VmallocTotal meminfo

[Jan Engelhardt <jengelh@linux01.gwdg.de>]

Hi,


/proc/meminfo:
MemTotal:       256656 kB
MemFree:         32480 kB
...
LowTotal:       256656 kB
LowFree:         32480 kB
SwapTotal:      530136 kB
SwapFree:       530136 kB
...
VmallocTotal:   778164 kB
VmallocUsed:     22468 kB
VmallocChunk:   755404 kB

What's the VmallocTotal telling me? How is it calculated?
I ask because running a surprisingly modern Linux on a surprisingly ancient 
machine results in VmallocTotal being somewhere in the 1-gigabyte range, which 
can _never_ ever be.
