#ifndef _CR_KSYMS_H
#define _CR_KSYMS_H 1
/* Give the linker a literal address for a symbol.
* Note that the case is preserved in the preprocessor symbols.
*
* Note that the CR_IMPORT_K*() must come AFTER the last use in a given
* source file, or in a separate source file. Otherwise, the assembler
* may generate PC-relative calls that the ELF-validation code in some
* 2.6.x kernels (e.g. FC3) will reject. To meet this requirement,
* BLCR is currently putting all IMPORTS in a separate kernel module.
*
*
* Example:
* #if defined(CR_KDATA_foo) && CR_KDATA_foo
* CR_IMPORT_KDATA(foo)
* #endif
*
* Or, if you have the address
* _CR_IMPORT_KDATA(foo, 0xabcd0123)
