2012-03-30x86: Use -mno-avx when availableAndi Kleen
On gccs that support AVX it's a good idea to disable that too, similar to how SSE2, SSE1 etc. are already disabled. This prevents the compiler from generating AVX ever implicitely. No failure observed, just from review. [ hpa: Marking this for urgent and stable, simply because the patch will either have absolutely no effect *or* it will avoid potentially very hard to debug failures. ] Signed-off-by: Andi Kleen <ak@linux.intel.com> Link: http://lkml.kernel.org/r/1332960678-11879-1-git-send-email-andi@firstfloor.org Signed-off-by: H.

2012-02-27x32: Warn and disable rather than error if binutils too oldH. Peter Anvin
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.

2011-11-17x86: Generate system call tables and unistd_*.h from tablesH. Peter Anvin
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.

2010-09-13x86, build: Disable -fPIE when compiling with CONFIG_CC_STACKPROTECTOR=ybasile@opensource.dyc.edu
The arch/x86/Makefile uses scripts/gcc-x86_$(BITS)-has-stack-protector.sh to check if cc1 supports -fstack-protector. When -fPIE is passed to cc1, these scripts fail causing stack protection to be disabled even when it is available.

2009-09-20kbuild: use INSTALLKERNEL to select customized installkernel scriptSam Ravnborg
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: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("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.

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.
