1 /* The object file of "table.c" contains most kernel data. Variables that 2 * are declared in the *.h files appear with EXTERN in front of them, as in 3 * 4 * EXTERN int x; 5 * 6 * Normally EXTERN is defined as extern, so when they are included in another 7 * file, no storage is allocated. If EXTERN were not present, but just say, 8 * 9 * int x; 10 * 11 * then including this file in several source files would cause 'x' to be 12 * declared several times. While some linkers accept this, others do not, 13 * so they are declared extern when included normally. However, it must be 14 * declared for real somewhere. That is done here, by redefining EXTERN as 15 * the null string, so that inclusion of all *.h files in table.c actually 16 * generates storage for them. 17 * 18 * Various variables could not be declared EXTERN, but are declared PUBLIC 19 * or PRIVATE. The reason for this is that extern variables cannot have a 20 * default initialization. If such variables are shared, they must also be 21 * declared in one of the *.h files without the initialization. Examples 22 * include 'boot_image' (this file) and 'idt' and 'gdt' (protect.c). 23 * 24 * Changes: 25 * Nov 22, 2009 rewrite of privilege management (Cristiano Giuffrida) 26 * Aug 02, 2005 set privileges and minimal boot image (Jorrit N.
