Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * PowerPC64 atomic bit operations.
+ * Dave Engebretsen, Todd Inglett, Don Reed, Pat McCarthy, Peter Bergner,
+ * Anton Blanchard
+ *
+ * Originally taken from the 32b PPC code. Modified to use 64b values for
+ * the various counters & memory references.
+ *
+ * Bitops are odd when viewed on big-endian systems. They were designed
+ * on little endian so the size of the bitset doesn't matter (low order bytes
+ * come first) as long as the bit in question is valid.
+ *
+ * Bits are "tested" often using the C expression (val & (1<<nr)) so we do
+ * our best to stay compatible with that. The assumption is that val will
+ * be unsigned long for such tests. As such, we assume the bits are stored
+ * as an array of unsigned long (the usual case is a single unsigned long,
+ * of course). Here's an example bitset with bit numbering:
+ *
+ * |63..........0|127........64|195.......128|255.......196|
+ *
+ * This leads to a problem. If an int, short or char is passed as a bitset
+ * it will be a bad memory reference since we want to store in chunks
+ * of unsigned long (64 bits here) size.
+ *
+ * There are a few little-endian macros used mostly for filesystem bitmaps,
+ * these work on similar bit arrays layouts, but byte-oriented:
+ *
+ * |7...0|15...8|23...16|31...24|39...32|47...40|55...48|63...56|
+ *
+ * The main difference is that bit 3-5 in the bit number field needs to be
+ * reversed compared to the big-endian bit fields. This can be achieved
+ * by XOR with 0b111000 (0x38).
+ *

+ * - controller 2 offsets are all even (2x offsets for controller 1)
+ * - page registers for 5-7 don't use data bit 0, represent 128K pages
+ * - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * On PReP, DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * On CHRP, the W83C553F (and VLSI Tollgate?) support full 32 bit addressing.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ * Address mapping for channels 0-3:
+ *
+ * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
+ * | ... | | ... | | ... |
+ * | ... | | ... | | ... |
+ * | ... | | ... | | ... |
+ * P7 ... P0 A7 ... A0 A7 ... A0
+ * | Page | Addr MSB | Addr LSB | (DMA registers)
+ *
+ * Address mapping for channels 5-7:
+ *
+ * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
+ * | ... | \ \ ... \ \ \ ... \ \
+ * | ... | \ \ ... \ \ \ ... \ (not used)
+ * | ... | \ \ ... \ \ \ ... \
+ * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
+ * | Page | Addr MSB | Addr LSB | (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

+ * ===============

+ * We first generate a 36-bit "proto-VSID". For kernel addresses this
+ * is equal to the ESID, for user addresses it is:
+ * (context << 15) | (esid & 0x7fff)
+ *
+ * The two forms are distinguishable because the top bit is 0 for user
+ * addresses, whereas the top two bits are 1 for kernel addresses.
+ * Proto-VSIDs with the top two bits equal to 0b10 are reserved for
+ * now.
+ *
+ * The proto-VSIDs are then scrambled into real VSIDs with the
+ * multiplicative hash:
+ *
+ * VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
+ * where VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
+ * VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
+ *
+ * This scramble is only well defined for proto-VSIDs below
+ * 0xFFFFFFFFF, so both proto-VSID and actual VSID 0xFFFFFFFFF are
+ * reserved. VSID_MULTIPLIER is prime, so in particular it is
+ * co-prime to VSID_MODULUS, making this a 1:1 scrambling function.
+ * Because the modulus is 2^n-1 we can compute it efficiently without
+ * a divide or extra multiply (see below).
+ *
+ * This scheme has several advantages over older methods:
+ *
+ * - We have VSIDs allocated for every kernel address
+ * (i.e. everything above 0xC000000000000000), except the very top
+ * segment, which simplifies several things.
+ *
+ * - We allow for 15 significant bits of ESID and 20 bits of
+ * context for user addresses. i.e. 8T (43 bits) of address space for
+ * up to 1M contexts (although the page table structure and context
+ * allocation will need changes to take advantage of this).
+ *
+ * - The scramble function gives robust scattering in the hash
+ * table (at least based on some initial results). The previous
+ * method was more susceptible to pathological cases giving excessive
+ * hash collisions.
+ */
+
+/*
+ * WARNING - If you change these you must make sure the asm
+ * implementations in slb_allocate(), do_stab_bolted and mmu.h
