Hi,
It does annoy me that any 1G i386 machine will end up with 1/8th of the memory as highmem. A patch like this one has been used in various places since the early 2.4 days at least, is there a reason why it isn't merged yet? Note I just hacked this one up, but similar patches abound I'm sure. Bugs are mine.
yes, i made it totally configurable in 2.4 days: 1:3, 2/2 and 3:1 splits were possible. It was a larger patch to enable all this across x86, but the Kconfig portion was removed a bit later because people _frequently_ misconfigured their kernels and then complained about the results.
so for now the trivial solution is to change the "C" to "8" in the following line in include/asm-i386/page.h:
#define __PAGE_OFFSET (0xC0000000)
instead of editing your .config :-)
Maybe we could try the Kconfig solution again, but it'll need alot better documentation, dependency on KERNEL_DEBUG and some heavy warnings all around.
