As Reagan said "Trust ... but verify" ... we should make sure BIOS
gave us a good pfn
if (pfn_valid(pfn))
soft_memory_failure_queue(pfn, 0, 0);
else
printk( ...something about
BIOS giving us bad pfn = %lu\n", pfn);
Ah, nice catch - I thought soft_offline_page() takes care of this,
but it sure is good to point a finger at the firmware.
While at it maybe make it pr_warning(FW_BUG or FW_WARN...
Yup - I've made it a pr_warning(FW_WARN... I just sent out a new version
with these changes.
Thanks,
Naveen
