* Don't set the INITRD_COMPRESS environment variable automaticallyLinus Torvalds2013-12-211-1/+3
| | | | | | | | | | | | | | | | | | | Commit 1bf49dd4be0b ("./Makefile: export initial ramdisk compression config option") started setting the INITRD_COMPRESS environment variable depending on which decompression models the kernel had available. That is completely broken. For example, we by default have CONFIG_RD_LZ4 enabled, and are able to decompress such an initrd, but the user tools to *create* such an initrd may not be availble. So trying to tell dracut to generate an lz4-compressed image just because we can decode such an image is completely inappropriate.

* fix build with make 3.80Jan Beulich2013-12-191-13/+7
| | | | | | | | | | | | | | | | | According to Documentation/Changes, make 3.80 is still being supported for building the kernel, hence make files must not make (unconditional) use of features introduced only in newer versions. Commit 1bf49dd4be0b ("./Makefile: export initial ramdisk compression config option") however introduced "else ifeq" constructs which make 3.80 doesn't understand. Replace the logic there with more conventional (in the kernel build infrastructure) list constructs (except that the list here is intentionally limited to exactly one element).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building the kernel in a shell which defines GREP_OPTIONS so that grep behavior is modified, we can break the generation of the syscalls table like so: __SYSCALL_COMMON(^[[01;31m^[[K0^[[m^[[K, sys_read, sys_read) __SYSCALL_COMMON(^[[01;31m^[[K1^[[m^[[K, sys_write, sys_write) __SYSCALL_COMMON(^[[01;31m^[[K1^[[m^[[K0, sys_mprotect, sys_mprotect) ... This is just the initial breakage, later we barf when generating modules. In this case, GREP_OPTIONS contains "--color=always" which adds the shell colors markup and completely fudges the headers under ...generated/asm/. Fix that by unexporting the GREP_OPTIONS variable for the whole kernel build as we tend to use grep at a bunch of places.

* | ./Makefile: export initial ramdisk compression config optionP J P2013-11-131-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make menuconfig allows one to choose compression format of an initial ramdisk image. But this choice does not result in duly compressed ramdisk image. Because - $ make install - does not pass on the selected compression choice to the dracut(8) tool, which creates the initramfs file. dracut(8) generates the image with the default compression, ie. gzip(1). This patch exports the selected compression option to a sub-shell environment, so that it could be used by dracut(8) tool to generate appropriately compressed initramfs images. There isn't a straightforward way to pass on options to dracut(8) via positional parameters. Because it is indirectly invoked at the end of a $ make install sequence. # make install -> arch/$arch/boot/Makefile -> arch/$arch/boot/install.sh -> /sbing/installkernel ... -> /sbin/new-kernel-pkg ... -> /sbin/dracut ...

| | | | | | | | | | | | | | | | | | | | This reverts commit d2aae8477cd00325bb7c7c7e95be488088900c48. It is completely and utterly broken. Module install should not build any files, and adding broken dependencies to "help" it build files is complete and utter sh*t. The kernel should not be built by root, and "make install" and "make module_install" (that for obvious reasons need to be run as root) absolutely must not build any files. They should only ever copy the already-built files over. So having dependencies for the install targets is wrong, wrong, wrong. If you try to install a kernel without building it first, you *should* get errors. The build system shouldn't try to help root build the files.

But Al Viro broke this in "consolidate cond_syscall and SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to do so. Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to prefix it so something. So various places define helpers which are defined to nothing if CONFIG_SYMBOL_PREFIX isn't set: 1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX. 2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym) 3) include/linux/export.h defines MODULE_SYMBOL_PREFIX. 4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7) 5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym) 6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX 7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version for pasting. (arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too). Let's solve this properly: 1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX. 2) Make linux/export.h usable from asm. 3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR(). 4) Make everyone use them.

This is the default when building allyesconfig, which turns on CONFIG_CC_OPTIMIZE_FOR_SIZE. In order to avoid getting a lot of patches that initialize such variables and accidentally hide real errors along the way, let's just turn off this warning on the respective gcc versions when building with size optimizations. The -Wmaybe-uninitialized option was introduced in the same gcc version (4.7) that is now causing the false positives, so there is no effect on older compilers. A side effect is that when building with CONFIG_CC_OPTIMIZE_FOR_SIZE, we might now see /fewer/ warnings about possibly uninitialized warnings than with -O2, but that is still much better than seeing warnings known to be bogus.
