Subject: 2.6.23-rc6-mm1: Build failure on ppc64 drivers/ata/pata_scc.c

PPC64 building allmodconfig fails to compile drivers/ata/pata_scc.c . It
doesn't show up on other arches because this driver is specific to the
architecture.

drivers/ata/pata_scc.c: In function `scc_bmdma_status':
drivers/ata/pata_scc.c:734: error: structure has no member named `active_tag'
drivers/ata/pata_scc.c: In function `scc_pata_prereset':
drivers/ata/pata_scc.c:866: warning: passing arg 1 of `ata_std_prereset' from incompatible pointer type
drivers/ata/pata_scc.c: In function `scc_error_handler':
drivers/ata/pata_scc.c:908: warning: passing arg 2 of `ata_bmdma_drive_eh' from incompatible pointer type
drivers/ata/pata_scc.c:908: warning: passing arg 3 of `ata_bmdma_drive_eh' from incompatible pointer type
drivers/ata/pata_scc.c:908: warning: passing arg 5 of `ata_bmdma_drive_eh' from incompatible pointer type
make[2]: *** [drivers/ata/pata_scc.o] Error 1
make[1]: *** [drivers/ata] Error 2
make: *** [drivers] Error 2

The problem seems to be in git-libata-all.patch but based on similar
changes in this patch, the following patch should be the fix.
