In pxelinux.asm the xchg instruction in xchg ax,ax . data_on_top: should be xchg ax,dx, I think At the end of pxe_get_cached_info routine,there is and ax,ax jnz .err It is supposed to test for AX status, but since pxenv does pushad and popad, AX doesn't contain status. In fact the other routines calling pxenv don't have this bug. pxe_unload seems to be never called; if so, also RealBaseMem is unused. According to the specification, pxe_unload_stack_pkt.reserved are 10 bytes, not 10 words

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 --

This set of patches add some support for sector size >512. Currently it fixes extlinux, MBR for GPT and ext partitions. Other code is unaffected. This set of patches has been tested on a read Dell machine running a beta firmware.

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
