x86/mm: Pass flush_tlb_info to flush_tlb_others() etc
Rather than passing all the contents of flush_tlb_info to
flush_tlb_others(), pass a pointer to the structure directly. For
consistency, this also removes the unnecessary cpu parameter from
uv_flush_tlb_others() to make its signature match the other
*flush_tlb_others() functions.
This serves two purposes:
- It will dramatically simplify future patches that change struct
flush_tlb_info, which I'm planning to do.
- struct flush_tlb_info is an adequate description of what to do
for a local flush, too, so by reusing it we can remove duplicated
code between local and remove flushes in a future patch.
