mrg | partly prepare for more than 2-level CPU speed scheduler support
put the calls behind looking at SPCF_IDLE and SPCF_1STCLASS mostly
behind functions that can grow support for more than 2 CPU classes.
4 new functions, with 2 of them just simple aliases for the 1st:
bool cpu_is_type(struct cpu_info *ci, int wanted);
bool cpu_is_idle_1stclass(struct cpu_info *ci)
bool cpu_is_1stclass(struct cpu_info *ci)
bool cpu_is_better(struct cpu_info *ci1, struct cpu_info *ci2);
with this in place, we can retain the desire to run on 1st-class by
preference, while also expanding cpu_is_better() to handle multiple
non 1st-class CPUs. ultimately, i envision seeing a priority number
where we can mark the fastest turbo-speed cores ahead of others, for
the case we can detect this.
XXX: use struct schedstate_percpu instead of cpu_info?
NFCI.

needs to go to the back of the run queue so round-robin actually happens,

ad | - Many small tweaks to the SMT awareness in the scheduler. It does a much
better job now at keeping all physical CPUs busy, while using the extra
threads to help out. In particular, during preempt() if we're using SMT,
try to find a better CPU to run on and teleport curlwp there.
- Change the CPU topology stuff so it can work on asymmetric systems. This
mainly entails rearranging one of the CPU lists so it makes sense in all
configurations.
- Add a parameter to cpu_topology_set() to note that a CPU is "slow", for
where there are fast CPUs and slow CPUs, like with the Rockwell RK3399.
Extend the SMT awareness to try and handle that situation too (keep fast
CPUs busy, use slow CPUs as helpers).

- sched_tick: cpu_need_resched is no longer the correct thing to do here.
All we need to do is OR the request into the local ci_want_resched.
- sched_resched_cpu: we need to set RESCHED_UPREEMPT even on softint LWPs,
especially in the !__HAVE_FAST_SOFTINTS case, because the LWP with the
LP_INTR flag could be running via softint_overlay() - i.e. it has been
temporarily borrowed from a user process, and it needs to notice the
resched after it has stopped running softints.

riastradh | Rename min/max -> uimin/uimax for better honesty.
These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.
HOWEVER! Some subsystems have
#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))
even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.
To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.
I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:
cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))
It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.
Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

maxv | Remove the kernel PMC code. Sent yesterday on tech-kern@.
This change:
* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.
* Removes the PMC code of ARM XSCALE.
* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.
* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.
* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.
* Removes the pmc_evid_t and pmc_ctr_t types.
* Removes all the associated man pages. The sets are marked as obsolete.

sleep dynamically.

rmind | Import of SCHED_M2 - the implementation of new scheduler, which is based
on the original approach of SVR4 with some inspirations about balancing
and migration from Solaris. It implements per-CPU runqueues, provides a
real-time (RT) and time-sharing (TS) queues, ready to support a POSIX
real-time extensions, and also prepared for the support of CPU affinity.
The following lines in the kernel config enables the SCHED_M2:
no options SCHED_4BSD
options SCHED_M2
The scheduler seems to be stable. Further work will come soon.

ad | - Fix interactivity problems under high load. Beacuse soft interrupts
are being stacked on top of regular LWPs, more often than not aston()
was being called on a soft interrupt thread instead of a user thread,
meaning that preemption was not happening on EOI.
- Don't use bool in a couple of data structures. Sub-word writes are not
always atomic and may clobber other fields in the containing word.
- For SCHED_4BSD, make p_estcpu per thread (l_estcpu). Rework how the
dynamic priority level is calculated - it's much better behaved now.
- Kill the l_usrpri/l_priority split now that priorities are no longer
directly assigned by tsleep(). There are three fields describing LWP
priority:
l_priority: Dynamic priority calculated by the scheduler.
This does not change for kernel/realtime threads,
and always stays within the correct band. Eg for
timeshared LWPs it never moves out of the user
priority range. This is basically what l_usrpri
was before.
l_inheritedprio: Lent to the LWP due to priority inheritance
(turnstiles).
l_kpriority: A boolean value set true the first time an LWP
sleeps within the kernel. This indicates that the LWP
should get a priority boost as compensation for blocking.
lwp_eprio() now does the equivalent of sched_kpri() if
the flag is set. The flag is cleared in userret().
- Keep track of scheduling class (OTHER, FIFO, RR) in struct lwp, and use
this to make decisions in a few places where we previously tested for a
kernel thread.
- Partially fix itimers and usr/sys/intr time accounting in the presence
of software interrupts.
- Use kthread_create() to create idle LWPs. Move priority definitions
from the various modules into sys/param.h.

ad | - Add a generic cross-call facility. Right now this only does threaded cross

up as bound kthreads (and not soft interrupts or something else) so that
the called functions can use the spl framework or disable preemption in
order to guarantee exclusive access to CPU-local data.

still execute on offline CPUs. As a result schedstate_percpu's::spc_flags

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

Revert rev1.26. l_estcpu is increased by only one cpu, not all of them.
