[merged] init-mainc-return-1-from-handled-__setup-functions.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: init/main.c: return 1 from handled __setup() functions
has been removed from the -mm tree.  Its filename was
     init-mainc-return-1-from-handled-__setup-functions.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Randy Dunlap <rdunlap@infradead.org>
Subject: init/main.c: return 1 from handled __setup() functions

initcall_blacklist() should return 1 to indicate that it handled its
cmdline arguments.

set_debug_rodata() should return 1 to indicate that it handled its cmdline
arguments.  Print a warning if the option string is invalid.

This prevents these strings from being added to the 'init' program's
environment as they are not init arguments/parameters.
