| * | [POWERPC] ppc405 Fix arithmatic rollover bug when memory size under 16M | Grant Likely | 2007-11-01 | 1 | -9/+8 |
| | | | | | | | | | | | | | | | | | | mmu_mapin_ram() loops over total_lowmem to setup page tables. However, if total_lowmem is less that 16M, the subtraction rolls over and results in a number just under 4G (because total_lowmem is an unsigned value). This patch rejigs the loop from countup to countdown to eliminate the bug. Special thanks to Magnus Hjorth who wrote the original patch to fix this bug. This patch improves on his by making the loop code simpler (which also eliminates the possibility of another rollover at the high end) and also applies the change to arch/powerpc.

| * | [POWERPC] Rename 4xx paths to 40x | Josh Boyer | 2007-08-20 | 1 | -0/+135 |
| 4xx is a bit of a misnomer for certain things, as they really apply to PowerPC 40x only. Rename some of the files to clean this up. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Acked-by: David Gibson <david@gibson.dropbear.id.au> | |||||
