Now:
Jesse released a new patch and I tried if for fun on 2.6.22-rc6
It looks like the patch is releasing memory rather than trimming it:
[...]
Jun 27 12:22:56 corneille kernel: **** MTRRs don't cover all of memory,
trimmed -65536 pages
[...]
From Jesse's patch:
+ unsigned long i, base, size, highest_addr = 0, def, dummy;
[...]
+ printk(KERN_WARNING "**** MTRRs don't cover all of "
+ "memory, trimmed %ld pages\n", end_pfn -
+ (highest_addr >> PAGE_SHIFT));
Since both end_pfn (from arch/x86_64/kernel/e820.c) and highest_addr
are unsigned long, maybe the problem is just that %ld in the kprintf
format string? Shouldn't that be %lu?
