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. Signed-off-by: Anton Altaparmakov <aia21@cantab.net> Cc: Chris Dearman <chris@mips.com> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: http://patchwork.linux-mips.org/patch/1084/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
