The call to io_block_mapping was creating an invalid BAT entry because the value of BCSR_SIZE (32K) is too small to be used in a BAT (128K min). This change removes the io_block_mapping call since these registers can easily be mapped using ioremap at the point of use. Signed-off-by:

The error checking for emulation of load string instructions was overly generous and would cause certain valid forms of the instructions to be treated as illegal. We drop the range checking since the architecture allows this to be boundedly undefined. Tests on CPUs that support these instructions appear not do cause illegal instruction traps on range errors and just allow the execution to occur. Thanks to Kim Phillips for debugging this and figuring out what real HW was doing. Signed-off-by:

This patch adds on-chip PCI bridge support for the PQ2 family. The incomplete existent code is updated with interrupt handling stuff and board-specific bits for 8272ADS and PQ2FADS; the related files were renamed (from m8260_pci to m82xx_pci) to be of more generic fashion. This is tested with 8266ADS and 8272ADS, should work on PQ2FADS as well. Signed-off-by:

Some debug registers needed to be initialized early on to allow proper support for KGDB. Additionally, we need to setup the ppc.md_early_serial_map function pointer on boards that have serial support for KGDB. Signed-off-by:

The existing make rule when building a uImage would check to see if the image file existed to report 'is ready' or 'not made'. However make appeared to compute the file list before the rule was executed. Signed-off-by:

This var is currently useless, as it's apparent from reading the code. Until 2.6.11 it was used in some code related to jail mode, in the same proc.: if(jail){ while(!reading) sched_yield(); } jail mode has been dropped, together with that use, so let's finish dropping this. Also, remove some other useless definitions I met. Acked-by:Jeff Dike <jdike@addtoit.com> Signed-off-by:

Fix it a bit (after some cross checking with "man arch_prctl"). There were: *) typos FS/GS and back *) FS in place of FS_BASE (and the same for GS) *) the procedure used put_user on &addr, where addr was the parameter (i.e. changed its param with put_user, completely useless) rather than interpreting addr as a pointer, as requested in this case (see the man page).

After porting this fixlet to UML: http://linux.bkbits.net:8080/linux-2.5/cset@41791ab52lfMuF2i3V-eTIGRBbDYKQ , I've also added a warning which should refuse compilation with insane values for PREEMPT_ACTIVE... maybe we should simply move PREEMPT_ACTIVE out of architectures using GENERIC_IRQS.

Port Paulus's ppc64 fix to sh: When the generic IRQ stuff went in, it seems that HARDIRQ_BITS got bumped from 9 (for ppc64) up to 12. Consequently, the PREEMPT_ACTIVE bit is now within HARDIRQ_MASK, and I get in_interrupt() falsely returning true when PREEMPT_ACTIVE is set, and thus a BUG_ON tripping in arch/ppc64/mm/tlb.c.

Paolo 'Blaisorblade' Giarrusso authored
Until now, FRAME_POINTER was set = DEBUG_INFO for UML. Change it to be the default way, so that it can be enabled alone (for instance to get better backtraces on crashes). The call-trace dumper which uses the frame pointer is not yet in, I'm going to introduce it in a separate patch. Signed-off-by:

On Nov 16 2004 a change to intelfbdrv.c was commited (as part of 0.9.2 it looks like) that added __initdata to all of the module param variables that seems to create the opportunity for an oops. I've recently been chasing an OOPS (http://marc.theaimsgroup.com/?l=linux-kernel&m=111552250920370&w=2) I created by reading every file on the /sys file system and I've traced it back to this code in the intelfbdrv. Though I had root privs in my initial problem report, it turns out they are un-necessary to generate the oops - all you've got to do is "cat /sys/module/intelfb/parameters/mode" enough times and eventually it will oops. This is because sysfs automatically exports all module_param declarations to the sysfs file system.. which means those variables can be dynamically evaluated at any later time, which of course means marking them __initdata is a bad idea ;).. when they happen to be char *'s it is an especially bad idea ;). Applying the patch below clears up the OOPS for me. Signed-off-by:

Recent kernels occasionally trigger a PMU timeout on some mac laptops, typically on wakeup from sleep. This seem to be caused by either a too big latency caused by the cpufreq switch on wakeup from sleep or by an interrupt beeing lost due to the reset of the interrupt controller done during wakeup. This patch makes that code more robust by stopping PMU auto poll activity around cpufreq changes on machines that use the PMU for such changes (long latency switching involving a CPU hard reset and flush of all caches) and by removing the reset of the open pic interrupt controller on wakeup (that can cause the loss of an interrupt and Darwin doesn't do it, so it must not be necessary).

This fixes 'smp_num_siblings' value on the systems with a buggy bios, which sets number of siblings to '2' even when HT is disabled. (more details are at http://bugzilla.kernel.org/show_bug.cgi?id=4359) I am planning to do more cleanup in this area (like moving smp_num_siblings to per cpuinfo) shortly. Signed-off-by:

The "unhandled interrupts" catcher, note_interrupt(), increments a global desc->irq_count and grossly damages scaling of very large systems, e.g., >192p ia64 Altix, because of this highly contented cacheline, especially for timer interrupts. 384p is severely crippled, and 512p is unuseable. All calls to note_interrupt() can be disabled by booting with "noirqdebug", but this disables the useful interrupt checking for all interrupts. I propose eliminating note_interrupt() for all per-CPU interrupts. This was the behavior of linux-2.6.10 and earlier, but in 2.6.11 a code restructuring added a call to note_interrupt() for per-CPU interrupts. Besides, note_interrupt() is a bit racy for concurrent CPU calls anyway, as the desc->irq_count++ increment isn't atomic (which, if done, would make scaling even worse). Signed-off-by:
