strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().
Direct replacement is safe here since return value of -errno
is used to check for truncation instead of sizeof(dest).

Replace the (incorrect) external declarations by an inclusion of the
appropriate header file.
Semantically, the "src" parameters of the various fp_*() functions are
constant. However, they cannot actually be const as most of these
functions perform a normalization step first. As the fp_one constant
passed to fp_add() is already normalized, it is safe to cast away its
constness when making the function call.

- Fix the "bytes" output of the per_cpu stat file
The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the
accounting was not accurate. It is suppose to show how many used bytes are
still in the ring buffer, but even when the ring buffer was empty it would
still show there were bytes used.
- Fix a bug in eventfs where reading a dynamic event directory (open) and then
creating a dynamic event that goes into that diretory screws up the accounting.
On close, the newly created event dentry will get a "dput" without ever having
a "dget" done for it. The fix is to allocate an array on dir open to save what
dentries were actually "dget" on, and what ones to "dput" on close.

Pull cxl fixes from Dan Williams:
"A collection of regression fixes, bug fixes, and some small cleanups
to the Compute Express Link code.
The regressions arrived in the v6.5 dev cycle and missed the v6.6
merge window due to my personal absences this cycle. The most
important fixes are for scenarios where the CXL subsystem fails to
parse valid region configurations established by platform firmware.
This is important because agreement between OS and BIOS on the CXL
configuration is fundamental to implementing "OS native" error
handling, i.e. address translation and component failure
identification.
Other important fixes are a driver load error when the BIOS lets the
Linux PCI core handle AER events, but not CXL memory errors.
The other fixex might have end user impact, but for now are only known
to trigger in our test/emulation environment.
Summary:
- Fix multiple scenarios where platform firmware defined regions fail
to be assembled by the CXL core.
- Fix a spurious driver-load failure on platforms that enable OS
native AER, but not OS native CXL error handling.
- Fix a regression detecting "poison" commands when "security"
commands are also defined.
- Fix a cxl_test regression with the move to centralize CXL port
register enumeration in the CXL core.
- Miscellaneous small fixes and cleanups"

When the TSC_AUX MSR is virtualized, the TSC_AUX value is swap type "B"
within the VMSA. This means that the guest value is loaded on VMRUN and
the host value is restored from the host save area on #VMEXIT.
Since the value is restored on #VMEXIT, the KVM user return MSR support
for TSC_AUX can be replaced by populating the host save area with the
current host value of TSC_AUX. And, since TSC_AUX is not changed by Linux
post-boot, the host save area can be set once in svm_hardware_enable().
This eliminates the two WRMSR instructions associated with the user return
MSR support.

The checks for virtualizing TSC_AUX occur during the vCPU reset processing
path. However, at the time of initial vCPU reset processing, when the vCPU
is first created, not all of the guest CPUID information has been set. In
this case the RDTSCP and RDPID feature support for the guest is not in
place and so TSC_AUX virtualization is not established.
This continues for each vCPU created for the guest. On the first boot of
an AP, vCPU reset processing is executed as a result of an APIC INIT
event, this time with all of the guest CPUID information set, resulting
in TSC_AUX virtualization being enabled, but only for the APs. The BSP
always sees a TSC_AUX value of 0 which probably went unnoticed because,
at least for Linux, the BSP TSC_AUX value is 0.
Move the TSC_AUX virtualization enablement out of the init_vmcb() path and
into the vcpu_after_set_cpuid() path to allow for proper initialization of
the support after the guest CPUID information has been set.
With the TSC_AUX virtualization support now in the vcpu_set_after_cpuid()
path, the intercepts must be either cleared or set based on the guest
CPUID input.
