yet another build error for NIOS II (which may very well affect
other architectures):
...
CC arch/nios2nommu/kernel/asm-offsets.s
arch/nios2nommu/kernel/asm-offsets.c: In function `main':
arch/nios2nommu/kernel/asm-offsets.c:34: error: structure has no member named `thread_info'
make[2]: *** [arch/nios2nommu/kernel/asm-offsets.s] Error 1
make[1]: *** [prepare0] Error 2
make[1]: Leaving directory `/home/rpjday/nios2/uclinux/uClinux-dist-cvs/linux-2.6.x'
make: *** [linux] Error 1
$
yes, that's a problem since "thread_info" has been renamed to
"stack", as per this:
http://lkml.org/lkml/2007/4/30/551
which will clearly cause problems in that asm-offsets.c file:
int main(void)
{
/* offsets into the task struct */
DEFINE(TASK_STATE, offsetof(struct task_struct, state));
DEFINE(TASK_FLAGS, offsetof(struct task_struct, flags));
DEFINE(TASK_PTRACE, offsetof(struct task_struct, ptrace));
DEFINE(TASK_BLOCKED, offsetof(struct task_struct, blocked));
DEFINE(TASK_THREAD, offsetof(struct task_struct, thread));
DEFINE(TASK_THREAD_INFO, offsetof(struct task_struct, thread_info)); ... uh oh ...
so the obvious question is, what *should* that DEFINE look like? is
it actually wanting to refer to thread_info itself? or to the stack?
rday
Like this:
DEFINE(TASK_THREAD_INFO, offsetof(struct task_struct, stack));
arch/nios2nommu/kernel/process.c also need an update (if you've not already changed it):
