Hi Andi, Four patches: - clean up asm/bugs.h, by moving all the C code into its own C file - split identify_cpu() into boot and secondary variants, so that boot-time setup functions can be marked __init - repost of the COMPAT_VDSO patches with a bit more robustness from unknown DT_tags, and functions marked __init, since all this is boot-time only setup. Thanks, J --

Has anyone ever come across general-purpose tools for modifying shared libraries? What I want to do is to edit the list of "needed" shared libraries to correct the common mistakes that developers make in creating shared objects with large lists of shared libraries. Specifically, I want to modify linux-flashplugin6/libflashplayer.so to remove all of the idiotic references to shared

Hi Andi, Here's a couple of patches to fix up COMPAT_VDSO: The first is a straightforward implementation of Jan's original idea of relocating the VDSO to match its mapped location. Unlike Jan and Zach's version, I changed it to relocate based on the phdrs rather than the sections; the result is pleasantly compact. The second patch takes advantage of the fact that all the

Create a configurable hole in the linear address space at the top of memory. A more advanced interface is needed to negotiate how much space the hypervisor is allowed to steal, but in the end, it seems most likely that a fixed constant size will be chosen for the compiled kernel, potentially propagated to an information page used by paravirtual initialization to determine interface compatibility.

Hi, These patches contain support for some features that are already in Syslinux 4 but weren't working properly on the elflink branch. It's another step closer to feature parity with Syslinux 4. Having to jump through the comboot API for localboot support is less than ideal and I'll eventually fix that, probably when we move a big chunk of code from asm to C. Also, there's a

This series: 1. Updates the boot protocol to version 2.07 2. Clean up the existing build process, to get rid of tools/build and make the linker do more heavy lifting 3. Make the bzImage payload an ELF file. The bootloader can extract this as a naked ELF file by skipping over boot_params.setup_sects worth of 16-bit setup code. 4. Update the boot_params to 2.07, and update the
