/* The object file of "table.c" contains most kernel data. Variables that
|
|
* are declared in the *.h files appear with EXTERN in front of them, as in
|
|
*
|
|
* EXTERN int x;
|
|
*
|
|
* Normally EXTERN is defined as extern, so when they are included in another
|
|
* file, no storage is allocated. If EXTERN were not present, but just say,
|
|
*
|
|
* int x;
|
|
*
|
|
* then including this file in several source files would cause 'x' to be
|
|
* declared several times. While some linkers accept this, others do not,
|
|
* so they are declared extern when included normally. However, it must be
|
|
* declared for real somewhere. That is done here, by redefining EXTERN as
|
|
* the null string, so that inclusion of all *.h files in table.c actually
|
|
* generates storage for them.
|
|
*
|
|
* Various variables could not be declared EXTERN, but are declared PUBLIC
|
|
* or PRIVATE. The reason for this is that extern variables cannot have a
|
|
* default initialization. If such variables are shared, they must also be
|
|
* declared in one of the *.h files without the initialization. Examples
|
|
* include 'boot_image' (this file) and 'idt' and 'gdt' (protect.c).

|
* Changes:
|
|
* Nov 22, 2009 rewrite of privilege management (Cristiano Giuffrida)
|
|
* Aug 02, 2005 set privileges and minimal boot image (Jorrit N. Herder)
|
|
* Oct 17, 2004 updated above and tasktab comments (Jorrit N. Herder)
|
|
* May 01, 2004 changed struct for system image (Jorrit N. Herder)
