Hello there,
I just tried to compile Linux kernel 2.6.18.3 with the Intel C
C compiler.
The compiler said
arch/x86_64/mm/numa.c(124): remark #593: variable "bootmap_size" was
set but never used
Actually it looks like a real bug -- probably added recently with the
new bootmap code.
The bootmap should be reserved based on that size.
I checked the arch-independent sizing patches submitted related to x86_64
and no line is changed that does anything with bootmap_size so that ruled
out an obvious candidate. I did a diff on a grep for bootmap_size in
arch/x86_64 and found that there is no difference in usage between 2.6.18
and 2.6.19-rc6. Both call reserve_bootmem(bootmap, bootmap_size) which has
changed. However, the changes seem to be more cosmetic than anything else
using PFN_DOWN and PFN_UP instead of some_value/PAGE_SIZE so it's not
super-clear where the warning is coming from.
