[9fans] about KTZERO mismatch in mkfile and mem.h

[Yoann Padioleau]

Hi,

in 9/pc/mem.h it says:
/*
 *  Address spaces
 */
#define KZERO           0xF0000000              /* base of kernel address space 
*/
#define KTZERO          (KZERO+0x100000)        /* first address in kernel text 
- 9load sits below */


and in 9/pc/mkfile:
# must match mem.h
APBOOTSTRAP=0xF0003000
KTZERO=0xF0100020


so why the difference? what is this additional 20 for KTZERO?
