Merge r307360 from stable/9:
Incorporate a change from OpenBSD by millert@OpenBSD.org
Don't warn about valid time zone abbreviations. POSIX
through 2000 says that an abbreviation cannot start with ':', and
cannot contain ',', '-', '+', NUL, or a digit. POSIX from 2001
on changes this rule to say that an abbreviation can contain only
'-', '+', and alphanumeric characters from the portable character
set in the current locale. To be portable to both sets of rules,
an abbreviation must therefore use only ASCII letters." Adapted
from tzcode2015f.

MFC: r227006, r227281, r227282
Add a PCI front-end to esp(4) allowing it to support AMD Am53C974 and
replace amd(4) with the former in the amd64, i386 and pc98 GENERIC kernel
configuration files. Besides duplicating functionality, amd(4), which
previously also supported the AMD Am53C974, unlike esp(4) is no longer
maintained and has accumulated enough bit rot over time to always cause
a panic during boot as long as at least one target is attached to it
(see PR 124667).

With retirement of cpumask_t and usage of cpuset_t for representing a
mask of CPUs, pc_other_cpus and pc_cpumask become highly inefficient.
Remove them and replace their usage with custom pc_cpuid magic (as,
atm, pc_cpumask can be easilly represented by (1 << pc_cpuid) and
pc_other_cpus by (all_cpus & ~(1 << pc_cpuid))).
This change is not targeted for MFC because of struct pcpu members
removal and dependency by cpumask_t retirement.

etire the cpumask_t type and replace it with cpuset_t usage.
This is intended to fix the bug where cpu mask objects are
capped to 32. MAXCPU, then, can now arbitrarely bumped to whatever
value. Anyway, as long as several structures in the kernel are
statically allocated and sized as MAXCPU, it is suggested to keep it
as low as possible for the time being.
Technical notes on this commit itself:
- More functions to handle with cpuset_t objects are introduced.
The most notable are cpusetobj_ffs() (which calculates a ffs(3)
for a cpuset_t object), cpusetobj_strprint() (which prepares a string
representing a cpuset_t object) and cpusetobj_strscan() (which
creates a valid cpuset_t starting from a string representation).
- pc_cpumask and pc_other_cpus are target to be removed soon.
With the moving from cpumask_t to cpuset_t they are now inefficient
and not really useful. Anyway, for the time being, please note that
access to pcpu datas is protected by sched_pin() in order to avoid
migrating the CPU while reading more than one (possible) word
- Please note that size of cpuset_t objects may differ between kernel
and userland. While this is not directly related to the patch itself,
it is good to understand that concept and possibly use the patch
as a reference on how to deal with cpuset_t objects in userland, when
accessing kernland members.
- KTR_CPUMASK is changed and now is represented through a string, to be
set as the example reported in NOTES.
Please additively note that no MAXCPU is bumped in this patch, but
private testing has been done until to MAXCPU=128 on a real 8x8x2(htt)
machine (amd64).
Please note that the FreeBSD version is not yet bumped because of
the upcoming pcpu changes. However, note that this patch is not
targeted for MFC.
People to thank for the time spent on this patch:
- sbruno, pluknet and Nicholas Esborn (nick AT desert DOT net) tested
several revision of the patches and really helped in improving
stability of this work.
- marius fixed several bugs in the sparc64 implementation and reviewed
patches related to ktr.
- jeff and jhb discussed the basic approach followed.
- kib and marcel made targeted review on some specific part of the
patch.
- marius, art, nwhitehorn and andreast reviewed MD specific part of
the patch.
- marius, andreast, gonzo, nwhitehorn and jceel tested MD specific
implementations of the patch.
- Other people have made contributions on other patches that have been
already committed and have been listed separately.
Companies that should be mentioned for having participated at several
degrees:
- Yahoo! for having offered the machines used for testing on big
count of CPUs.
- The FreeBSD Foundation for having sponsored my devsummit attendance,
which has been instrumental.
- Sandvine for having offered offices and infrastructure during
development.
(I really hope I didn't forget anyone, if it happened I apologize in
advance).

Sync code with tzcode2010m
asctime.c:
* Set errno to EINVAL and return "??? ??? ?? ??:??:?? ????\n" if
asctime_r is called with a NULL struct tm pointer. (Note that
asctime_r is called by ctime_r and asctime; asctime is called by
ctime.)
localtime.c:
* Set errno to EINVAL and return WRONG if time1 is called with a
NULL struct tm pointer; avoid dereference if a NULL struct tm
pointer is passed to timelocal, timegm, or timeoff. (Note that
time1 is called by mktime, timegm, and timeoff; mktime is called
by timelocal.)
* more core-avoidance work
* Change to set timezone and altzone based on time types with
greatest transition times (for the benefit of Asia/Seoul).
zic.8:
* Warning about case-sensitivity of names, but not of abbrevations
zic.c:
* Conditionally output extra types with most-recently-use offsets
last (for use by systems with pre-2011 versions of localtime.c,
helping to ensure that globals "altzone and "timezone" get set
correctly).
The code has been running for nearly four weeks on my laptop running
FreeBSD 8.1 without a problem.

Merger of the quota64 project into head.
This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).
By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:
options QUOTA # Enable FFS quotas
If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.
There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.
Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.
