disabled, KVM never sets
IsRunning=1 in the Physical ID table, so every non-self IPI generates a
VM-Exit and is correctly emulated.

When KVM_CAP_X86_APIC_BUS_CYCLES_NS is queried on a specific VM, return the
VM's configured APIC bus frequency, not KVM's default. Aside from the fact
that returning the default frequency is blatantly wrong if userspace has
changed the frequency, returning the configured frequency means userspace
can blindly trust the result, e.g. when filling PV CPUID information that
communicates the APIC bus frequency to the guest.
