This fixes issues with hangs booting an SMP kernel on my C360. Previously serio_interrupt() could be called before the lock in struct serio was initialised.

fixup.S needs to specify .level and use correct LDREG macro. New binutils has a bug where it doesn't "promote" from PA1.0 to PA1.1 correctly when using ",s" completer. remove use of __LP64__ in assembly.h and add some white space.

replace use of "0" with "%r0" since PA 1.1 I/D flush ops only take a general register and not an immediate value for the index field. This just forces the code to always be PA 1.1 "clean".

2.6.12-rc2-pa3 fix copy_user_page_asm to NOT access past end of page. My bad. /o\ Lamont confirmed that instructions following a conditional branch are *alway* executed regardless if the branch is taken or not. Unless they are nullified (which was missing in this case). He also noted: Conditional branches nullify on forward taken branch, and on non-taken backward branch. Note that .+4 is a backwards branch. This makes alot more sense than the giberish in the PA20 arch book. Compiles and boots on both 64-bit (a500) and 32-bit (j6k).

Fix the alloc_slabmgmt panic Hopefully this should also fix a lot of other intermittent kernel bugs. The problem has been around since 2.6.9-rc2-pa6 when we allowed floating point registers to be used in kernel code. The essence of the problem is that gcc prefers to use floating point for integer divides and multiples. Further, it can rely on the values in the no clobber fp regs being correct across a function call. Unfortunately, our task switch function only saves the integer no clobber registers, not the fp ones, so if gcc makes a function call to any function in the kernel which could sleep, the values it is relying on in any no clobber floating point register may be lost. In the case of alloc_slabmgmt, the value of the page offset is being stored in %fr12 across a call to kmem_getpages(), which sleeps if no pages are available. Thus, the offset can be trashed and the slab code can end up with a completely bogus address leading to corruption. Kudos to Randolph who came up with the program to trip this problem at will and thus allowed it to be tracked and fixed.

2.6.12-rc1-pa6 use work queue in LED/LCD driver instead of tasklet. Main advantage is it allows use of msleep() in the led_LCD_driver to "atomically" perform two MMIO writes (CMD, then DATA). Lead to nice cleanup of the main led_work_func() and led_LCD_driver(). Kudos to David for being persistent.

Optimize ext2_find_next_zero_bit. Gives about 25% perf improvement with a rsync test with ext3. Signed-off-by: Randolph Chung <tausq@parisc-linux.org> fix ext3 performance - ext2_find_next_zero() was culprit. Kudos to jejb for pointing out the the possibility that ext2_test_bit and ext2_find_next_zero() may in fact not be enumerating bits in the bitmap because of endianess. Took sparc64 implementation and adapted it to our tree. I suspect the real problem is ffz() wants an unsigned long and was getting garbage in the top half of the unsigned int. Not confirmed but that's what I suspect.

I think header files that might go to user space should use something userspace will know about (__LP64__).
