- 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."
ZFS file system was ported from OpenSolaris operating system. The code in under
CDDL license.
I'd like to thank all SUN developers that created this great piece of software.

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.

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

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()
