Require a command to exec or a pid to target and update usage and the
manpage to make this more clear.
It makes no sense to invoke a procctl(2) command on the current process
only to exit. Users are sometimes confused about how proccontrol works
and think it effects their shell environment when invoked without a
target. Disallowing this nonsensical behavior and clarifiying usage
will hopefully reduce confusion.

Originally, a SYN-cache entry was always allocated and later freed,
when not needed anymore. Then the allocation was avoided, when no
SYN-cache entry was needed, and a copy on the stack was used.
But the logic regarding freeing was not updated.
This patch doesn't re-check conditions (which may have changed) when
deciding to insert or free the entry, but uses the result of
the earlier check.
This simplifies the code and improves also consistency.

GNU/Linux has historically had the following two resolver prototypes:
1. Elf_Addr(uint64_t, void *)
2. Elf_Addr(uint64_t, void *, void *)
For the former, AT_HWCAP is passed in the first argument, and NULL in
the second. For the latter, AT_HWCAP is still passed, and the second
argument is a pointer to their home-grown __riscv_hwprobe function.
Should they want to use the third argument in future, they'll have to
introduce yet another prototype to allow for later expansion, and then
all users will have to check whether the second argument is NULL to know
if the third argument really exists. This is all rather silly and will
surely prove fun in the face of type-checking CFI.
Instead, be like arm64 and just define all 8 possible general purpose
register arguments up front. To naive source code that forgets non-Linux
OSes exist this will be compatible with prototype 1 above, since the
second argument will be 0 and it won't look further (though should we
start using the second argument for something that wouldn't be true any
more and it might think it's __riscv_hwprobe, but that incompatibility
is one we can defer committing to, and can choose to never adopt).
Until the standard interface for querying extension information[1] is
settled and implemented in FreeBSD there's not much you can do in a
resolver other than use HWCAP_ISA_B, but this gets the infrastructure in
place for when that day comes.

Currently we pass the raw pointer to the on-stack auxargs. This can
legitimately have fewer than AT_COUNT entries, so the use of
__min_size(AT_COUNT), i.e. static AT_COUNT, is inaccurate, and also
needlessly forces the callee to iterate over the elements to find the
entry for a given type. Instead we can just pass aux_info like we use
for everything else.
Note that the argument has been left unused by every callee since its
introduction in 4352999e0e ("Pass CPUID[1] %edx (cpu_feature), %ecx
(cpu_feature2) and CPUID[7].%ebx (cpu_stdext_feature), %ecx
(cpu_stdext_feature2) to the ifunc resolvers on x86.")

Don't provide default linkage for jemalloc 3.0 compatability symbols.
We stopped declaring these interfaces with the introduction of jemalloc
4.0 prior to FreeBSD 11.0. Any code using them would have had to
declare them manually so stop declaring them and export the symbols
directly for compatability. Arguably they should be x86 only as they
were never declared on other Tier-1 architectures.

* We can build the non-VHE code with branch protection, it is already
build as such in the module.
* Use the correct file name for the non-VHE exception .o file.
When FEAT_VHE is present the HCR_EL2 E2H field will be implemented. Try
setting this and checking if it's still set to decide if we can boot
into VHE mode or not.
When it is implemented the kernel will boot into EL2 rather than EL1
it currently boots to. The parts of the kernel that need to know if
they are in EL1 or EL2 have been updated other than the CoreSight
driver as there doesn't appear to be any way to currently use it and
it will be updated soon with the new HWT framework.

RFC8275 defines a new attribute as an extension to NFSv4.2
called MODE_UMASK. This patch adds support for this attribute
to the NFSv4.2 client and server.
Since FreeBSD applies the umask above the VFS/VOP layer,
this attribute does not actually have any effect on the
handling of ACL inheritance, which is what it is designed for.
However, future changes to NFSv4.2 require support of it,
so this patch does that, resulting in behaviour identcal to
the mode attribute already supported.
