modpost: support objects with more than 64k sections
This patch makes modpost able to process object files with more than 64k sections. Needed for huge kernel builds (allyesconfig, for example) with -ffunction-sections. 64k sections handling is covered, for example, by this document: "IA-64 gABI Proposal 74: Section Indexes" http://www.codesourcery.com/public/cxx-abi/abi/prop-74-sindex.html Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com> Signed-off-by: Anders Kaseorg <andersk@mit.edu> Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Andi Kleen <andi@firstfloor.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
