f53edc909e In init_dynamic_kenv(), ignore environment strings exceeding the
KENV_MNAMELEN + 1 + KENV_MVALLEN + 1 length limit to avoid buffer
overflow in getenv(). Currenly loader(8) doesn't limit the length of
environment strings.

68e0d7e06a Move from passing a wildcard boolean to a general set up lookup flags into
in_pcb_lport(), in_pcblookup_local(), and in_pcblookup_hash(), and similarly
for IPv6 functions.  In the future, we would like to support other flags
relating to locking strategy.

This change doesn't appear to modify the KBI in practice, as callers already
passed in INPLOOKUP_WILDCARD rather than a simple boolean.

82a5be494a A number of quite incremental refinements to struct inpcbinfo's definition:
(1) Add a locking guide for inpcbinfo.
(2) Annotate inpcbinfo fields with synchronisation information; not all
    annotations are 100% satisfactory.
(3) Reorder inpcbinfo fields so that the lock is at the head of the
    structure, and close to fields it protects.
(4) Sort fields that will eventually be hashlock/pcbgroup-related together
    even though they remain locked by ipi_lock for now.

Rewrite atomic operations for powerpc in order to achieve the following:
- Produce a type-clean implementation (in terms of functions arguments
  and returned values) for the primitives.
- Fix errors with _long() atomics where they ended up with the wrong
  arguments to be accepted.
- Follow the sys/type.h specifics that define the numbered types starting
  from standard C types.
- Let _ptr() version to not auto-magically cast arguments, but leave
  the burden on callers, as _ptr() atomic is intended to be used
  relatively rarely.

02003216e8 On amd64, change clang's default triple to 'x86_64-unknown-freebsd9.0',
similar to what we do for binutils.  When clang's default triple starts
with 'amd64-', it does not pass a proper -target-cpu option to its
first stage.

This can lead to problems, for example when structs are memcpy'd, and
clang erroneously assumes they are 16-byte aligned.  It will then use
the 'movaps' SSE instruction to implement the copy, which results in a
bus error if the struct is really 8-byte aligned.

I encountered this issue when gcc's /usr/libexec/cc1 started crashing
with SIGBUS, after rebuilding world with clang ToT, but it also affects
the version of clang that we have in the tree.  We were just lucky until
now, apparently. :)

694a586a43 Add a lock flags argument to the VFS_FHTOVP() file system
method, so that callers can indicate the minimum vnode
locking requirement. This will allow some file systems to choose
to return a LK_SHARED locked vnode when LK_SHARED is specified
for the flags argument. This patch only adds the flag. It
does not change any file system to use it and all callers
specify LK_EXCLUSIVE, so file system semantics are not changed.

342f1793ba 1. Prior to r214782, UMA did not support multipage allocations before
uma_startup2() was called.  Thus, setting the variable "booted" to true in
uma_startup() was ok on machines with UMA_MD_SMALL_ALLOC defined, because
any allocations made after uma_startup() but before uma_startup2() could be
satisfied by uma_small_alloc().  Now, however, some multipage allocations
are necessary before uma_startup2() just to allocate zone structures on
machines with a large number of processors.  Thus, a Boolean can no longer
effectively describe the state of the UMA allocator.  Instead, make "booted"
have three values to describe how far initialization has progressed.  This
allows multipage allocations to continue using startup_alloc() until
uma_startup2(), but single-page allocations may begin using
uma_small_alloc() after uma_startup().

2. With the aforementioned change, only a modest increase in boot pages is
necessary to boot UMA on a large number of processors.

3. Retire UMA_MD_SMALL_ALLOC_NEEDS_VM.  It has only been used between
r182028 and r204128.

This reflects failure to determine the pathname of the new directory in the
exit status (1). Normally, cd returns successfully if it did chdir() and the
call was successful.

In POSIX, -e only has meaning with -P; because our -L is not entirely
compliant and may fall back to -P mode, -e has some effect with -L as well.

7ba75dc4e9 Datasheet says vge(4) controllers support DAC but it seems that's
not true on old PCI based controllers.  DAC configuration is read
from EEPROM in device reset phase and driver can override DAC
configuration.  However I guess there is an undocumented reason why
EEPROM configuration does not enable DAC so do not blindly override
DAC configuration.  Recent PCIe based controllers are supposed to
support 64bit DMA so allow 64bit DMA only on PCIe based controllers.
