If X32 is enabled in .config, but the binutils can't build it, issue a warning and disable the feature rather than erroring out. In order to support this, have CONFIG_X86_X32 be the option set in Kconfig, and CONFIG_X86_X32_ABI be the option set by the Makefile when it is enabled and binutils has been found to be functional.

Generate system call tables and unistd_*.h automatically from the tables in arch/x86/syscalls. All other information, like NR_syscalls, is auto-generated, some of which is in asm-offsets_*.c. This allows us to keep all the system call information in one place, and allows for kernel space and user space to see different information; this is currently used for the ia32 system call numbers when building the 64-bit kernel, but will be used by the x32 ABI in the near future. This also removes some gratuitious differences between i386, x86-64 and ia32; in particular, now all system call tables are generated with the same mechanism. Cc: H. J.

The arch/x86/Makefile uses scripts/gcc-x86_$(BITS)-has-stack-protector.sh to check if cc1 supports -fstack-protector.

Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

General description: kmemcheck is a patch to the linux kernel that detects use of uninitialized memory. It does this by trapping every read and write to memory that was allocated dynamically (e.g. using kmalloc()). If a memory address is read that has not previously been written to, a message is printed to the kernel log. Thanks to Andi Kleen for the set_memory_4k() solution. Andrew Morton suggested documenting the shadow member of struct page.

If the user selects the stack-protector config option, but does not have a gcc that has the right bits enabled (for example because it isn't build with a glibc that supports TLS, as is common for cross-compilers, but also because it may be too old), then the runtime test fails right now. This patch adds a warning message for this scenario. This warning accomplishes two goals 1) the user is informed that the security option he selective isn't available 2) the user is suggested to turn of the CONFIG option that won't work for him, and would make the runtime test fail anyway.

Unify the 32 and 64 bit specific Makefiles. The unification was simplest to do in one step although the readability of the patch suffers a bit from this. Noteworthy remarks on the unification: - The 64 bit cpu stuff should be moved to Makefile_32.cpu but I did not feel confident doing it due to subtle differences - The use of cflags-y were abandoned since we have seen one bug where we did wrong due to missing assignment to KBUILD_CFLAGS. The cc-option marcro uses KBUILD_CFLAGS. - The "No need to remake" line are deleted. It caused "make -B" to fail - For 64 bit the sub architecture stuff is not used. - The way head64.o is specified could be nicer - but it awaits the introduction of head32.o (which seems like a win to introduce for readability) - Patch is checkpatch clean Patch is tested by doing a defconfig build for i386 and x86_64 and in both cases monitoring that only relevant files were recompiled when applying the patch.
