Use -rlinux_2_4_18 for checkout.

enlarge KERNEL_STACK_SIZE

dear all,

 how to enlarge KERNEL_STACK_SIZE?

 is it enough if i only change 
 the definition of KERNEL_STACK_SIZE in include/asm-mips/processor.h ?

No, other changes would be needed also.  HOWEVER:  It's a very bad idea.
Stacks larger than 8kB require allocation of order 2 or even bigger
pages which will make the kernel unreliable.  I really recommend to stick
with the current 8kB stacks.

[help] exec_usermodehelper() then content of CURRENT is destroyed

[??]

dear all,

1)in our 2.4.18 mips kernel , when we call  exec_usermodehelper() (in
kernel/kmod.c)
the content of CURRENT is destroyed during [page_fault handler loading pages
from storage-device to ram]

which kind of error may cause this problem?
any hint/idea?

2)btw, in some mips linux port,
[syscall] is done by [scall_o32.S]
when [handle_sys] is done,
it will return by [o32_ret_from_sys_call],
[o32_ret_from_sys_call] will do [reschedule] and [signal],
but the question is here it doesn't check whether [syscall] is from
User-space or Kernel-space
if we use [syscall] in kernel-space, and do [signal] after [syscall] return,
won't it cause problem? is this bug of linux code?

thanks alot in advanced!
