git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull exception table generation updates from Ingo Molnar: "The biggest change here is to allow the build-time sorting of the exception table, to speed up booting. This is achieved by the architecture enabling BUILDTIME_EXTABLE_SORT. This option is enabled for x86 and MIPS currently. On x86 a number of fixes and changes were needed to allow build-time sorting of the exception table, in particular a relocation invariant exception table format was needed. This required the abstracting out of exception table protocol and the removal of 20 years of accumulated assumptions about the x86 exception table format. While at it, this tree also cleans up various other aspects of exception handling, such as early(er) exception handling for rdmsr_safe() et al. All in one, as the result of these changes the x86 exception code is now pretty nice and modern. As an added bonus any regressions in this code will be early and violent crashes, so if you see any of those, you'll know whom to blame!" Fix up trivial conflicts in arch/{mips,x86}/Kconfig files due to nearby modifications of other core architecture options. * 'x86-extable-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (35 commits) Revert "x86, extable: Disable presorted exception table for now" scripts/sortextable: Handle relative entries, and other cleanups x86, extable: Switch to relative exception table entries x86, extable: Disable presorted exception table for now x86, extable: Add _ASM_EXTABLE_EX() macro x86, extable: Remove open-coded exception table entries in arch/x86/ia32/ia32entry.S x86, extable: Remove open-coded exception table entries in arch/x86/include/asm/xsave.h x86, extable: Remove open-coded exception table entries in arch/x86/include/asm/kvm_host.h x86, extable: Remove the now-unused __ASM_EX_SEC macros x86, extable: Remove open-coded exception table entries in arch/x86/xen/xen-asm_32.S x86, extable: Remove open-coded exception table entries in arch/x86/um/checksum_32.S x86, extable: Remove open-coded exception table entries in arch/x86/lib/usercopy_32.c x86, extable: Remove open-coded exception table entries in arch/x86/lib/putuser.S x86, extable: Remove open-coded exception table entries in arch/x86/lib/getuser.S x86, extable: Remove open-coded exception table entries in arch/x86/lib/csum-copy_64.S x86, extable: Remove open-coded exception table entries in arch/x86/lib/copy_user_nocache_64.S x86, extable: Remove open-coded exception table entries in arch/x86/lib/copy_user_64.S x86, extable: Remove open-coded exception table entries in arch/x86/lib/checksum_32.S x86, extable: Remove open-coded exception table entries in arch/x86/kernel/test_rodata.c x86, extable: Remove open-coded exception table entries in arch/x86/kernel/entry_64.S ...

2012-05-18x86, realmode: 16-bit real-mode code support for relocs toolH. Peter Anvin1-3/+6
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.

2012-05-05kbuild: link of vmlinux moved to a scriptSam Ravnborg1-203/+12
Move the final link of vmlinux to a script to improve readability and maintainability of the code. The Makefile fragments used to link vmlinux has over the years seen far too many changes and the logic had become hard to follow. As the process by nature is serialized there was nothing gained including this in the Makefile. "um" has special link requirments - and the only way to handle this was to hard-code the linking of "um" in the script. This was better than trying to modularize it only for the benefit of "um" anyway.

When using remake, which is based on gnumake, if you invoke an example build as shown below, the build will become silent due to the top level make file incorrectly guessing that the end user wants a silent build because an argument that contained an "s" was used.
