Hi,
New binutils has
./bfd/elf64-x86-64.c:#define ELF_MAXPAGESIZE 0x200000
as described in
http://sourceware.org/ml/binutils/2006-05/msg00279.html
This causes problems for our kernel which tries to link at 0xffffffff80100000.
Fixes are
1) keep this start text address by adding -z max-page-size=0x100000; or
2) by allowing the new maxpage alignment with the attached diff. I
suppose that LARGEPAGES could die as a result?
Anyone got any strong preference?
Nick
