Jim Kukunas 2aa4ee2a88 lib/raid6: fix sparse warnings in recovery functions
Make the recovery functions static to fix the following sparse warnings:

lib/raid6/recov.c:25:6: warning: symbol 'raid6_2data_recov_intx1' was
not declared. Should it be static?
lib/raid6/recov.c:69:6: warning: symbol 'raid6_datap_recov_intx1' was
not declared. Should it be static?
lib/raid6/recov_ssse3.c:22:6: warning: symbol 'raid6_2data_recov_ssse3'
was not declared. Should it be static?
lib/raid6/recov_ssse3.c:197:6: warning: symbol 'raid6_datap_recov_ssse3'
was not declared. Should it be static?

Jim Kukunas 96e67703e7 lib/raid6: cleanup gen_syndrome function selection
Reorders functions in raid6_algos as well as the preference check
to reduce the number of functions tested on initialization.

Also, creates symmetry between choosing the gen_syndrome functions
and choosing the recovery functions.

Paul Gortmaker daaa5f7cbe md: Add in export.h for files using EXPORT_SYMBOL
These files were getting the defines for EXPORT_SYMBOL because
device.h was including module.h.  But we are going to put an
end to that.  So add the proper export.h include now.

Paul Gortmaker 056075c764 md: Add module.h to all files using it implicitly
A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in md dir
are actually calling out for <module.h> explicitly in advance.
