mm: include swap.h in swapops.h
swapops.h uses MAX_SWAPFILES_SHIFT, SWP_MIGRATION_READ and SWP_PTE_MARKER,
all of which swap.h defines, but does not include swap.h. It compiles only
where the translation unit pulled swap.h in first. leafops.h includes
swapops.h on the line above swap.h, so a file whose include list reaches
leafops.h before swap.h gets:
In file included from include/linux/leafops.h:11:
include/linux/swapops.h:88:21: error: use of undeclared
identifier 'MAX_SWAPFILES_SHIFT'
A header that uses a definition has to include the header that provides it.
