592cd7d3be Don't advertise the "OS visible workarounds" feature in cpuid.80000001H:ECX.
bhyve doesn't emulate the MSRs needed to support this feature at this time.

Don't expose any model-specific RAS and performance monitoring features in
cpuid leaf 80000007H.

Emulate a few more MSRs for AMD: TSEG base address, TSEG address mask and
BIOS signature and P-state related MSRs.

This eliminates all the unimplemented MSRs accessed by Linux/x86_64 kernels
2.6.32, 3.10.0 and 3.17.0.

2688a818a3 Don't advertise the Instruction Based Sampling feature because it requires
emulating a large number of MSRs.

Ignore writes to a couple more AMD-specific MSRs and return 0 on read.

This further reduces the unimplemented MSRs accessed by a Linux guest on boot.

02904c45ab Hide extended PerfCtr MSRs on AMD processors by clearing bits 23, 24 and 28 in
CPUID.80000001H:ECX.

Handle accesses to PerfCtrX and PerfEvtSelX MSRs by ignoring writes and
returning 0 on reads.

This further reduces the number of unimplemented MSRs hit by a Linux guest
during boot.

5a1f0b36b1 Fix topology enumeration issues exposed by AMD Bulldozer Family 15h processor.
Initialize CPUID.80000008H:ECX[7:0] with the number of logical processors in
the package. This fixes a panic during early boot in NetBSD 7.0 BETA.

Clear the Topology Extension feature bit from CPUID.80000001H:ECX since we
don't emulate leaves 0x8000001D and 0x8000001E. This fixes a divide by zero
panic in early boot in Centos 6.4.

Tested on an "AMD Opteron 6320" courtesy of Ben Perrault.

56d8b96cbc Start removing the omap3 support. In base it was only ever a header and a
few changes to drivers, no kernel config was added. As the SoCs are quite
old and the code is unmaintained start the process of removing support by
deleting the header file and code that depends on it along with the macro
SOC_OMAP3. Other Ti SoCs shouldn't be affected, other than for us to have
less code to maintain.

d49c6f029c Add an AC line monitor so power_profile can work
Summary:
Add a polling loop (1Hz) to monitor the battery and AC status, to notify devd
like ACPI does for power monitoring.  This allows /etc/rc.d/power_profile to
work on PowerPC laptops

Test Plan:
Tested on a Titanium PowerBook, configuring economy_cpu_freq and
performance_cpu_freq, disabling powerd.

f0cace5d94 When deciding whether to call m_pullup() even though there is adequate
data in an mbuf, use M_WRITABLE() instead of a direct test of M_EXT;
the latter both unnecessarily exposes mbuf-allocator internals in the
protocol stack and is also insufficient to catch all cases of
non-writability.

(NB: m_pullup() does not actually guarantee that a writable mbuf is
returned, so further refinement of all of these code paths continues to
be required.)

ddbe5b951f Fix nits in previous commit:
1.  Remove initializer for badstack_sbuf_size; it gets set unconditionally.
2.  Remove meaningless comment.
3.  Group witness_count and its sysctl together.
4.  Fix spacing in for statements (space after for and within condition).
5.  Change *all* M_NOWAIT usages in witness_initialize() to M_WAITOK; not
    just those that were newly introduced -- the allocation is assumed to
    succeed for all allocations.
6.  Avoid using uint8_t as the base type in sizeof() expressions; Use the
    variable name (w_rmatrix) as much as possible.
