2008-04-26x86, boot: add linked list of struct setup_dataHuang, Ying
This patch adds a field of 64-bit physical pointer to NULL terminated single linked list of struct setup_data to real-mode kernel header. This is used as a more extensible boot parameters passing mechanism.

2008-04-26x86: add optimized inliningIngo Molnar
add CONFIG_OPTIMIZE_INLINING=y. allow gcc to optimize the kernel image's size by uninlining functions that have been marked 'inline'. Previously gcc was forced by Linux to always-inline these functions via a gcc attribute: #define inline inline __attribute__((always_inline)) Especially when the user has already selected CONFIG_OPTIMIZE_FOR_SIZE=y this can make a huge difference in kernel image size (using a standard Fedora .config): text data bss dec hex filename 5613924 562708 3854336 10030968 990f78 vmlinux.before 5486689 562708 3854336 9903733 971e75 vmlinux.after that's a 2.3% text size reduction (!).
