be special-cased for just the root filesystem, but with this change
is now available for all UFS filesystems. This change is needed for

2a29286835 Fix the definition for PCPU_NAME_LEN, which is intended to fit
("CPU %d", cpuid) where cpuid <= MAXCPU.

1. sizeof(__XSTRING(MAXCPU) + 1) is a typo: typeof(__XSTRING(...) + 1)
   is 'char *', so sizeof() will return the size of the pointer, not
   the size of the string contents. The proper expression should be
   'sizeof(__XSTRING(MAXCPU)) + 1'.

2. One should not add one, but substract it: sizeof() accounts for the
   trailing '\0' and we have two sizeof's, so the size of one '\0'
   should be substracted -- this will give the maximal string buffer
   length for CPU with its number, no less, no more.

6fbe7bf4f2 Some refactoring for easier maintenance of the code. This is a follow-up
to re-establishment of 64bit arithmetic, but is committed separately, to
not obscure that conversion. This commit does not change the observed
behaviour of expr in any way. Style will be fixed in a follow-up commit.

fa717604a4 Make /bin/expr support 64bit numeric range and range checks by default,
again. This brings back the behaviour of expr in FreeBSD-4, which had been
reverted due to an assumed incompatbility with POSIX.1 for FreeBSD-5.

This issue has been discussed in the freebsd-standards list, and the
consensus was, that POSIX.1 is in fact not violated by this extension,
since it affects only cases of POSIX undefined behaviour (overflow of
signed long).

Other operating systems did upgrade their versions of expr to support
64bit range, after it had been initially brought to FreeBSD. They have
used it for a decade without problems, meanwhile.

The -e option is retained, but it will only select less strict checking
of numeric parameters (leading white-space, leading "+" are allowed and
skipped, an empty string is considered to represent 0 in numeric context.)
The call of check_utility_compat() as a means of establishing backwards
compatibility with FreeBSD-4 is considered obsolete, but preserved in
this commit. It is expected to be removed in a later revision of this
file.

0eb8c1410a Implement basic support for memory attributes. At this time we only
distinguish between UC and WB memory so that we can map the page to
either a region 6 address (for UC) or a region 7 address (for WB).

This change is only now possible, because previously we would map
regions 6 and 7 with 256MB translations and on top of that had the
kernel mapped in region 7 using a wired translation. The introduction
of the PBVM moved the kernel into its own region and freed up region
7 and allowed us to revert to standard page-sized translations.

This commit inroduces pmap_page_to_va() that respects the attribute.

5604e481b1 Fix the "passability" test in fdcopy().
Rather than checking to see if a descriptor is a kqueue, check to see if
its fileops flags include DFLAG_PASSABLE.

At the moment, these two tests are equivalent, but this will change with
the addition of capabilities that wrap kqueues but are themselves of type
DTYPE_CAPABILITY. We already have the DFLAG_PASSABLE abstraction, so let's
use it.

This change has been tested with [the newly improved] tools/regression/kqueue.

345f2b96e2 Clarify the meaning of a test.
Rather than using err() if either of two failure conditions
fires (which can produce spurious error messages), just use
errx() if the one condition that really matters fires.

In practice, this single test is enough to detect the failure
mode we're looking for (kqueue being inherited across fork).

0136244a52 Ensure that kqueue is not inherited across fork().
Modify the existing unit test (from libkqueue) which already exercises process events via
fork() and kill(). Now, the child process simply checks that the 'kqfd' descriptor is invalid.

Some minor modifications were required to make err() work correctly. It seems that this test
was imported using the output of a configure script, but config.h was not included in key
places, nor was its syntax correct (need '#define HAVE_FOO 1' rather than '#define HAVE_FOO').

Finally, change main() to run the "proc" suite by default, but widened the '#if TODO' in
proc.c to include the non-functioning test event_trigger().
