Do a couple things here: - Split the mega-patches into individual patches. Should help with rebasing. - Make all patches 'git am' acceptable. There should be no functional or actual code differences from before

Subject: [PATCH] acpi: Ignore acpi_rsdp kernel parameter when module loading
|
|
is restricted
|
|
|
|
This option allows userspace to pass the RSDP address to the kernel, which
|
|
makes it possible for a user to circumvent any restrictions imposed on
|
|
loading modules. Disable it in that case.
