| |
On i386, SOFTWARE_SUSPEND requires the CPU to have PSE support, but DEBUG_PAGEALLOC disables PSE. Thus, allowing both options to be enabled simultaneously makes no sense. This patch disables DEBUG_PAGEALLOC if SOFTWARE_SUSPEND is enabled; it also displays a comment to briefly explain why DEBUG_PAGEALLOC is missing in that case.
I have tested this patch against oldconfig and menuconfig on 2.6.11-bk2.
