These may have ccache in them or -target/--sysroot from external
compiler or SYSTEM_COMPILER support. Many ports do not support
a CC with spaces in it, such as emulators/virtualbox-ose-kmod.
Passing --sysroot to ports makes no sense as ports doesn't support
--sysroot currently.
If these variables need to be overridden for ports then they can
be set in make.conf or passed as make arguments.

promote memory as I am not sure all the demotion cases are handled, however
it is useful to implement pmap_page_set_memattr. This is used, for example,
when mapping uncached memory for bus_dma(9).
pmap_page_set_memattr needs to demote the DMAP region as on ARM we need to
ensure all mappings to the same physical address have the same attributes.

Suppose that ktrace is performed on 32bit binary running on 64bit
host. In this case, the kernel records are 64bit, while utrace
records from rtld and malloc are 32bit. Make kdump useful to see
decoded utrace data in that case.

Now that we've updated the prototypes of the basename(3) and dirname(3)
functions to conform to POSIX, let's go ahead and reimplement dirname(3)
in such a way that it's thread-safe, but also guaranteed to succeed. C
libraries like glibc, musl and the one that's part of Solaris already
follow such an approach.
Move the existing implementation to another source file,
freebsd11_dirname.c to keep existing users of the API that pass in a
constant string happy, using symbol versioning.
Put a new version of the function in dirname.c, obtained from CloudABI's
C library. This version scans through the pathname string from left to
right, normalizing it, while discarding the last pathname component.

Correctly limit npairs passed to vtnet_ctrl_mq_cmd. This ensures that
VQ_ALLOC_INFO_INIT is called with the correct value, preventing the system
from hanging when max_virtqueue_pairs > VTNET_MAX_QUEUE_PAIRS.
Add new sysctl requested_vq_pairs which allow the user to configure
the requested number of virtqueue pairs. The actual value will still take
into account the system limits.
Also missing sysctls for the current tunables so their values can be seen.

CloudABI executables already provide support for passing in vDSOs. This
functionality is used by the emulator for OS X to inject system call
handlers. On FreeBSD, we could use it to optimize calls to
gettimeofday(), etc.
Though I don't have any plans to optimize any system calls right now,
let's go ahead and already pass in a vDSO. This will allow us to
simplify the executables, as the traditional "syscall" shims can be
removed entirely. It also means that we gain more flexibility with
regards to adding and removing system calls.

With both of these flags, the backup was created via rename(dest, backup)
followed by rename(tmp, dest). This left the destination file missing
for a moment which contradicts the point of -S.
This fixes a race with installworld where PRECIOUSPROG and PRECIOUSLIB
files (which use -S for installation) would briefly be missing. In the
case of installing rtld with parallel installworld it could render an
error due to not having rtld present to run install/cp in another
process.

On all the other architectures, this function can also be called on the

in the PCB, but also patch up the register itself. Otherwise it will not
become active and will simply become overwritten by the next switch.
