The very strict checks were originally implemented because various early BIOS had largely fictional SRATs, and trusting them blindly caused boot failures or a lot of wasted memory for unnecessary hotplug zones. The wasted memory was mainly a problem with the old memory hotplug implementation that pre-allocated memmaps, that's not a problem anymore. However there may be still some other failure cases. -Andi -- a...@linux.intel.com -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
