This fixes booting kernels with boot2 (except for loss of the features provided by loader) and is suitable for MFC. Contrary to the old comments, most loaders don't clear the bss. biosboot lost clearing of the bss in a code crunch in 1997, and boot2 never did it. kan didn't notice the problem with gcc-3.3 putting variables that are initialized to 0 in the bss until after committing gcc-3.3 because he was already using essentially this patch. Before gcc-3.3, only the non-critical `bootdev' variable was clobbered by clearing the bss. MFC after: 3 days |
