Arvind and I have some patches on the list that fix various relocation
issues in the decompressor binary.

As far as I can tell, Arvind's patch to suppress runtime relocations
[0] addresses this exact issue.

Unfortunately, in spite of various pings and attempts to get the x86
maintainers to notice this series, it has been ignored so far. Perhaps
this is a good time to merge it for -rc1/2?
