Use .fixup instead of .text.fixup on __kvm_handle_fault_on_reboot

[oops. sent it to the old kvm-devel list. sending to the right list, now]

vmlinux.lds expects the fixup code to be on a section named .fixup. The .text.fixup section is not mentioned on vmlinux.lds, and is included on the resulting vmlinux (just after .text) only because of ld heuristics on placing orphan sections.

However, placing .text.fixup outside .text breaks the definition of _etext, making it exclude the .text.fixup contents. That makes .text.fixup be ignored by the kernel initialization code that needs to know about section locations, such as the code setting page protection bits.
