Make use of def_bool and def_tristate where possible and add sensible defaults to the config symbols where applicable. This shortens the defconfig file by another ~40 lines. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

---help---
|
|
This option restricts access to /dev/mem. If this option is
|
|
disabled, you allow userspace access to all memory, including
|
|
kernel and userspace memory. Accidental memory access is likely
|
|
to be disastrous.
|
|
Memory access is required for experts who want to debug the kernel.
|
|
|
|
If you are unsure, say Y.

prompt "Strict user copy size checks"
|
|
---help---
|
|
Enabling this option turns a certain set of sanity checks for user
|
|
copy operations into compile time warnings.
|
|
|
|
The copy_from_user() etc checks are there to help test if there
|
|
are sufficient security checks on the length argument of
|
|
the copy operation, by having gcc prove that the argument is
|
|
within bounds.
|
|
|
|
If unsure, or if you run an older (pre 4.4) gcc, say N.
