How does HIGHMEM64G differ from HIGHMEM ?

Hi folks,
I've been using FC2 and devel kernels for one of our dual-Opteron
systems and am very happy with recent improvements. Everything works
well for us including:
- AMD IDE interface
- tg3 driver (dual Broadcom BCM5704 GigE)
- 3w_9xxx driver (8-port 3ware SATA card)
The only request I have is that the following be added to the x86_64-SMP
kernel config:
CONFIG_HIGHMEM=y
CONFIG_HIGHMEM64G=y
I've been building custom kernels based on the testing SRPMs with just
this one small change and (for us at least) it works well on:
kernel-2.6.7-1.494
kernel-2.6.8-1.524
kernel-2.6.8-1.533
Would it be possible to make "CONFIG_HIGHMEM64G=y" the default for SMP
x86_64 kernels? I bow to the kernel experts, but it does appear to be a
reasonable default given the likelihood of SMP Opterons having more than
4Gig RAM.
And I'll gladly add this to bugzilla if someone will recommend the best
topic for it.
