Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * The counters are accessed in one go using a 64-bit register.

- * Both counters are controlled using a single control register.  The
- * only way to stop all sampling is to clear all of the context (user,
- * supervisor, hypervisor) sampling enable bits.  But these bits apply
- * to both counters, thus the two counters can't be enabled/disabled
- * individually.
- *
- * The control register has two event fields, one for each of the two
- * counters.  It's thus nearly impossible to have one counter going
- * while keeping the other one stopped.  Therefore it is possible to
- * get overflow interrupts for counters not currently "in use" and
- * that condition must be checked in the overflow interrupt handler.
- *
- * So we use a hack, in that we program inactive counters with the
- * "sw_count0" and "sw_count1" events.  These count how many times
- * the instruction "sethi %hi(0xfc000), %g0" is executed.  It's an
- * unusual way to encode a NOP and therefore will not trigger in

- * which performs the flushw.
- *
- * The SMP TLB coherency scheme we use works as follows:
- *
- * 1) mm->cpu_vm_mask is a bit mask of which cpus an address
- *    space has (potentially) executed on, this is the heuristic
- *    we use to avoid doing cross calls.
- *
- *    Also, for flushing from kswapd and also for clones, we
- *    use cpu_vm_mask as the list of cpus to make run the TLB.
- *
- * 2) TLB context numbers are shared globally across all processors
- *    in the system, this allows us to play several games to avoid
- *    cross calls.
- *
- *    One invariant is that when a cpu switches to a process, and
- *    that processes tsk->active_mm->cpu_vm_mask does not have the
- *    current cpu's bit set, that tlb context is flushed locally.
- *
- *    If the address space is non-shared (ie. mm->count == 1) we avoid
- *    cross calls when we want to flush the currently running process's
- *    tlb state.  This is done by clearing all cpu bits except the current
- *    processor's in current->mm->cpu_vm_mask and performing the
- *    flush locally only.  This will force any subsequent cpus which run
- *    this task to flush the context from the local tlb if the process
- *    migrates to another cpu (again).
- *

-	 * As far as I can make out from the manual, the CEE trap is
-	 * only for correctable errors during memory read accesses by
-	 * the front-end of the processor.
-	 *
-	 * The code below is only for trap level 1 CEE events, as it
-	 * is the only situation where we can safely record and log.
-	 * For trap level >1 we just clear the CE bit in the AFSR and
-	 * return.
-	 *
-	 * This is just like __spiftire_access_error above, but it
-	 * specifically handles correctable errors.  If an
-	 * uncorrectable error is indicated in the AFSR we will branch
-	 * directly above to __spitfire_access_error to handle it
-	 * instead.  Uncorrectable therefore takes priority over
-	 * correctable, and the error logging C code will notice this
-	 * case by inspecting the trap type.

-/* Sample sun4m IRQ layout:
- *
- * 0x22 - Power
- * 0x24 - ESP SCSI
- * 0x26 - Lance ethernet
- * 0x2b - Floppy
- * 0x2c - Zilog uart
- * 0x32 - SBUS level 0
- * 0x33 - Parallel port, SBUS level 1
- * 0x35 - SBUS level 2
- * 0x37 - SBUS level 3
- * 0x39 - Audio, Graphics card, SBUS level 4
- * 0x3b - SBUS level 5
- * 0x3d - SBUS level 6
- *
- * Each interrupt source has a mask bit in the interrupt registers.
- * When the mask bit is set, this blocks interrupt deliver.  So you
- * clear the bit to enable the interrupt.
- *
- * Interrupts numbered less than 0x10 are software triggered interrupts
- * and unused by Linux.
- *
- * Interrupt level assignment on sun4m:
- *
- *	level		source
- * ------------------------------------------------------------
- *	  1		softint-1
- *	  2		softint-2, VME/SBUS level 1
- *	  3		softint-3, VME/SBUS level 2
- *	  4		softint-4, onboard SCSI
- *	  5		softint-5, VME/SBUS level 3
- *	  6		softint-6, onboard ETHERNET
- *	  7		softint-7, VME/SBUS level 4
- *	  8		softint-8, onboard VIDEO
- *	  9		softint-9, VME/SBUS level 5, Module Interrupt
- *	 10		softint-10, system counter/timer
- *	 11		softint-11, VME/SBUS level 6, Floppy
- *	 12		softint-12, Keyboard/Mouse, Serial
- *	 13		softint-13, VME/SBUS level 7, ISDN Audio
- *	 14		softint-14, per-processor counter/timer
- *	 15		softint-15, Asynchronous Errors (broadcast)
- *
- * Each interrupt source is masked distinctly in the sun4m interrupt
- * registers.  The PIL level alone is therefore ambiguous, since multiple
- * interrupt sources map to a single PIL.
- *
- * This ambiguity is resolved in the 'intr' property for device nodes
- * in the OF device tree.  Each 'intr' property entry is composed of
- * two 32-bit words.  The first word is the IRQ priority value, which
- * is what we're intersted in.  The second word is the IRQ vector, which
- * is unused.
- *
- * The low 4 bits of the IRQ priority indicate the PIL, and the upper
- * 4 bits indicate onboard vs. SBUS leveled vs. VME leveled.  0x20
- * means onboard, 0x30 means SBUS leveled, and 0x40 means VME leveled.
- *
- * For example, an 'intr' IRQ priority value of 0x24 is onboard SCSI
- * whereas a value of 0x33 is SBUS level 2.  Here are some sample
- * 'intr' property IRQ priority values from ss4, ss5, ss10, ss20, and
- * Tadpole S3 GX systems.
- *
- * esp:		0x24	onboard ESP SCSI
- * le:		0x26	onboard Lance ETHERNET
- * p9100:	0x32	SBUS level 1 P9100 video
- * bpp:		0x33	SBUS level 2 BPP parallel port device
- * DBRI:	0x39	SBUS level 5 DBRI ISDN audio
- * SUNW,leo:	0x39	SBUS level 5 LEO video
- * pcmcia:	0x3b	SBUS level 6 PCMCIA controller
- * uctrl:	0x3b	SBUS level 6 UCTRL device
- * modem:	0x3d	SBUS level 7 MODEM
- * zs:		0x2c	onboard keyboard/mouse/serial
- * floppy:	0x2b	onboard Floppy
- * power:	0x22	onboard power device (XXX unknown mask bit XXX)

-	 * XXX answer is yes.  We stick fork_kpsr in UREG_G0 and
-	 * XXX fork_kwim in UREG_G1 (global registers are considered
