module: fix try_then_request_module
Impact: fix wireless modules, broken by acae05156551fd7528fbb616271e672789388e3c
Fix try_then_request_module to use waiting __request_module again.

cyber2000fb.c: use proper method for stopping unload if CONFIG_ARCH_SHARK
Russell explains the __module_get():
> cyber2000fb.c does it in its module initialization function
> to prevent the module (when built for Shark) from being unloaded. It
> does this because it's from the days of 2.2 kernels and no one bothered
> writing the module unload support for Shark.
Since 2.4, the correct answer has been to not define an unload fn.

module_param: invbool should take a 'bool', not an 'int'
It takes an 'int' for historical reasons, and there are only two
users: simply switch it over to bool.
The other user (uvesafb.c) will get a (harmless-on-x86) warning until
the next patch is applied.

commit b45c80a3c89291c75e199d221a43d10040123b1f

module_param: split perm field into flags and perm
Impact: cleanup
Rather than hack KPARAM_KMALLOCED into the perm field, separate it out.
Since the perm field was 32 bits and only needs 16, we don't add bloat.

module_param: add __same_type convenience wrapper for __builtin_types_compatible_p
Impact: new API
__builtin_types_compatible_p() is a little awkward to use: it takes two
types rather than types or variables, and it's just damn long.
(typeof(type) == type, so this works on types as well as vars).

module_param: allow 'bool' module_params to be bool, not just int.
Impact: API cleanup
For historical reasons, 'bool' parameters must be an int, not a bool.
But there are around 600 users, so a conversion seems like useless churn.
So we use __same_type() to distinguish, and handle both cases.

commit d4cf25003a2ce55cede7f5d703121de8937b0ee5

uvesafb: improve parameter handling.
1) Now module_param(..., invbool, ...) requires a bool, and similarly
module_param(..., bool, ...) allows it, change pmi_setpal to a bool.
2) #define param_get_scroll to NULL, since it can never be called (perm
argument to module_param_named is 0).
3) Return -EINVAL from param_set_scroll if the value is bad, so it's
reported.
Note that I don't think the old fb_get_options() is required for new
drivers: the parameters automatically work as uvesafb.XXX=... anyway.
