Hi Tejun,
After merging the libata tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
In file included from drivers/ata/libata-pmp.c:14:0:
drivers/ata/libata.h:136:1: error: unknown type name 'acpi_handle'
static inline acpi_handle ata_dev_acpi_handle(struct ata_device *dev) { return NULL; }
^
And several others.
Caused by commit f1bc1e4c44b1 ("ata: acpi: rework the ata acpi bind
support"). All the world does not have the ACPI include files
included via some other path ... nor wants them, I suspect.
I have used the libata tree from next-20130822 for today.
P.S. drivers/ata/libata.h seems to assume that a lot of other stuff is
included that it does not include explicitly ...

Sorry for the trouble, my bad.
Does the below patch fix the problem?
From: Aaron Lu <[email protected]>
Subject: [PATCH] ata: acpi: Remove ata_dev_acpi_handle stub in libata.h
The ata_dev_acpi_handle is defined in libata-acpi.c and the only
external user is libata-zpodd.c, which is built when CONFIG_ATA_ACPI
is set, so there is no need to make an empty stub function for
!CONFIG_ATA_ACPI case in libata.h. It also causes compile errors due to
acpi_handle is not defined when !CONFIG_ACPI. This patch fixes this
problem by removing the empty stub.

Yeap, tested and works. Applied to libata/for-3.12. Thanks.
Stephen, sorry about the trouble.
