Subject: memmap exclude boot command: how to check if it was indeed applied

Hi,

After  hunting an unreproducible bug, I decided to run memtest86+ and 
found that only 8 byte of memory refuse to write the last two digit on 
the last 4GB memory stick.

Memory is at 0x31db357558

So I decided to add a memmap=4K@...00000031db35000 boot options in 
GRUB_CMDLINE_LINUX. But checking dmesg, I see no mention of this page 
being reserved.

PS: CC me I'm not subscribed.
