2010-08-11param: update drivers/char/ipmi/ipmi_watchdog.c to new schemeRusty Russell
This is one of the most interesting users of module parameters in the tree, so weaning it off the old-style non-const module_param_call scheme is a useful exercise. I was confused by set_param_int/get_param_int (vs. the normal param_set_int and param_get_int), so I renamed set_param_int to set_param_timeout, and re-used param_get_int directly instead of get_param_int. I also implemented param_check_wdog_ifnum and param_check_timeout, so now the ifnum_to_use and timeout/pretimeout parameters can just use plain module_param().

2010-08-11param: remove unnecessary writable charpRusty Russell
sysfs-writable charp arguments need to be locked against modification (since the old ones may be kfreed underneath us). String arguments are much simpler, so use them for small strings (eg. IFNAMSIZ). lkdtm only uses the parameters at module initialization time, so there's not much point making them writable.

2010-08-11param: locking for kernel parametersRusty Russell
There may be cases (most obviously, sysfs-writable charp parameters) where a module needs to prevent sysfs access to parameters. Rather than express this in terms of a big lock, the functions are expressed in terms of what they protect against. This is clearer, esp. if the implementation changes to a module-level or even param-level lock.

Instead of using a "I kmalloced this" flag, we keep track of the kmalloced strings and use that list to check if we need to kfree (in practice, the list is very short).

2010-08-11param: use ops in struct kernel_param, rather than get and set fns directlyRusty Russell
This is more kernel-ish, saves some space, and also allows us to expand the ops without breaking all the callers who are happy for the new members to be NULL. The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb.

Ramp Up Delay. max8998_set_voltage should provide delay for BUCK1/2 if ENRAMP is on. It reads RAMP value from ONOFF4 register to determine RAMP delay length. However, when max8998_set_voltage's new voltage is lower than the previous, we don't care because it does not deteriorate the stability.
