- Westmere based CPU (Xeon 5600, Corei7 980X) support.
- New man pages with events list for core and uncore.
- Updated Corei7 events with Intel 253669-033US December 2009 doc.
There is some removed events in the documentation, they have been
kept in the code but documented in the man page as obsolete.
- Offcore response events can be setup with rsp token.

shared and generalized between our current amd64, i386 and pc98.
This is just an initial step that should lead to a more complete effort.
For the moment, a very simple porting of cpufreq modules, BIOS calls and
the whole MD specific ISA bus part is added to the sub-tree but ideally
a lot of code might be added and more shared support should grow.

While currently there is only "/dev/full" [2], we are planning to see more

future should the list grow too long.
This is not part of linux.ko as also non-linux binaries like kFreeBSD
userland or ports can make use of this as well.

I really don't want any pieces of code to include ioctl_compat.h, so let
the ibcs2 and svr4 compat leave sgtty alone. If they want to support
sgtty, they should emulate it on top of termios, not sgtty.
The code has been marked with BURN_BRIDGES for a long time. ibcs2 and
svr4 are not really popular pieces of code anyway.

simplifies calls into ioctl() on network interfaces, especially
in the multicast code, as well as eliminates deferred invocation
of interface if_start routines.
Disable the build on device drivers still depending on
IFF_NEEDSGIANT as they no longer compile. They will be removed
in a few weeks if they haven't been made MPSAFE in that time.

When copying big structures, LLVM generates calls to memmove(), because
it may not be able to figure out whether structures overlap. This caused
linker errors to occur. memmove() is now implemented using bcopy().
Ideally it would be the other way around, but that can be solved in the
future. On ARM we don't do add anything, because it already has
memmove().

module; the ath module now brings in the hal support. Kernel
config files are almost backwards compatible; supplying
device ath_hal
gives you the same chip support that the binary hal did but you
must also include
options AH_SUPPORT_AR5416
to enable the extended format descriptors used by 11n parts.
It is now possible to control the chip support included in a
build by specifying exactly which chips are to be supported
in the config file; consult ath_hal(4) for information.
dependencies. A 'struct pmc_classdep' structure describes operations
on PMCs; 'struct pmc_mdep' contains one or more 'struct pmc_classdep'

Inside PMC class dependent code, row indices are relative to the
PMCs supported by the PMC class; MI code in "hwpmc_mod.c" translates
global row indices before invoking class dependent operations.

- Move TSC handling to file "hwpmc_tsc.c".

making the relevant files standard. This avoids duplication and
makes it easier to override/disable unwanted schemes. Since ARM
doesn't have a DEFAULTS configuration file, leave the source
files for the BSD and MBR partitioning schemes in files.arm for
now.
Implement all futex atomic operations in assembler to not depend on the
fuword() that does not allow to distinguish between -1 and failure return.
Correctly return 0 from atomic operations on success.

aches as a read-only file. In a number of cases this has led to
compiles failing- usually due to some strange NFS drift which thinks
that the opt_ah.h in the compile directory is out of date wrt the
source it is copied from. When the copy is executed again, it fails
because the target is read-only. Oops. Modify the compile hooks

dynamic nature (if no native aio code is available, the linux part
returns ENOSYS because of missing requisites) should be solved differently
than it is.
All this will be done in P4.
Not included in this commit is a backout of the changes to the native aio
code (removing static in some places). Those changes (and some more) will
also be needed when the reworked linux aio stuff will reenter the tree.

and pc98 MD files. Remove nodevice and nooption lines specific
to sio(4) from ia64, powerpc and sparc64 NOTES. There were no
such lines for arm yet.
sio(4) is usable on less than half the platforms, not counting
a future mips platform. Its presence in MI files is therefore
increasingly becoming a burden.
lnc(4) on PC98 and i386. The ISA front-end supports the same non-PNP
network cards as lnc(4) did and additionally a couple of PNP ones.
Like lnc(4), the C-bus front-end of le(4) only supports C-NET(98)S
and is untested due to lack of such hardware, but given that's it's
based on the respective lnc(4) and not too different from the ISA
front-end it should be highly likely to work.
- Remove the descriptions of le(4), which where converted from lnc(4),
from sys/i386/conf/NOTES and sys/pc98/conf/NOTES as there's a common
one in sys/conf/NOTES.
the linux module, since it is not cross-platform
- move linprocfs from "files" and "options" to architecture specific files,
since it only makes sense to build this for those architectures, where we
also have a linuxolator
- disable the build of the linuxolator on our tier-2 architecture "Alpha":
* we don't have a linux_base port which supports Alpha and at the
same time is not outdated/obsoleted upstream/in a good condition/
currently working
* the upcomming new default linux base port is based upon Fedora
Core 3 (security support via http://www.fedoralegacy.org), which
isn't available for Alpha (like the current default linux base
port which is based upon Red Hat 8)
* nobody answered my request for testing it ~1 month ago on
current@ and alpha@ (it doesn't surprises me, see above)
* a SoC student wouldn't have to waste time on something which
nobody is willing to test
This does not remove the alpha specific MD files of the linuxolator yet.

end for isa(4).
o Add a seperate bus frontend for acpi(4) and allow ISA DMA for
it when ISA is configured in the kernel. This allows acpi(4)
attachments in non-ISA configurations, as is possible for ia64.
o Add a seperate bus frontend for pci(4) and detect known single
port parallel cards.
o Merge PC98 specific changes under pc98/cbus into the MI driver.
The changes are minor enough for conditional compilation and
in this form invites better abstraction.
o Have ppc(4) usabled on all platforms, now that ISA specifics
are untangled enough.

With the most of modern SMB providers requiring encryption by

of NETSMB optional at the build time.
This will also return smbfs.ko to its former properties users
are rather accustomed to.
