* [PARISC] Fix BLK_BOUNCE_HIGH on parisc by initializing max_low_pfnGrant Grundler2006-01-10
| | | | | | | | | max_low_pfn was not being set in arch/parisc/mm/init.c, causing severe problems whenever anything tried to use BLK_BOUNCE_HIGH. Set it to max_pfn like other similar architectures do. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Truncate overlapping PAT PDC reported rangesGrant Grundler2006-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Deal with overlapping LBA MMIO resources, rp3440 PDC BUG: PDC reports lmmio range for the last rope that overlaps with the CPU HPA. Console output was: ... Found devices: 1. Storm Peak Fast at 0xfffffffffe798000 [152] { 0, 0x0, 0x889, 0x00004 } 2. Storm Peak Fast at 0xfffffffffe799000 [153] { 0, 0x0, 0x889, 0x00004 } ... FAILED: lba_fixup_bus() request for lmmio_space [fffffffff0000000/fffffffffecffffe] Output is now: LBA: Truncating lmmio_space [fffffffff0000000/fffffffffecffffe] to [fffffffff0000000,fffffffffe797fff] My only concern with this patch is how C8000 (PAT PDC) will report elmmio ranges when a gfx card is installed. I'll have to test this another day.

| | | | | | | | | | | | | | | | | | We're starting a number of big applications (memory footprint app. 1MByte) on our Arcturus uC5272. Therefore memory fragmentation is a real pain for us. We've switched to uClinux-2.4.27-uc1 and found that page_alloc2 fragments the memory heavily. Digging into it we found a bug in the find_next_zero_bit function in the m68knommu/bitops.h file. if the size isn't a multiple of 32 than the upper bits of the last word to be searched should be masked. But the functions masks the lower bits of the last word because it uses a right shift instead of a left shift operator.

* [PATCH] m68knommu: fix a5 reg corruption in signal handlersGreg Ungerer2006-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch adapted from a posting by Andrea Tarani which was pointed out to me by Bernardo Innocenti. Thanks to both of them for their help and patience. The original posting is here: http://mailman.uclinux.org/pipermail/uclinux-dev/2005-July/033543.html The problem first manifest itself as busybox ping terminating with an "Illegal instruction". I reduced this to a test case and found that variable size arrays allocated on the stack could lead to stacks not aligned on 32 bit boundaries. For the Coldfire this proved fatal. Having been pointed out this patch by Bernardo, I applied it and it fixed the first test case. I then went back to busybox's ping. This still failed with "Illegal instruction", but in a different way. Before it depended on the size allocated for the ping buffer, now it happened every time. I also found it depended on optimisation level (gcc-3.4.0) -Os was okay but not -O2. After a lot of looking, it turned out that register a5 was being corrupted by the signal handler (after applying the patch). I re-worked the patch a bit to save/restore a5 and now all seems well.
