Btw, some more comments on the 32bit compat code in drm:
- instead of set_fs & co and passing kernel addresses to drm_ioctl
please use compat_alloc_user_space()
- this:
+ifeq ($(CONFIG_COMPAT),y)
+drm-objs += drm_ioc32.o
+radeon-objs += radeon_ioc32.o
+endif
should be written as
drm-$(CONFIG_COMPAT) += drm_ioc32.o
radeon-$(CONFIG_COMPAT) += radeon_ioc32.o
and everything else should use foo-y instead of foo-objs
- the magic CONFIG_COMPAT changes for SHM handles should only be done when
a module is set. CONFIG_COMPAT is set for mostly 64bit systems that can
run 32bit code and drm shouldn't behave differently just because we can
run 32bit code.
