a3c8c2e60f Reduce the limit of vnodes on i386 when ZFS is loaded to 3/4 of the original
value, so we don't run out of KVA. The default vnodes limit fits better for
UFS, but ZFS allocated more file system specific memory for a vnode than UFS.

Don't touch vnodes limit if we detect it was tuned by system administrator
and restore original value when ZFS is unloaded.

This isn't final fix, but before we implement something better, this will
help to stabilize ZFS under heavy load on i386.

7f368082ad When checking the sequence number of a TCP header embedded in an
ICMP error message, do not access th_flags. The field is beyond
the first eight bytes of the header that are required to be present
and were pulled up in the mbuf.

A random value of th_flags can have TH_SYN set, which made the
sequence number comparison not apply the window scaling factor,
which led to legitimate ICMP(v6) packets getting blocked with
"BAD ICMP" debug log messages (if enabled with pfctl -xm), thus
breaking PMTU discovery.

Triggering the bug requires TCP window scaling to be enabled
(sysctl net.inet.tcp.rfc1323, enabled by default) on both end-
points of the TCP connection. Large scaling factors increase
the probability of triggering the bug.

f1172c58e5 Fix a bug where the callout might not be initialized before being used.
Rev 1.9 introduced another path where machclk_freq would be initialized
before the rest of setup was done (i.e. initializing the callout).  Make
the one-time initialization a separate function and make init_machclk()
able to be called multiple times, any time.  We depend on tsc_freq first
being updated from the highest priority eventhandler, thus we run last
and call init_machclk() to set machclk_freq.  Also, don't initialize
static variables to 0.

b166b92692 Reimplement traverse() helper function:
1. Pass locking flags to VFS_ROOT().
2. Check v_mountedhere while the vnode is locked.
3. Always return locked vnode on success.

Change 1 fixes problem reported by Stephen M. Rumble - after
zfs_vfsops.c,1.9 change, zfs_root() no longer locks the vnode
unconditionally and traverse() didn't pass right lock type to
VFS_ROOT(). The result was that kernel paniced when .zfs/ directory
was accessed via NFS.

171c4b21e2 - Always try to write one whole page at a time.
- vm_page_undirty() is enough (instead of vm_page_set_validclean()), but it has
  to be called before we write the data in case someone makes page dirty after
  our write, but before our vm_page_undirty() call.
- Always dmu_write, not matter if uiomove() succeeded, because it could
  partially be ok and we would lose some changes.

2d03e33170 Try to stabilize ZFS with regard to memory consumption:
- Allow to shrink ARC down to 16MB (instead of 64MB).
- Set arc_max to 1/2 of kmem_map by default.
- Start freeing things earlier when low memory situation is detected.
- Serialize execution of arc_lowmem().

I decided to setup minimum ZFS memory requirements to 512MB of RAM and 256MB of
kmem_map size. If there is less RAM or kmem_map, a warning will be printed.
World is cruel, be no better. In other words: modern file system requires
modern hardware:)

From ZFS administration guide:

"Currently the minimum amount of memory recommended to install a Solaris
 system is 512 Mbytes. However, for good ZFS performance, at least one
 Gbyte or more of memory is recommended."

0d4ac62a35 Add an interface for drivers to be notified of changes to CPU frequency.
cpufreq_pre_change is called before the change, giving each driver a chance
to revoke the change.  cpufreq_post_change provides the results of the
change (success or failure).  cpufreq_levels_changed gives the unit number
of the cpufreq device whose number of available levels has changed.  Hook
in all the drivers I could find that needed it.

* TSC: update TSC frequency value.  When the available levels change, take the
highest possible level and notify the timecounter set_cputicker() of that
freq.  This gets rid of the "calcru: runtime went backwards" messages.
* identcpu: updates the sysctl hw.clockrate value
* Profiling: if profiling is active when the clock changes, let the user
know the results may be inaccurate.

0f3ff68694 Version 0.9.20.3:
o remove os-specific glue code; it's now the responsibility of
  the driver
o add wackelf utility for patching the ELF magic number on arm
  builds since noone can agree on how to mark a .o file as not
  having any floating point instructions
o remove radar/dfs-related entry points; folks have finally
  decided how to support dfs w/o polluting the hal
o properly recognize AR2424 chips (they were being rejected on
  attach despite being fully supported)
o add HAL_CAP_RXORN_FATAL capability to control how RXORN errors
  are handled; previously RXORN was always treated as fatal because
  older chips required a reset; now we do not treat it as fatal
  for "newer chips" (noone seems to know what the cutoff is so
  this capability can be used to override the current guestimate)
o HAL_CAP_RXTSTAMP_PREC capability to export the number of bits
  of precision for timestamp data returned in the rx descriptor
o remove public exposure of the compression buffer; it is chip
  specific and never belonged in the public view
o change definition of HAL_INT_GLOBAL from an enum member to a
  #define to workaround compilers that bitch about enum values
  that appear overflow 31 bits
o add support for newer chips that can store the tkip mic key
  together with the cipher key in a single key cache entry
o split tx/rx descriptor into a h/w section and a s/w portion;
  this permits storing the s/w area in cached memory when the
  h/w area is stored in uncached memory; this also shrinks
  memory use since only one status block is needed while multiple
  tx/rx descriptors may be required per frame
o add final transmit series index to the transmit descriptor status
  so rate control algorithms don't need to grovel through h/w state
  to find it
o remove ds_vdata field from the descriptor state as part of the
  radar changes
o fix excessive stack usage for some 5212 rf backends
o correct rfkill handling when the pin polarity is 0 true
o correct handling of tsf wrap when reading 64-bit values

d94f2a68f8 Introduce a new entry point, mac_create_mbuf_from_firewall. This entry point
exists to allow the mandatory access control policy to properly initialize
mbufs generated by the firewall. An example where this might happen is keep
alive packets, or ICMP error packets in response to other packets.

This takes care of kernel panics associated with un-initialize mbuf labels
when the firewall generates packets.

[1] I modified this patch from it's original version, the initial patch
    introduced a number of entry points which were programmatically
    equivalent. So I introduced only one. Instead, we should leverage
    mac_create_mbuf_netlayer() which is used for similar situations,
    an example being icmp_error()

    This will minimize the impact associated with the MFC
