50eba76e30 kern: Add phashinit_flags(), which allows malloc(M_NOWAIT)
It will be used for the upcoming LRO hash table initialization.
And probably will be useful in other cases, when M_WAITOK can't
be used.

c71e075efb Revert bus_get_cpus() for now.
I really thought I had run this through the tinderbox before committing,
but many places need <sys/types.h> -> <sys/param.h> for <sys/bus.h> now.

2da46e01a0 Add a new bus method to fetch device-specific CPU sets.
bus_get_cpus() returns a specified set of CPUs for a device.  It accepts
an enum for the second parameter that indicates the type of cpuset to
request.  Currently two valus are supported:

 - LOCAL_CPUS (on x86 this returns all the CPUs in the package closest to
   the device when DEVICE_NUMA is enabled)
 - INTR_CPUS (like LOCAL_CPUS but only returns 1 SMT thread for each core)

For systems that do not support NUMA (or if it is not enabled in the kernel
config), LOCAL_CPUS fails with EINVAL.  INTR_CPUS is mapped to 'all_cpus'
by default.  The idea is that INTR_CPUS should always return a valid set.

Device drivers which want to use per-CPU interrupts should start using
INTR_CPUS instead of simply assigning interrupts to all available CPUs.
In the future we may wish to add tunables to control the policy of
INTR_CPUS (e.g. should it be local-only or global, should it ignore
SMT threads or not).

The x86 nexus driver exposes the internal set of interrupt CPUs from the
the x86 interrupt code via INTR_CPUS.

The ACPI bus driver and PCI bridge drivers use _PXM to return a suitable
LOCAL_CPUS set when _PXM exists and DEVICE_NUMA is enabled.  They also and
the global INTR_CPUS set from the nexus driver with the per-domain set from
_PXM to generate a local INTR_CPUS set for child devices.

973e983535 osd(9): Change array pointer to array pointer type from void*
This is a minor follow-up to r297422, prompted by a Coverity warning.  (It's
not a real defect, just a code smell.)  OSD slot array reservations are an
array of pointers (void **) but were cast to void* and back unnecessarily.
Keep the correct type from reservation to use.

osd.9 is updated to match, along with a few trivial igor fixes.

731f354016 Cause an error during 'make install' if trying to compile with CC.
This is limited to src-tree builds, meaning not extended to ports or other
out-of-tree builds.

This will help ensure that read-only OBJDIRS will be respected at install-time
by causing a more consistent failure for those who don't use a read-only
OBJDIR.  It also will cause Jenkins to yell.  This is a better solution than
trying to see CC=false as has been attempted and discussed before.

Of course this is only relevant for files generated by CC.

Disable this for META_MODE since it will detect the CFLAGS/command
change and force a rebuild.

ac91580f54 Add DEBUG_FLAGS to PROG_VARS and STRIP to PROG_OVERRIDE_VARS
This will allow the variables [*] to be overridden on a per-PROG basis,
which is useful when controlling "stripping" behavior for some tests
that require debug symbols or to be unstripped

DEBUG_FLAGS (similar to CFLAGS) supports appending, whereas STRIP is
an override

*: Due to how STRIP is defined in bsd.own.mk (in addition to
bsd.lib.mk and bsd.prog.mk), and the fact that bsd.test.mk pulls in
bsd.own.mk first, overriding STRIP doesn't work today.

A follow up commit is pending to "rectify" this after additional
testing is done.
