Seems, this may be useful.

bio_buffer variable at my book has address 0x5a6b4 and PTOV(V86_IO_BUFFER)
equals to 0xffffe000.

loader's smap gives also:

SMAP type=01 base=0000000000000000 len=000000000009dc00
SMAP type=02 base=00000000ffb00000 len=0000000000500000

So bio_buffer resides in usable memory block (type=01) and PTOV(V86_IO_BUFFER)
is in reserved (type=02) memory block.
