-/* 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

- * The VPTE base value is completely magic, but note that
- * few places in the kernel other than these TLB miss
- * handlers know anything about the VPTE mechanism or
- * how it works (see VPTE_SIZE, TASK_SIZE and PTRS_PER_PGD).
- * Consider the 44-bit VADDR Ultra-I/II case as an example:
- *
- * VA[0 :  (1<<43)] produce VPTE index [%g3                        :   0]
- * VA[0 : -(1<<43)] produce VPTE index [%g3-(1<<(43-PAGE_SHIFT+3)) : %g3]
- *
- * For Cheetah's 64-bit VADDR space this is:
- *
- * VA[0 :  (1<<63)] produce VPTE index [%g3                        :   0]
- * VA[0 : -(1<<63)] produce VPTE index [%g3-(1<<(63-PAGE_SHIFT+3)) : %g3]
- *
- * If you're paying attention you'll notice that this means half of
- * the VPTE table is above %g3 and half is below, low VA addresses
- * map progressively upwards from %g3, and high VA addresses map
- * progressively upwards towards %g3.  This trick was needed to make
- * the same 8 instruction handler work both for Spitfire/Blackbird's
- * peculiar VA space hole configuration and the full 64-bit VA space
- * one of Cheetah at the same time.
