   enable workq interrupts on all cores.

50ffd2d643 regression/date: unset all LC_xxx vars and set LANG/LC_ALL
When running with a custom locale setup, it's easy to confuse the
date regression tests and cause them to fail, e.g. when LANG='C'
but LC_ALL='el_GR.UTF-8'.  Set LC_ALL to 'C', which overrides all
other LC_xxx options, to avoid this sort of problem.

62779d80fb Add missing __dead2 to __assert().
__assert() is called when an assertion fails. After printing an error
message, it will call abort(). abort() never returns, hence it has the
__dead2 attribute. Also add this attribute to __assert().

4b45b49a70 sh: Remove special %builtin PATH entry.
All builtins are now always found before a PATH search.

Most ash derivatives have an undocumented feature where the presence of an
entry "%builtin" in $PATH will cause builtins to be checked at that point of
the PATH search, rather than before looking at any directories as documented
in the man page (very old versions do document this feature).

I am removing this feature from sh, as it complicates the code, may violate
expectations (for example, /usr/bin/alias is very close to a forkbomb with
PATH=/usr/bin:%builtin, only /usr/bin/builtin not being another link saves
it) and appears to be unused (all the %builtin google code search finds is
in some sort of ash source code).

Note that aliases and functions took and take precedence above builtins.
Because aliases work on a lexical level they can only ever be overridden on
a lexical level (quoting or preceding 'builtin' or 'command'). Allowing
override of functions via PATH does not really fit in the model of sh and it
would work differently from %builtin if implemented.

Note: POSIX says special builtins are found before functions. We comply to
this because we do not allow functions with the same name as a special
builtin.

da2fcff746 Implement the __pthread_map_stacks_exec() for libthr.
Stack creation code is changed to call _rtld_get_stack_prot() to get
the stack protection right. There is a race where thread is created
during dlopen() of dso that requires executable stacks. Then,
_rtld_get_stack_prot() may return PROT_READ | PROT_WRITE, but thread
is still not linked into the thread list. In this case, the callback
misses the thread stack, and rechecks the required protection
afterward.

f9266eb1f9 Modify readdirplus in the experimental NFS server in a
manner analogous to r216633 for the regular server. This
change busies the file system so that VFS_VGET() is
guaranteed to be using the correct mount point even
during a forced dismount attempt. Since nfsd_fhtovp() is
not called immediately before readdirplus, the patch is
actually a clone of pjd@'s nfs_serv.c.4.patch instead of
the one committed in r216633.

a67b22d67f Change some variables from int to size_t. This is more accurate since
these variables represent sizes in one capacity or another.  There is
no reason to allow negative numbers.  Change userspace shared structure
elements that get used for the modified functions from int to uint32_t,
since it's not clear what userspace programs use these fields, and we
do not want to break binary compatibility.  This fixes a panic when
corrupt or bogus data is passed into the kernel.

of p_flags of PT_GNU_STACK phdr, but current stack protection does not
permit execution, the __pthread_map_stacks_exec symbol is looked up
and called. It should be implemented in libc or threading library and
change the protection mode of all thread stacks to be executable.

d942996baf On 32 bit architectures define (u)int64_t as (unsigned) long long instead
of (unsigned) int __attribute__((__mode__(__DI__))). This aligns better
with macros such as (U)INT64_C, (U)INT64_MAX, etc. which assume (u)int64_t
has type (unsigned) long long.

The mode attribute was used because long long wasn't standardised until
C99. Nowadays compilers should support long long and use of the mode
attribute is discouraged according to GCC Internals documentation.

The type definition has to be marked with __extension__ to support
compilation with "-std=c89 -pedantic".

9858863cd4 Fix types of some values in machine/_limits.h.
On some architectures UCHAR_MAX and USHRT_MAX had type unsigned int.
However, lacking integer suffixes for types smaller than int, their type
should correspond to that of an object of type unsigned char (or short)
when used in an expression with objects of type int. In that case unsigned
char (short) are promoted to int (i.e. signed) so the type of UCHAR_MAX and
USHRT_MAX should also be int.

Where MIN/MAX constants implicitly have the correct type the suffix has
been removed.

While here, correct some comments.

method.

When not creating a backup file, sed already renamed the changed copy onto
