Linux-2.6.12-rc2v2.6.12-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!

+ This enables support for systems with more than one CPU. If you have

+ you have a system with more than one CPU, say Y.
+
+ If you say N here, the kernel will run on single and multiprocessor
+ machines, but will use only one CPU of a multiprocessor machine. If
+ you say Y here, the kernel will run on many, but not all,
+ singleprocessor machines. On a singleprocessor machine, the kernel
+ will run faster if you say N here.
+
+ See also the <file:Documentation/smp.txt>,
+ <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available

+ * - 715/Mirage device paths have a dummy device between Lasi and its children
+ * - The EISA adapter may show up as a sibling or child of Wax
+ * - Dino has an optionally functional serial port. If firmware enables it,
+ * it shows up as a child of Dino. If firmware disables it, the buswalk
+ * finds it and it shows up as a child of Cujo
+ * - Dino has both parisc and pci devices as children
+ * - parisc devices are discovered in a random order, including children
+ * before parents in some cases.

+ * stack. If it is, call the get_stack_use_r30 macro

+ * and we can sleep in those cases.
+ *
+ * Note that we use shadowed registers for temps until
+ * we can save %r26 and %r29. %r26 is used to preserve
+ * %r8 (a shadowed register) which temporarily contained
+ * either the fault type ("code") or the eirr. We need
+ * to use a non-shadowed register to carry the value over
+ * the rfir in virt_map. We use %r26 since this value winds
+ * up being passed as the argument to either do_cpu_irq_mask
+ * or handle_interruption. %r29 is used to hold a pointer
+ * the register save area, and once again, it needs to
+ * be a non-shadowed register so that it survives the rfir.

+/* I think it would be in everyone's best interest to follow this
+ * guidelines when writing PDC wrappers:
+ *
+ * - the name of the pdc wrapper should match one of the macros
+ * used for the first two arguments
+ * - don't use caps for random parts of the name
+ * - use the static PDC result buffers and "copyout" to structs
+ * supplied by the caller to encapsulate alignment restrictions
+ * - hold pdc_lock while in PDC or using static result buffers
+ * - use __pa() to convert virtual (kernel) pointers to physical
+ * ones.
+ * - the name of the struct used for pdc return values should equal
+ * one of the macros used for the first two arguments to the
+ * corresponding PDC call
+ * - keep the order of arguments
+ * - don't be smart (setting trailing NUL bytes for strings, return
+ * something useful even if the call failed) unless you are sure
+ * it's not going to affect functionality or performance
+ *
+ * Example:
+ * int pdc_cache_info(struct pdc_cache_info *cache_info )
+ * {
+ * int retval;
+ *
+ * spin_lock_irq(&pdc_lock);
+ * retval = mem_pdc_call(PDC_CACHE,PDC_CACHE_INFO,__pa(cache_info),0);

+ * We are not doing SEGREL32 handling correctly. According to the ABI, we

+ * if (is_init(me, (void *)val))
+ * val -= (uint32_t)me->module_init;
+ * else
+ * val -= (uint32_t)me->module_core;
+ * However, SEGREL32 is used only for PARISC unwind entries, and we want
+ * those entries to have an absolute address, and not just an offset.
+ *
+ * The unwind table mechanism has the ability to specify an offset for
+ * the unwind table; however, because we split off the init functions into
+ * a different piece of memory, it is not possible to do this using a
+ * single offset. Instead, we use the above hack for now.

+ * This driver programs the PCX-U/PCX-W performance counters
+ * on the PA-RISC 2.0 chips. The driver keeps all images now
+ * internally to the kernel to hopefully eliminate the possiblity
+ * of a bad image halting the CPU. Also, there are different
+ * images for the PCX-W and later chips vs the PCX-U chips.
+ *
+ * Only 1 process is allowed to access the driver at any time,
+ * so the only protection that is needed is at open and close.
+ * A variable "perf_enabled" is used to hold the state of the
+ * driver. The spinlock "perf_lock" is used to protect the
+ * modification of the state during open/close operations so
+ * multiple processes don't get into the driver simultaneously.
+ *
+ * This driver accesses the processor directly vs going through
+ * the PDC INTRIGUE calls. This is done to eliminate bugs introduced
+ * in various PDC revisions. The code is much more maintainable
+ * and reliable this way vs having to debug on every version of PDC
+ * on every box.

+;* Name: perf_rdr_shift_in_W

+;* Description:
+;* This routine shifts data in from the RDR in arg0 and returns
+;* the result in ret0. If the RDR is <= 64 bits in length, it
+;* is shifted shifted backup immediately. This is to compensate
+;* for RDR10 which has bits that preclude PDC stack operations
+;* when they are in the wrong state.
+;*
+;* Arguments:
+;* arg0 : rdr to be read
+;* arg1 : bit length of rdr
+;*
+;* Returns:
+;* ret0 = next 64 bits of rdr data from staging register
+;*
+;* Register usage:
+;* arg0 : rdr to be read
+;* arg1 : bit length of rdr
+;* %r24 - original DR2 value
+;* %r1 - scratch
+;* %r29 - scratch
+;*

+;* Name: rdr_shift_in_U

+;* Description:
+;* This routine shifts data in from the RDR in arg0 and returns
+;* the result in ret0. If the RDR is <= 64 bits in length, it
+;* is shifted shifted backup immediately. This is to compensate
+;* for RDR10 which has bits that preclude PDC stack operations
+;* when they are in the wrong state.
+;*
+;* Arguments:
+;* arg0 : rdr to be read
+;* arg1 : bit length of rdr
+;*
+;* Returns:
+;* ret0 = next 64 bits of rdr data from staging register
+;*
+;* Register usage:
+;* arg0 : rdr to be read
+;* arg1 : bit length of rdr
+;* %r24 - original DR2 value
+;* %r23 - DR2 | DR2_SLOW_RET

+ * Several strategies are tried to try to get the best performance for various
+ * conditions. In the optimal case, we copy 64-bytes in an unrolled loop using
+ * fp regs. This is followed by loops that copy 32- or 16-bytes at a time using
+ * general registers. Unaligned copies are handled either by aligning the
+ * destination and then using shift-and-write method, or in a few cases by
+ * falling back to a byte-at-a-time copy.
+ *
+ * I chose to implement this in C because it is easier to maintain and debug,
+ * and in my experiments it appears that the C code generated by gcc (3.3/3.4
+ * at the time of writing) is fairly optimal. Unfortunately some of the
+ * semantics of the copy routine (exception handling) is difficult to express
+ * in C, so we have to play some tricks to get it to work.
+ *
+ * All the loads and stores are done via explicit asm() code in order to use
+ * the right space registers.
+ *
+ * Testing with various alignments and buffer sizes shows that this code is
+ * often >10x faster than a simple byte-at-a-time copy, even for strangely
+ * aligned operands. It is interesting to note that the glibc version
+ * of memcpy (written in C) is actually quite fast already. This routine is
+ * able to beat it by 30-40% for aligned copies because of the loop unrolling,
+ * but in some cases the glibc version is still slightly faster. This lends
+ * more credibility that gcc can generate very good code as long as we are
+ * careful.
+ *
+ * TODO:
+ * - cache prefetching needs more experimentation to get optimal settings
+ * - try not to use the post-increment address modifiers; they create additional
+ * interlocks
+ * - replace byte-copy loops with stybs sequences
