* i386/i386/db_interface.c (int_regs): Drop gs and fs fields. (kdb_kentry): Get fs and gs from struct i386_interrupt_state instead of struct int_regs. * i386/i386/kttd_interface.c (int_regs, kttd_netentry): Likewise. * i386/i386/locore.S (all_intrs): Save fs and gs and set them to kernel segment too. (return_to_iret): Restore fs and gs too. (return_to_iret_i): Likewise. (ast_from_interrupt): Set fs and gs to kernel segment too. (kdb_from_iret): Don't save/restore fs and gs either. (ttd_from_iret): Likewise. * i386/i386/thread.h (i386_interrupt_state): Add gs and fs fields. * linux/src/include/asm-i386/irq.h (SAVE_ALL): Set gs to kernel segment too.
