- gcc(1) fails to build usr.bin/dtc
- lack of WITH_GNUCXX=1 causes cc1plus(1) calls to fail
- u-boot fails to build with clang (hard-coded gcc(1) calls)
Implement the proper incantation of WITH_/WITHOUT_ knobs
to get arm snapshot builds working again.
Since the cc(1) binary is no longer expected to be clang(1),
remove the chroot(8) post-install cc(1) overwrite.

- These were needed on armv4/5 (VIVT cache), not needed on armv6.
- The wbinv_all call can't be used on SMP systems; cache operations by
set/way are not broadcast to other cores.
- The TLB maintenance operations needed for pmap_growkernel() happen in
pmap_grow_l2_bucket(), so there's no need to flush all TLB entries at
the end.
- There may not be any need for the TLB flush at the beginning of
pmap_release(), but it's left in for now pending more investigation.

WITHOUT_CLANG_IS_CC=1, it appears WITHOUT_CLANG=1 must
also be set.
While here, reorder the lines to put the WITH_* and
WITHOUT_* entries on the same line.

De-virtualize UMA zone pf_mtag_z and move to global initialization part.
The m_tag struct does not know about vnet context and the pf_mtag_free()
callback is called unaware of current vnet. This causes a panic.

Since <sys/capsicum.h> does not comply to any standards, standards-compliant
applications do not include it and it is not useful to restrict what is
exposed depending on the requested standard.
In addition, the use of types like u_int makes the header fail in strict
standards compliance modes anyway.
post-open/create directory attributes. This allows the RPC to
name cache the newly created file and reduces the lookup RPC
count by about 10% for software builds.

For 10 years, the "DIALUP <tty>, <user>" message has required having a
hostname (-h) instead of not having a hostname; therefore, it is never
logged. Given that dialup is obsolete and this has not been fixed, remove
the log message.
Note that LOGALL, which is defined by default, logs a message for all
logins, including dialup logins.
attributes. This allows the client to cache directory names
when they are looked up, reducing the Lookup RPC count by
about 40% for software builds.

we're preventing now with this policy. However, these edge cases
should be rare and all that set MK_FOO directly.
WITH_FOO and WITHOUT_FOO both being defined now result in the
non-default behavior happening silently. Users needing determinism
here fall into the edge case exception for MK_FOO setting.
code from the rest. Include bsd.opts.mk in bsd.own.mk to preserve
current behavior. Future revisions will replace the inclusion of
bsd.own.mk elsewhere with bsd.opts.mk or a more appropriate new
file that's still being finalized.
building clang and/or gcc as the bootstrap compiler. Normally, the
default compiler is used. WITH_CLANG_BOOTSTRAP and/or
WITH_GCC_BOOTSTRAP will enable building these compilers as part
bootstrap phase. WITH/WITHOUT_CLANG_IS_CC controls which compiler is
used by default for the bootstrap phase, as well as which compiler is
installed as cc. buildworld now successfully completes building the
cross compiler with WITHOUT_CLANG=t and WITHOUT_GCC=t and produces a
built system with neither of these included.
Similarlly, MK_BINUTILS_BOOTSTRAP controls whether binutils is built
during this phase.
WITHOUT_CROSS_COMPILER will now force MK_BINUTILS_BOOTSTRAP=no,
MK_CLANG_BOOTSTRAP=no and MK_GCC_BOOTSTRAP=no.
BOOTSTRAP_COMPILER was considered, but rejected, since pc98 needs both
clang and gcc to bootstrap still. It should be revisisted in the
future if this requirement goes away. Values should be gcc, clang or
none. It could also be a list.
The odd interaction with Xfoo cross/external tools needs work, but
is beyond the scope of this change as well.
worse when filling up a device and then trying to erase files to make
space. Without enough space, you can't do that. Also, ensure that the
metadata writes don't generate ENOSPC. They will be retried later
since the buffers are still dirty...
