remove the spurious do_softirq calls from entry.S With these in we were calling do_softirq twice; plus the calls in entry.S took no account of nesting. Signed-off-by:

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. Signed-off-by:

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. From: David Pye <dmp@davidmpye.dyndns.org> Signed-off-by:

2.6.12-rc4-pa3 : first pass at making sure use of RFI conforms to PA 2.0 arch pages F-4 and F-5, PA 1.1 Arch page 3-19 and 3-20. The discussion revolves around all the rules for clearing PSW Q-bit. The hard part is meeting all the rules for "relied upon translation". .align directive is used to guarantee the critical sequence ends more than 8 instructions (32 bytes) from the end of page.

Fix card-mode Dino crashes on 725 (and probably other Snake) systems. Dino was coming up in fatal mode after a warm reboot. Resetting Dino brings it out of fatal mode, so do that if the status register indicates we're in fatal mode. Since this was never observed on any later systems, I presume firmware does this for us on those. Signed-off-by:
