From 0da1d4a0b9516adb2acc4841e9f6da6618f47f4e Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Fri, 8 Aug 2014 16:25:47 -0700 Subject: x86: Add "make tinyconfig" to configure the tiniest possible kernel Since commit 5d2acfc7b974bbd3858b4dd3f2cdc6362dd8843a ("kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT") in 3.15-rc1, "make allnoconfig" disables every possible config option. However, a few configuration options (CC_OPTIMIZE_FOR_SIZE, OPTIMIZE_INLINING) produce a smaller kernel when turned on, and a few choices exist (compression, highmem, allocator) for which a non-default option produces a smaller kernel. Add a "tinyconfig" option, which starts from allnoconfig and then sets these options to configure the tiniest possible kernel. This provides a better baseline for embedded systems or efforts to reduce kernel size.
