similar to: [patch rfc wip] first cut of ELF bzImage

OK, here's another go-around. This patch leaves the bzImage itself unmodified, but it changes the payload into an ELF file. That is, the 32-bit decompression/relocation+compressed kernel is now a properly formed ELF file. One thing that fell out of this is that code32_start end up being a pointer to the ELF header rather than an entrypoint. Rather than reproducing Vivek's (?) hack of

This series updates the boot protocol to 2.07 and uses it to implement paravirtual booting. This allows the bootloader to tell the kernel what kind of hardware/pseudo-hardware environment it's coming up under, and the kernel can use the appropriate boot sequence code. Specifically: - Update the boot protocol to 2.07, which adds fields to specify the hardware subarchitecture and some

The ELF relocation record format is different for N64 which many Mips 64 ABIs use than for O64 which many if not all other target ABIs use. The question I have is whether to treat N64 as a valid generic variant or should it be treated as target specific? My contention is that it should be treated as an alternative generic format handled recognized and handled in the ELF class objects above the

Sri and I have been working on this over the past few months, and we've made some good progress that we'd like to share and get feedback on. Our work is based on the 'experimental-relr' prototype from Cary that is available at 'users/ccoutant/experimental-relr' branch in the binutils repository [1], and was described earlier in this thread:

Hello All, In ARM embedded applications, there are some compilers that support useful function and variable attributes that help the compiler communicate information about symbols to downstream object consumers (i.e. linkers). One such attribute is the "location" attribute. This attribute can be applied to a global or local static data object or a function to indicate to the linker

There are a bunch of issues with defining elf notes using assembler macros, as described here: http://marc.theaimsgroup.com/?l=linux-kernel&m=115633393226158&w=2 Therefore I replaced it with a pre-processor macro. This is a new patch, it should fit into the series anywhere after the -mm patch. It's been submitted to Andrew M so hopefully it'll get picked up for next -mm.

From: Mukesh Rathor <mukesh.rathor@oracle.com> Use .ascii and .asciz to define xen feature string. Note, the PVH string must be in a single line (not multiple lines with \) to keep the assembler from putting null char after each string before \.

Hi, I've come across some problems with the assembly version of the ELFNOTE macro currently in -mm. (in x86-put-note-sections-into-a-pt_note-segment-in-vmlinux.patch) The first is that older gas does not support :varargs in .macro definitions (in my testing 2.17 does while 2.15 does not, I don't know when it became supported). The Changes file says binutils >= 2.12 so I think we need

With a suitably recent xen the __xen_guest string is no longer required so remove it. See the caveat in 0/5 though!

A simple combination of delta-encoding and run_length-encoding is one of the first schemes we experimented with (32-bit entries with 24-bit 'delta' and an 8-bit 'count'). This gave really good results, but as Sri mentions, we observed several cases where the relative relocations were not on consecutive offsets. There were common cases where the relocations applied to alternate
