This should be fixed now. Just pushed out with commit 
95b08679963c78ce0d675224a6efdb5169f2bf75 ("x86_64: Add missing mask 
operation to vdso").

This *seems* to be a VIA bug. Regardless, it should be fixed by commit 
a534b679180025aa324ebd63c05516e478551cfd ("x86_64: Remove CLFLUSH in 
text_poke()").

This needs to be re-tested (was it the BIOS register overwriting, 
perhaps?).

This should probably be dropped. I don't think we have any new reports on 
it, and nobody else ever saw it.

This should be fixed by commit 980abe215b861891c39aba0936817c46f372143b 
("UML: Fix ELF_CORE_COPY_REGS build botch").
