Some Elantech trackpads have a mangled HID report descriptor, which
reads as having an incorrect input size (i.e. < IETP_REPORT_LEN_LO).
If the input size is incorrect, load a dummy report descriptor.

According to the Intel manual
https://www.intel.com/content/dam/www/public/us/en/documents/manuals/64-ia-32-architectures-software-developer-vol-3b-part-2-manual.pdf
the Thermal Status (0) and Thermal Status Log (1) bits report only a
high temperature on the CPU, not a critical temperature as suggested in
the coretemp driver. Check the Critical Temperature Log (5) instead.
The critical temperature waives guarantees of correct function,
therefore the CPU could have for example written some wrong values into
memory at that point and the OS should be stopped ASAP as the state is
no longer reliable.

Casting to int truncates size on some platforms, resulting swab not
copying all the data. Cast len to size_t to avoid right shifting a
signed value: we know here it's > 0, so we can safely cast it w/o losing
precision.

In addition, be more careful with signedness of char pointers and
temporaries. Downgrade tmp from unsigned long to unsigned char since
we're only reading and writing characters.

During testing of exporting file systems in jails, I
noticed that the export structures on a mount
were not being free'd when the mount is dismounted.

This bug appears to have been in the system for a
very long time.  It would have resulted in a slow memory
leak when exported file systems were dismounted.

Prior to r362158, freeing the structures during dismount
would not have been safe, since VFS_CHECKEXP() returned
a pointer into an export structure, which might still have been
used by the NFS server for an in-progress RPC when the file system
is dismounted.  r362158 fixed this, so it should now be safe
to free the structures in vfs_mount_destroy(), which is what
this patch does.

- remove Huawei 3G E3131 (E3131_INIT):
	- frees up 0x1505/0x14fe shared IDs => product is EOL (since...)
	- 3G networks are shutdown/scheduled
	- E3131 devices will still work the same via scsi_huawei_eject2

Switch the now added E5573Cs322_ECM (0x14db) as well per default to NCM.
With this patch we default all devices to simple NCM mode to avoid the
problem and get a consistent reliable behavior. No matter what firmware
version and provider mix are involved.

Rationale:
Even the bigger SOC shows under complex load in ECM (double-nat) mode
the same performance drop from 25Mbit to 2Mbit Line Speed, similar to E3372h.
Reason: Thermal problems (reported via serial debug interface in ACM Mode)
after 2-3 minutes load.

Fix the root cause and bundle a working firmware is out of reach because
Huawei sells the same hardware, different (crippled) firmware versions
at different price points in different markets as strategy.

This fixes armv7 kernel build with gcc12.

Add missing logic to allow in-kernel VFP usage for ARMv7 NEON.
The implementation is strongly based on arm64 code.
It introduces a family of fpu_kern_* functions to enable the usage
of VFP instructions in kernel.
Apart from that the existing armv7 VFP logic was modified,
taking into account that the state of the VFP registers can now
be modified in the kernel.

Writes on UFS through a mapped region do not allocate disk blocks in
holes immediately. The blocks are allocated when the pages are paged out
first time.

This breaks the algorithm in vn_bmap_seekhole() and ufs_bmap_seekdata(),
because VOP_BMAP() reports hole for the place which already contains a
valid data.

Clean the pages before doing VOP_BMAP() in the affected functions.  In
principle, we could clean less by only requesting clean starting from
the offset, but it is probably not very important.

Can be used to count the number of hardware threads in the cpu set.

For example:
$ cpuset -g -p $$
pid 2440 mask: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16,

35, 36, 37, 38, 39
pid 2440 domain policy: first-touch mask: 0, 1
$ cpuset -g --count -p $$
40

The intent is to replace calls to sysctl hw.ncpu and kern.smp.cpus which
can be found in the tree, which are not adequate given existence of
cpusets.

Right now only -g -p combination is supported to reduce complexity.
As anything else errors out, this can be expanded later as needed.
