+ * is free-running, and can't generate interrupts.
+ *
+ * The 508 kHz timers are ideal for use for the timer interrupt, as the
+ * most common values of HZ divide 508 kHz nicely. We pick one of the 16
+ * bit timers (timer 1) since we don't need more than 16 bits of reload
+ * value as long as HZ >= 8.
+ *
+ * The higher clock rate of timer 4 makes it a better choice than the
+ * other timers for use in gettimeoffset(), while the fact that it can't
+ * generate interrupts means we don't have to worry about not being able
+ * to use this timer for something else. We also use timer 4 for keeping

-/* Ways we can get here:
- *
- * 1) Nucleus loads and stores to/from PA-->VA direct mappings at tl>1.
- * 2) Nucleus loads and stores to/from user/kernel window save areas.
- * 3) VPTE misses from dtlb_base and itlb_base.
- *
- * We need to extract out the PMD and PGDIR indexes from the
- * linear virtual page table access address. The PTE index
- * is at the bottom, but we are not concerned with it. Bits
- * 0 to 2 are clear since each PTE is 8 bytes in size. Each
- * PMD and PGDIR entry are 4 bytes in size. Thus, this
- * address looks something like:
- *
- * |---------------------------------------------------------------|
- * | ... | PGDIR index | PMD index | PTE index | |
- * |---------------------------------------------------------------|
- * 63 F E D C B A 3 2 0 <- bit nr
- *
- * The variable bits above are defined as:
- * A --> 3 + (PAGE_SHIFT - log2(8))
- * --> 3 + (PAGE_SHIFT - 3) - 1
- * (ie. this is "bit 3" + PAGE_SIZE - size of PTE entry in bits - 1)
- * B --> A + 1
- * C --> B + (PAGE_SHIFT - log2(4))
- * --> B + (PAGE_SHIFT - 2) - 1
- * (ie. this is "bit B" + PAGE_SIZE - size of PMD entry in bits - 1)
- * D --> C + 1
- * E --> D + (PAGE_SHIFT - log2(4))
- * --> D + (PAGE_SHIFT - 2) - 1
- * (ie. this is "bit D" + PAGE_SIZE - size of PGDIR entry in bits - 1)
- * F --> E + 1
- *
- * (Note how "B" always evalutes to PAGE_SHIFT, all the other constants
- * cancel out.)
- *
- * For 8K PAGE_SIZE (thus, PAGE_SHIFT of 13) the bit numbers are:
- * A --> 12
- * B --> 13
- * C --> 23
- * D --> 24
- * E --> 34
- * F --> 35
- *
- * For 64K PAGE_SIZE (thus, PAGE_SHIFT of 16) the bit numbers are:
- * A --> 15
- * B --> 16
- * C --> 29
- * D --> 30
- * E --> 43
- * F --> 44
- *
- * Because bits both above and below each PGDIR and PMD index need to
- * be masked out, and the index can be as long as 14 bits (when using a
- * 64K PAGE_SIZE, and thus a PAGE_SHIFT of 16), we need 3 instructions
- * to extract each index out.
- *
- * Shifts do not pair very well on UltraSPARC-I, II, IIi, and IIe, so
- * we try to avoid using them for the entire operation. We could setup
- * a mask anywhere from bit 31 down to bit 10 using the sethi instruction.
- *
- * We need a mask covering bits B --> C and one covering D --> E.
- * For 8K PAGE_SIZE these masks are 0x00ffe000 and 0x7ff000000.
- * For 64K PAGE_SIZE these masks are 0x3fff0000 and 0xfffc0000000.
- * The second in each set cannot be loaded with a single sethi
- * instruction, because the upper bits are past bit 32. We would
- * need to use a sethi + a shift.
- *
- * For the time being, we use 2 shifts and a simple "and" mask.
- * We shift left to clear the bits above the index, we shift down
- * to clear the bits below the index (sans the log2(4 or 8) bits)
- * and a mask to clear the log2(4 or 8) bits. We need therefore
- * define 4 shift counts, all of which are relative to PAGE_SHIFT.
- *
- * Although unsupportable for other reasons, this does mean that
- * 512K and 4MB page sizes would be generaally supported by the
- * kernel. (ELF binaries would break with > 64K PAGE_SIZE since
- * the sections are only aligned that strongly).
- *
- * The operations performed for extraction are thus:
- *
- * ((X << FOO_SHIFT_LEFT) >> FOO_SHIFT_RIGHT) & ~0x3
