Use slightly more idiomatic expression to get the address of array.

The ia32_get_mcontext() does not need to set PCB_FULL_IRET.

When handling an exception from the attempt from loading the faulting
context on return from the trap handler, re-enable the interrupts on
i386 and amd64.

Add amd64-specific ddb command 'show phys2dmap'.

Correct the type for the literal used on the left side of the shift up
to 63 bit positions.

Do not fill the save area and do not set the saved bit in the xstate
bit vector for the state which is not marked as enabled in xsave_mask.

remove some cvs workarounds.

The check to ensure that xstate_bv always has XFEATURE_ENABLED_X87 and
XFEATURE_ENABLED_SSE bits set is not needed.  CPU correctly handles
any bitmask which is subset of the enabled bits in %XCR0.

More, CPU instructions XSAVE and XSAVEOPT could write the mask without
e.g. XFEATURE_ENABLED_SSE, after the VZEROALL.  The check prevents the
restoration of the otherwise valid FPU save area.

Add a clts() wrapper around the 'clts' instruction to <machine/cpufunc.h>
on x86 and use that to implement stop_emulating() in the fpu/npx code.
Reimplement start_emulating() in the non-XEN case by using load_cr0() and
rcr0() instead of the 'lmsw' and 'smsw' instructions.  Intel explicitly
discourages the use of 'lmsw' and 'smsw' on 80386 and later processors in
the description of these instructions in Volume 2 of the ADM.

xsavem natively supported, get rid of assembly versions in code

Several fixes to the amd64 disassembler:
- Decode the 'xsave', 'xrstor', 'xsaveopt', 'xgetbv', 'xsetbv', and
  'rdtscp' instructions.
- Add generic support for opcodes that are escape bytes used for
  multi-byte opcodes (such as the 0x0f prefix).  Use this to replace
  the hard-coded 0x0f special case and add support for three-byte
  opcodes that use the 0x0f38 prefix.
- Decode all Intel VMX instructions.  invept and invvpid in particular are
  three-byte opcodes that use the 0x0f38 escape prefix.
- Rework how the special 'SDEP' size flag works such that the default
  instruction name (i_name) is the instruction when the data size
  prefix (0x66) is not specified, and the alternate name in i_extra is
  used when the prefix is included.
- Add a new 'ADEP' size flag similar to 'SDEP' except that it chooses
  between i_name and i_extra based on the address size prefix (0x67).
  Use this to fix the decoding for jrcxz vs jecxz which is determined
  by the address size prefix, not the operand size prefix.  Also, jcxz
  is not possible in 64-bit mode, but jrcxz is the default instruction
  for that opcode.
- Add support for handling instructions that have a mandatory 'rep'
  prefix (this means not outputting the 'repe ' prefix until determining
  if it is used as part of an opcode).  Make 'pause' less of a special
  case this way.
- Decode 'cmpxchg16b' and 'cdqe' which are variants of other instructions
  but with a REX.W prefix.

add descriptions for nics.

Real hardware, as opposed to QEMU, does not allow to have a call gate
in long mode which transfers control to 32bit code segment. Unbreak
the lcall $7,$0 implementation on amd64 by putting the 64bit user code
segment' selector into call gate, and execute the 64bit trampoline
which converts the return frame into 32bit format and switches back to
32bit mode for executing int $0x80 trampoline.

Refactor linux elf/note logic

Regenerate syscall table.

Add flag MPSAFE to sysctl leaf nodes so they don't require GIANT lock. More work is necesary to make things MPSAFE but this could allow for some serious performance benefits.

Opteron rev E family of processor expose a bug where, in very rare
ocassions, memory barriers semantic is not honoured by the hardware
itself. As a result, some random breakage can happen in uninvestigable
ways (for further explanation see at the content of the commit itself).

As long as just a specific familly is bugged of an entire architecture
is broken, a complete fix-up is impratical without harming to some
extents the other correct cases.
Considering that (and considering the frequency of the bug exposure)
just print out a warning message if the affected machine is identified.

Refactor the linux_mmap_common function to take individual arguments similar to FreeBSD.  This is easier to read and similar to other kernel interfaces.  This also makes it easier to fix the mmap offsets greater than 32  bits.   We can deal with a 64 bit file offset now.  This is based on a patch to FreeBSD by Christian Zander @ NVIDIA

Fix build error with missing header on amd64.

Update our cpu types and include a list of vendors of CPUs.  This will be used with identcpu and kernel modules later to "detect" cpu vendors to enable/disable features.

Add amd_pmifo flag to store advanced power management info with AMD cpus.

add cpu identification bits for several features including sse 4.1, 4.2, MOVBE, POPCNT, XSAVE and OSXSAVE

There are several new CPUIDs to recognize AMD Extended Features, ECX 07FFh for Phenom processor.

Add atheros wireless NICs

Add cpufreq(4) and GEOM_LABEL aka GLABEL to GENERIC on i386 and amd64.

cpufreq works with powerd which is already enabled on systems without ACPI support for CPU frequency using several chipsets (intel).  This may cause problems for some people which might require an install option for powerd.  This needs testing.

glabel allows one to name disks and reference them in dev by that name instead of their normal designation like acd0 or ad0s2d.  By adding this to generic, we can easily make a live cd that works on more types of CDROMs.  FreeBSD is also moving in this direction for other reasons.

Until the latter can be tested on sparc64, I'll keep it out of generic.  We don't support sun style labels right now anyway.

Syncronize the cpu detection code on i386 and amd64 with FreeBSD 6.2.

Add better SMP detection including multicore cpus.  Detect features on newer processors and initialize them properly.  Add support for some newer via c7 cpus.

Also make a subtle adjustment to tcp_syncache.c (unrelated)

SMP is now default on amd64.

Sync with FreeBSD 6.1 Release.

Throw out all the logical APIC ID stuff and just wire up the interrupts to individual CPUs using physical addressing and fixed delivery mode.

Change the x86 interrupt code to allocate IDT vectors on demand.

Apply some patches from FreeBSD 6.1 Release for cpu detection, ioctl fixes, etc.

Change i386 GENERIC kernel to include VESA and raster support so that end users can easily switch to 800x600 and other video modes in the console.  While the kernel size is larger, it makes more sense on a desktop.

FreeBSD-SA6:13 and 14 were patched.  The nis software and amd athlon fpu handling fixed.  Changes to echo and pfctl are needed to fix compile bugs with changes related to cvs tags and macros.

This commit was generated by cvs2svn to compensate for changes in r5, which
included commits to RCS files with non-trunk default branches.
