MIPS: Fix __vmalloc() etc. on MIPS for non-GPL modules
Commit b3594a089f1c17ff919f8f78505c3f20e1f6f8ce (lmo) rsp.
351336929ccf222ae38ff0cb7a8dd5fd5c6236a0 (kernel.org) break non-GPL modules
that use __vmalloc() or any of the vmap(), vm_map_ram(), etc functions on
MIPS.
All those functions are EXPORT_SYMBOL() so are meant to be allowed to be
used by non-GPL kernel modules. These calls all take page protection as
an argument which is normally a constant like PAGE_KERNEL.
This commit causes all protection constants like PAGE_KERNEL to not be
constants and instead to contain the GPL-only symbol _page_cachable_default.
This means that all calls to __vmalloc(), vmap(), etc, cause non-GPL
modules to fail to link with the complaint that they are trying to use the
GPL-only symbol _page_cachable_default...
Change EXPORT_SYMBOL_GPL(_page_cachable_default) to EXPORT_SYMBOL() for
non-GPL modules that call __vmalloc(), vmap(), vm_map_ram() etc.
