Revision 5b11abfdb572bf9284e596dd198ac2aaf95b6616 authored by Benjamin Herrenschmidt on 08 February 2009, 14:27:21 UTC, committed by Benjamin Herrenschmidt on 10 February 2009, 03:39:08 UTC
The new legacy_mem file in sysfs is causing problems with X on machines that don't support legacy memory access. The way I initially implemented it, we would fail with -ENXIO when trying to mmap it, thus exposing to X that we do support the API but there is no legacy memory. Unfortunately, X poor error handling is causing it to fail to start when it gets this error. This implements a workaround hack that instead maps anonymous memory instead (using shmem if VM_SHARED is set, just like /dev/zero does).
