I ran 16KB page size kernel on IA64 with your page_buf.c patch.

[root@luna /]# mkfs -t xfs -b size=16384 -f /dev/sdc1
meta-data=/dev/sdc1              isize=256    agcount=8, agsize=8033 blks
data     =                       bsize=16384  blocks=64258, imaxpct=25
         =                       sunit=0      swidth=0 blks, unwritten=0
naming   =version 2              bsize=16384 
log      =internal log           bsize=16384  blocks=1000
realtime =none                   extsz=65536  blocks=0, rtextents=0

When I type mount command, I trapped at xlog_brread and xfsbdstrat. 

[root@luna /]# mount -t xfs /dev/sdc1 /mnt/xfs
