From 9a9e0d685553af76cb6ae2af93cca4913e7fcd47 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 15 Mar 2008 11:53:32 -0700 Subject: ACPI: Remove ACPI_CUSTOM_DSDT_INITRD option This essentially reverts commit 71fc47a9adf8ee89e5c96a47222915c5485ac437 ("ACPI: basic initramfs DSDT override support"), because the code simply isn't ready. It did ugly things to the init sequence to populate the rootfs image early, but that just ended up showing other problems with the whole approach. The fact is, the VFS layer simply isn't initialized this early, and the relevant ACPI code should either run much later, or this shouldn't be done at all. For 2.6.25, we'll just pick the latter option. We can revisit this concept later if necessary.
