c53a28102a Fix ntfs such that it understand media with a non-512-bytes sector size:
1. Fixups are always done on 512 byte chunks (in stead of sectors). This
is kind of stupid.
2. Conevrt between NTFS blocknumbers (the blocksize equals the media
sector size) and the bread() and getblk() blocknr (which are 512-byte
sized)

NB: this change should not affect ntfs for 512-byte sector sizes.

58a0206d63 Define struct pcpu_md as the only MD field of struct pcpu (pc_acpi_id
excluded, as it's used by MI code) and mode the sysctl variables from
pcpu_stats to pcpu_md.
Adjust all references accordingly.

While nearby, change the PCPU sysctl tree so that they match the CPU
device sysctl tree -- they are now children of a static node called
"machdep.cpu" and are named only with their cpu ID.

6e8021eae1 Install libulog in /lib.
Because several applications in /bin use libulog (or may use it in the
nearby future), it must not live inside /usr. It seems like we don't
need to add the copy from /usr/lib to ObsoleteFiles.inc, because it's
cleaned up during installation of libulog automatically.

4dbb79b42d Allocate the VHPT for each CPU in cpu_mp_start(), rather than
allocating MAXCPU VHPTs up-front. This allows us to max-out MAXCPU
without memory waste -- MAXCPU is now 32 for SMP kernels.

This change also eliminates the VHPT scaling based in the total
memory in the system. It's the workload that determines the best size
of the VHPT. The workload can be affected by the amount of memory,
but not necessarily. For example, there's no performance difference
between VHPT sizes of 256KB, 512KB and 1MB when building the LINT
kernel. This was observed with a system that has 8GB of memory.
By default the kernel will allocate a 1MB VHPT. The user can tune the
system with the "machdep.vhpt.log2size" tunable.

ca7520fe57 Change the behavior of setenv(), putenv() and unsetenv() to continue parsing
instead of returning an error if a corrupt (not a "name=value" string) entry
in the environ array is detected when (re)-building the internal
environment.  This should prevent applications or libraries from
experiencing issues arising from the expectation that these calls will
complete even with corrupt entries.  The behavior is now as it was prior to
7.0.

04b0c5bbfa Add a libutempter compatibility interface to libulog.
The ulog_login_pseudo(3) and ulog_logout_pseudo(3) interfaces provide a
functionality identical to what libutempter has to offer. Just transform
libutempter's calls into the before mentioned functions.

libutempter doesn't work with utmpx, so instead of fixing I thought the
easiest way would be to integrate this functionality. libutempter is
used by applications like xterm and the KDE libraries, so if I ever
change the underlying file format, these applications will keep working
automatically.

Also increase __FreeBSD_version to indicate the addition (as well as the
import of libulog).

6e47ca1bc5 restore setting of sin_len (was removed in 1.146 last february) as
it seems that now it is necessary for 'forward' to work outside lo0.
The bug (and fix) was reported on 8.0. This patch probably applies

4bc9493e7c Make `make cleanilinks' work in /sys/modules.
cleanilinks wasn't listed in <bsd.subdir.mk>. Instead of adding it to
/sys/modules/Makefile, we'd better just add it to <bsd.subdir.mk>
directly, so we don't need to change files like /sys/modules/sound/Makefile
as well. This means you can finally clean up all those dangling symlinks
created by individual module compilation at once.

dc65bcacb2 Let w(1) use utmpx.
We don't have UT_*SIZE anymore. One of the reasons for that is because
all strings are null terminated, there is no need for apps to copy
strings out of the utmpx structure. This means we can define W_DISP*SIZE
lengths for all columns.

While there, adjust the sizes a little. Steal some bytes from the
username column, while extending the hostname column quite a bit.

066f913a94 MFp4:
Introduce ATA_CAM kernel option, turning ata(4) controller drivers into
cam(4) interface modules. When enabled, this options deprecates all ata(4)
peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers
(ada, cd, ...) and interfaces to be natively used instead.

As side effect of this, ata(4) mode setting code was completely rewritten
to make controller API more strict and permit above change. While doing
this, SATA revision was separated from PATA mode. It allows DMA-incapable
SATA devices to operate and makes hw.ata.atapi_dma tunable work again.

Also allow ata(4) controller drivers (except some specific or broken ones)
to handle larger data transfers. Previous constraint of 64K was artificial
and is not really required by PCI ATA BM specification or hardware.

b911cea8ff Port who(1) to utmpx.
(Un)fortunately there is no standardized interface to switch between
utmp database files, so we must call ulog_setutxfile() here.

I'm also changing the column widths to magic numbers here. Display
layout should in this case not be derived from structure fields sizes.
Because I don't want struct utmpx ever to become too small, the fields
are too big to reserve all the space.

logwtmp() gets called with the raw strings that are written to disk. For

1. Find provider by name.
2. Find provider by guid.
3. Find provider by name and guid.

Where it should have been:

2. Find provider by guid.

42782e4717 Massively extend libulog:
- Just like struct utmp, store strings inside struct utmpx itself. This
  is needed to make things like pututxline() work.
- Add ut_id and ut_pid fields, even though they have little use in our
  implementation.
- It turns out our "reboot" wtmp entries indicate a system boot, so
  remove REBOOT_TIME
- Implement getutxline() and pututxline
- Add getutxuser() and setutxfile(), which allows us to crawl wtmp and
  lastlog files as well.
- Add _ULOG_POSIX_NAMES, so we can already use the POSIX names if we
  really want to.

6468cb2ce0 Fix deadlock when ZVOLs are present and we are replacing dead component or
calling scrub when pool is in a degraded state. It will try to taste ZVOLs,
which will lead to deadlock, as ZVOL will try to acquire the same locks as
replace/scrub is holding already.

We can't simply skip provider based on their GEOM class, because ZVOL can have
providers build on top of it and we need to skip those as well.

We do it by asking for ZFS::iszvol attribute. Any ZVOL-based provider will give
us positive answer and we have to skip those providers.

This way we remove possibility to create ZFS pools on top of ZVOLs, but it is
not very useful anyway.

I believe deadlock is still possible in some very complex situations like when
we have MD provider on top of UFS file on top of ZVOL. When we try to replace
dead component in the pool mentioned ZVOL is based on, there might be a
deadlock when ZFS will try to taste MD provider. There is no easy way to detect
that, but it isn't very common.

ff09f97fb4 Do not ignore device interrupt if bus mastering is still active. It is
normal in case of media read error and some ATAPI cases, when transfer size
is unknown beforehand. PCI ATA BM specification tells that in case of such
underrun driver should just manually stop DMA engine. DMA engine should
same time guarantie that all bus mastering transfers completed at the moment
of driver reads interrupt flag asserted.
This change should fix interrupt storms and command timeouts in many cases.
