* x86-64: reduce symbol table sizeKeir Fraser2009-07-131-6/+10
| | | | | | | | | | | | | | With all of Xen's symbols sitting within a 2Gb range on x86-64, they can be referred to by the kallsyms-like offset table using 4- instead of 8-byte slots. The marker table can use 4-byte slots in all cases, just like the table entry counts can (though that's only a minor improvement). If ia64's PERCPU_ADDR got moved down to (KERNEL_START + 2Gb - PERCPU_PAGE_SIZE), it could also utilize the more compact form. Signed-off-by: Jan Beulich <jbeulich@novell.com>
* [XEN] Remove weak-extern definitions from symbols.c.kfraser@localhost.localdomain2006-09-281-0/+16
Instead we have an explicit set of dummy symbol definitions for the inital link of the Xen image. Signed-off-by: Keir Fraser <keir@xensource.com>
