The LM63 and compatible devices have a lookup table to control the fan
speed automatically. Expose it in sysfs. Values are cached for 5
seconds, independently of the other register values to avoid slowing
down "sensors". We might make the table values writable in the future.Signed-off-by: Jean Delvare

This patch fixed the inconsistent max1111 sysfs interface as pointed
out by Jean Delvare:It was pointed to me that the max1111 driver doesn't implement the
standard sysfs interface for hwmon drivers (as described in
Documentation/hwmon/sysfs-interface). It exports files adc[0-3]_in,
which
aren't part of the standard interface. Presumably these should be
renamed to in[0-3]_input. Renaming them is probably not sufficient
though, as I see no scaling done in the driver. As the MAX1111 chip has
a documented full scale of 2.048V, I take it that the LSB of the ADC
has a weight of 8 mV. Exporting raw register values to user-space is
not OK.Reported-by: Jean Delvare

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Acked-by: Mauro Carvalho Chehab
Signed-off-by: Rusty Russell -
For historical reasons, we allow module_param(bool) to take an int (or
an unsigned int). That's going away.A few drivers really want an int: they set it to -1 and a parameter
will set it to 0 or 1. This sucks: reading them from sysfs will give
'Y' for both -1 and 1, but if we change it to an int, then the users
might be broken (if they did "param" instead of "param=1").Use a new 'bint' parser for them.
(ntfs has a different problem: it needs an int for debug_msgs because
it's also exposed via sysctl.)Cc: Steve Glendinning

Several fields in struct cpuinfo_x86 were not defined for the
!SMP case, likely to save space. However, those fields still
have some meaning for UP, and keeping them allows some #ifdef
removal from other files. The additional size of the UP kernel
from this change is not significant enough to worry about
keeping up the distinction:text data bss dec hex filename

4737444 506459 972040 6215943 5ed907 vmlinux.o.afterfor a difference of 276 bytes for an example UP config.
If someone wants those 276 bytes back badly then it should
be implemented in a cleaner way.Signed-off-by: Kevin Winchester
