This is a note to let you know that I have just added a patch titled turbostat: Don't put unprocessed uapi headers in the include path to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From fd4d235dd2086b0fd035b777edd5f22cfc584421 Mon Sep 17 00:00:00 2001 From: Josh Triplett <josh@joshtriplett.org> Date: Tue, 20 Aug 2013 17:20:12 -0700 Subject: turbostat: Don't put unprocessed uapi headers in the include path commit b731f3119de57144e16c19fd593b8daeb637843e upstream. turbostat's Makefile puts arch/x86/include/uapi/ in the include path, so that it can include <asm/msr.h> from it. It isn't in general safe to include even uapi headers directly from the kernel tree without processing them through scripts/headers_install.sh, but asm/msr.h happens to work. However, that include path can break with some versions of system headers, by overriding some system headers with the unprocessed versions directly from the kernel source. For instance: In file included from /build/x86-generic/usr/include/bits/sigcontext.h:28:0, from /build/x86-generic/usr/include/signal.h:339, from /build/x86-generic/usr/include/sys/wait.h:31, from turbostat.c:27: ../../../../arch/x86/include/uapi/asm/sigcontext.h:4:28: fatal error: linux/compiler.h: No such file or directory This occurs because the system bits/sigcontext.h on that build system includes <asm/sigcontext.h>, and asm/sigcontext.h in the kernel source includes <linux/compiler.h>, which scripts/headers_install.sh would have filtered out. Since turbostat really only wants a single header, just include that one header rather than putting an entire directory of kernel headers on the include path. In the process, switch from msr.h to msr-index.h, since turbostat just wants the MSR numbers.
