Merge git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild-next
* git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild-next: (30 commits) Use macros for .data.page_aligned section. Use macros for .bss.page_aligned section. Use new __init_task_data macro in arch init_task.c files. kbuild: Don't define ALIGN and ENTRY when preprocessing linker scripts. arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0 kbuild: add static to prototypes kbuild: fail build if recordmcount.pl fails kbuild: set -fconserve-stack option for gcc 4.5 kbuild: echo the record_mcount command gconfig: disable "typeahead find" search in treeviews kbuild: fix cc1 options check to ensure we do not use -fPIC when compiling checkincludes.pl: add option to remove duplicates in place markup_oops: use modinfo to avoid confusion with underscored module names checkincludes.pl: provide usage helper checkincludes.pl: close file as soon as we're done with it ctags: usability fix kernel hacking: move STRIP_ASM_SYMS from General gitignore usr/initramfs_data.cpio.bz2 and usr/initramfs_data.cpio.lzma kbuild: Check if linker supports the -X option kbuild: introduce ld-option ... Fix trivial conflict in scripts/basic/fixdep.c

INSTALL_PATH specifies where to place the updated kernel and system map
images. Default is /boot, but you can set it to other values.
+INSTALLKERNEL
+--------------------------------------------------
+Install script called when using "make install".
+The default name is "installkernel".
+
+The script will be called with the following arguments:
+ $1 - kernel version
+ $2 - kernel image file
+ $3 - kernel map file
+ $4 - default install path (use root directory if blank)
+
+The implmentation of "make install" is architecture specific
+and it may differ from the above.
+
+INSTALLKERNEL is provided to enable the possibility to
+specify a custom installer when cross compiling a kernel.
