2006-06-09kconfig: integrate split config into silentoldconfigRoman Zippel3-4/+4
Now that kconfig can load multiple configurations, it becomes simple to integrate the split config step, by simply comparing the new .config file with the old auto.conf (and then saving the new auto.conf). A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).

2006-06-06[MIPS] Fix sparsemem support.Chad Reese2-3/+2
Move memory_present() in arch/mips/kernel/setup.c. When using sparsemem extreme, this function does an allocate for bootmem. This would always fail since init_bootmem hasn't been called yet. Move memory_present after free_bootmem. This only marks actual memory ranges as present instead of the entire address space.

2006-06-05[PATCH] alpha: SMP IRQ routing fixIvan Kokshaysky4-15/+8
From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> After removal of fixup_cpu_present_map() function Alpha ended up with an empty cpu_present_map, so secondary CPUs on SMP systems are not being started. Worse, on some platforms we route interrupts to secondary CPUs using cpu_possible_map which is still populated properly. As a result, these interrupts go nowhere so the machines like DP264 aren't able to boot even with a primary CPU. Fixed basically by s/cpu_present_mask/cpu_present_map/.

2006-06-02[ARM] 3540/1: ixp23xx: deal with gap in interrupt bitmasksLennert Buytenhek1-3/+15
Patch from Lennert Buytenhek On the ixp23xx, the microengine thread interrupt sources are numbered 56..119, but their mask/status bits are located in bit positions 64..127 in the various registers in the interrupt controller (bit positions 56..63 are unused.) We don't deal with this, so currently, when asked to enable IRQ 64, we will enable IRQ 56 instead. The only interrupts >= 64 are the thread interrupt sources, and there are no in-tree users of those yet, so this is fortunately not a big problem, but this needs fixing anyway.

2006-06-01[MIPS] Fix deadlock on MP with cache aliases.Ralf Baechle1-9/+30
A proper fix would involve introducing the notion of shared caches but at this stage of 2.6.17 that's going to be too intrusive and not needed for current hardware; aside I think some discussion will be needed. So for now on the affected SMP configurations which happen to suffer from cache aliases we make use of the fact that a single cache will be shared by all processors. This solves the deadlock issue and will improve performance by getting rid of the smp_call_function overhead. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

The following code does not handle the edge condition correctly: while (bad_addr(&addr, size) && addr+size < ei->addr + ei->size) ; last = addr + size; if ( last > ei->addr + ei->size ) continue; The second statement in the while loop needs to be a <= b so that it is the logical negavite of the if (a > b) outside it. It needs to read: while (bad_addr(&addr, size) && addr+size <= ei->addr + ei->size) ; In the case that failed bad_addr was returning an address that is exactly size bellow the end of the e820 range.
