- Remove the eintrcnt/eintrnames usage and introduce the concept of sintrcnt/sintrnames which are symbols containing the size of the 2 tables. - For amd64/i386 remove the storage of intr* stuff from assembly files. This area can be widely improved by applying the same to other architectures and likely finding an unified approach among them and move the whole code to be MI. More work in this area is expected to happen fairly soon.

Implement a facility for dynamic per-cpu variables. - Modules and kernel code alike may use DPCPU_DEFINE(), DPCPU_GET(), DPCPU_SET(), etc. akin to the statically defined PCPU_*. Requires only one extra instruction more than PCPU_* and is virtually the same as __thread for builtin and much faster for shared objects. DPCPU variables can be initialized when defined. - Modules are supported by relocating the module's per-cpu linker set over space reserved in the kernel. Modules may fail to load if there is insufficient space available. - Track space available for modules with a one-off extent allocator. Free may block for memory to allocate space for an extent.

Pass the previously returned IRQ back to arm_get_next_irq() so that the implementation can guarantee forward progress in the event of a stuck interrupt or interrupt storm. This is especially critical for fast interrupt handlers, as they can cause a hard hang in that case. When first called, arm_get_next_irq() is passed -1.

Now that all platforms use genclock, shuffle things around slightly for better structure.
Much of this is related to <sys/clock.h>, which should really have been called <sys/calendar.h>, but unless and until we need the name, the repocopy can wait.
In general the kernel does not know about minutes, hours, days, timezones, daylight savings time, leap-years and such. All that is theoretically a matter for userland only.
Parts of kernel code does however care: badly designed filesystems store timestamps in local time and RTC chips almost universally track time in a YY-MM-DD HH:MM:SS format, and sometimes in local timezone instead of UTC. For this we have <sys/clock.h>
<sys/time.h> on the other hand, deals with time_t, timeval, timespec and so on. These know only seconds and fractions thereof.
Move inittodr() and resettodr() prototypes to <sys/time.h>. Retain the names as it is one of the few surviving PDP/VAX references.
Move startrtclock() to <machine/clock.h> on relevant platforms, it is a MD call between machdep.c/clock.c. Remove references to it elsewhere.
Remove a lot of unnecessary <sys/clock.h> includes.
Move the machdep.disable_rtc_set sysctl to subr_rtc.c where it belongs. XXX: should be kern.disable_rtc_set really, it's not MD.

Fix for the panic("vm_thread_new: kstack allocation failed") and silent NULL pointer dereference in the i386 and sparc64 pmap_pinit() when the kmem_alloc_nofault() failed to allocate address space. Both functions now return error instead of panicing or dereferencing NULL.
As consequence, vmspace_exec() and vmspace_unshare() returns the errno int. struct vmspace arg was added to vm_forkproc() to avoid dealing with failed allocation when most of the fork1() job is already done.
The kernel stack for the thread is now set up in the thread_alloc(), that itself may return NULL. Also, allocation of the first process thread is performed in the fork1() to properly deal with stack allocation failure. proc_linkup() is separated into proc_linkup() called from fork1(), and proc_linkup0(), that is used to set up the kernel process (was known as swapper).

Don't expose the uart_ops structure directly, but instead have it obtained through the uart_class structure. This allows us to declare the uart_class structure as weak and as such allows us to reference it even when it's not compiled-in. It also allows is to get the uart_ops structure by name, which makes it possible to implement the dt tag handling in uart_getenv(). The side-effect of all this is that we're using the uart_class structure more consistently which means that we now also have access to the size of the bus space block needed by the hardware when we map the bus space, eliminating any hardcoding.

Threading cleanup.. part 2 of several.
Make part of John Birrell's KSE patch permanent.. Specifically, remove: Any reference of the ksegrp structure. This feature was never fully utilised and made things overly complicated. All code in the scheduler that tried to make threaded programs fair to unthreaded programs. Libpthread processes will already do this to some extent and libthr processes already disable it.
Also: Since this makes such a big change to the scheduler(s), take the opportunity to rename some structures and elements that had to be moved anyhow. This makes the code a lot more readable.
The ULE scheduler compiles again but I have no idea if it works.
The 4bsd scheduler still reqires a little cleaning and some functions that now do ALMOST nothing will go away, but I thought I'd do that as a separate commit.

Rewrite ARM_USE_SMALL_ALLOC so that instead of the current behavior, it maps whole the physical memory, cached, using 1MB section mappings. This reduces the address space available for user processes a bit, but given the amount of memory a typical arm machine has, it is not (yet) a big issue. It then provides a uma_small_alloc() that works as it does for architectures which have a direct mapping.

Tweak how the MD code calls the fooclock() methods some. Instead of passing a pointer to an opaque clockframe structure and requiring the MD code to supply CLKF_FOO() macros to extract needed values out of the opaque structure, just pass the needed values directly. In practice this means passing the pair (usermode, pc) to hardclock() and profclock() and passing the boolean (usermode) to hardclock_cpu() and hardclock_process(). Other details: - Axe clockframe and CLKF_FOO() macros on all architectures. Basically, all the archs were taking a trapframe and converting it into a clockframe one way or another. Now they can just extract the PC and usermode values directly out of the trapframe and pass it to fooclock(). - Renamed hardclock_process() to hardclock_cpu() as the latter is more accurate. - On Alpha, we now run profclock() at hz (profhz == hz) rather than at the slower stathz. - On Alpha, for the TurboLaser machines that don't have an 8254 timecounter, call hardclock() directly. This removes an extra conditional check from every clock interrupt on Alpha on the BSP. There is probably room for even further pruning here by changing Alpha to use the simplified timecounter we use on x86 with the lapic timer since we don't get interrupts from the 8254 on Alpha anyway. - On x86, clkintr() shouldn't ever be called now unless using_lapic_timer is false, so add a KASSERT() to that affect and remove a condition to slightly optimize the non-lapic case. - Change prototypeof arm_handler_execute() so that it's first arg is a trapframe pointer rather than a void pointer for clarity. - Use KCOUNT macro in profclock() to lookup the kernel profiling bucket.

Refactor a bunch of scheduler code to give basically the same behaviour but with slightly cleaned up interfaces.
The KSE structure has become the same as the "per thread scheduler private data" structure. In order to not make the diffs too great one is #defined as the other at this time.
The KSE (or td_sched) structure is now allocated per thread and has no allocation code of its own.
Concurrency for a KSEGRP is now kept track of via a simple pair of counters rather than using KSE structures as tokens.
Since the KSE structure is different in each scheduler, kern_switch.c is now included at the end of each scheduler. Nothing outside the scheduler knows the contents of the KSE (aka td_sched) structure.
The fields in the ksegrp structure that are to do with the scheduler's queueing mechanisms are now moved to the kg_sched structure. (per ksegrp scheduler private data structure). In other words how the scheduler queues and keeps track of threads is no-one's business except the scheduler's. This should allow people to write experimental schedulers with completely different internal structuring.
A scheduler call sched_set_concurrency(kg, N) has been added that notifies teh scheduler that no more than N threads from that ksegrp should be allowed to be on concurrently scheduled. This is also used to enforce 'fainess' at this time so that a ksegrp with 10000 threads can not swamp a the run queue and force out a process with 1 thread, since the current code will not set the concurrency above NCPU, and both schedulers will not allow more than that many onto the system run queue at a time. Each scheduler should eventualy develop their own methods to do this now that they are effectively separated.
Rejig libthr's kernel interface to follow the same code paths as linkse for scope system threads. This has slightly hurt libthr's performance but I will work to recover as much of it as I can.
Thread exit code has been cleaned up greatly. exit and exec code now transitions a process back to 'standard non-threaded mode' before taking the next step. Reviewed by: scottl, peter MFC after: 1 week
