From: Jeff Garzik Date: Mon, 14 Nov 2005 00:06:25 +0000 (-0800) Subject: [PATCH] move pm_register/etc. to CONFIG_PM_LEGACY, pm_legacy.h X-Git-Tag: v2.6.15-rc2~207 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bca73e4bf8563d83f7856164caa44d5f42e44cca;p=linux-2.6 [PATCH] move pm_register/etc. to CONFIG_PM_LEGACY, pm_legacy.h Since few people need the support anymore, this moves the legacy pm_xxx functions to CONFIG_PM_LEGACY, and include/linux/pm_legacy.h.
