2014-04-14x86/build: Supress "Nothing to be done for ..." messagesMasahiro Yamada
When we build an already built kernel again, arch/x86/syscalls/Makefile and arch/x86/tools/Makefile emits "Nothing to be done for ..." messages. Here is the command log: $ make defconfig [ snip ] $ make [ snip ] $ make make[1]: Nothing to be done for `all'. <----- make[1]: Nothing to be done for `relocs'. <----- CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h Besides not emitting those, "all" and "relocs" should be added to PHONY as well.

2013-04-16x86, relocs: Build separate 32/64-bit toolsKees Cook
Since the ELF structures and access macros change size based on 32 vs 64 bits, build a separate 32-bit relocs tool (for handling realmode and 32-bit relocations), and a 64-bit relocs tool (for handling 64-bit kernel relocations).

2012-10-02UAPI: x86: Fix the test_get_len toolDavid Howells
Fix the x86 test_get_len tool to have the right include paths in the right order (it includes a non-exported kernel header directly), otherwise errors like the following occur: /data/fs/linux-2.6-hdr/include/linux/types.h:18:26: error: conflicting types for 'fd_set' /usr/include/sys/select.h:78:5: note: previous declaration of 'fd_set' was here and /data/fs/linux-2.6-hdr/include/linux/string.h:42:12: error: expected identifier or '(' before '__extension__' Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Paul E.

2012-05-18x86, realmode: 16-bit real-mode code support for relocs toolH. Peter Anvin
A new option is added to the relocs tool called '--realmode'. This option causes the generation of 16-bit segment relocations and 32-bit linear relocations for the real-mode code. When the real-mode code is moved to the low-memory during kernel initialization, these relocation entries can be used to relocate the code properly. In the assembly code 16-bit segment relocations must be relative to the 'real_mode_seg' absolute symbol. Linear relocations must be relative to a symbol prefixed with 'pa_'. 16-bit segment relocation is used to load cs:ip in 16-bit code. Linear relocations are used in the 32-bit code for relocatable data references. They are declared in the linker script of the real-mode code. The relocs tool is moved to arch/x86/tools/relocs.c, and added new target archscripts that can be used to build scripts needed building an architecture. be compiled before building the arch/x86 tree. [ hpa: accelerating this because it detects invalid absolute relocations, a serious bug in binutils 2.22.52.0.x which currently produces bad kernels. ] Signed-off-by: H.

2011-11-10x86, perf: Add a build-time sanity test to the x86 decoderMasami Hiramatsu
Add a sanity test of x86 insn decoder against a stream of randomly generated input, at build time. This test is also able to reproduce any bug that might trigger by allowing the passing of random-seed and iteration-number to the test, or by passing input which has invalid byte code. Changes in V2: - Code cleanup. - Show how to reproduce the error by insn_sanity test.

Add a user-space selftest of x86 instruction decoder at kernel build time. When CONFIG_X86_DECODER_SELFTEST=y, Kbuild builds a test harness of x86 instruction decoder and performs it after building vmlinux. The test compares the results of objdump and x86 instruction decoder code and check there are no differences.
