| |
virt_to_bus/bus_to_virt are long deprecated, mark them as __deprecated on i386.
Without such warnings people will never update their code and fix the errors in PPC64 builds.
And yes, some of the drivers affected are maintained.
As an example, the only usage of bus_to_virt() in the infiniband code was added in 2.6.17-rc1 (sic).
This patch increases the number of warnings shown during builds, but it seems worth including it at least in -mm for making people aware of this issue.
