commit 21a3c96 uses node_start/end_pfn(nid) for detection start/end
of nodes. But, it's not defined in linux/mmzone.h but defined in
/arch/???/include/mmzone.h which is included only under
CONFIG_NEED_MULTIPLE_NODES=y.
Then, we see
mm/page_cgroup.c: In function 'page_cgroup_init':
mm/page_cgroup.c:308: error: implicit declaration of function 'node_start_pfn'
mm/page_cgroup.c:309: error: implicit declaration of function 'node_end_pfn'
So, fixiing page_cgroup.c is an idea...
But node_start_pfn()/node_end_pfn() is a very generic macro and
should be implemented in the same manner for all archs.
(m32r has different implementation...)
This patch removes definitions of node_start/end_pfn() in each archs
and defines a unified one in linux/mmzone.h. It's not under
CONFIG_NEED_MULTIPLE_NODES, now.
A result of macro expansion is here (mm/page_cgroup.c)
for !NUMA
start_pfn = ((&contig_page_data)->node_start_pfn);
end_pfn = ({ pg_data_t *__pgdat = (&contig_page_data); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;});
for NUMA (x86-64)
start_pfn = ((node_data[nid])->node_start_pfn);
end_pfn = ({ pg_data_t *__pgdat = (node_data[nid]); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;});
Changelog:
- fixed to avoid using "nid" twice in node_end_pfn() macro.

When iputting the inode, We may leave the delayed nodes if they have some
delayed items that have not been dealt with. So when the inode is read again,
we must look up the relative delayed node, and use the information in it to
initialize the inode. Or we will get inconsonant inode information, it may
cause that the same directory index number is allocated again, and hit the
following oops:

SCSI defines discard alignment as the offset to the first
optimal discard. In the case of SD/MMC, that is always zero
which is the default.
SCSI defines discard granularity as a hint of a optimal
discard size. That is much better expressed by the MMC
"preferred erase size" (pref_erase) field.

The OMAP HSMMC driver uses an ocr_mask to determine the list of voltages
supported by the card. It populates this mask based on the list of
voltages supported by the regulator that supplies the voltage.
Commit 64be97822b (omap4 hsmmc: Update ocr mask for MMC2 for regulator
to use) passed a fixed ocr_mask from the OMAP4 SDP board file to limit
the voltage to 2.9-3.0 Volts, and updated the driver to use this mask
if provided, instead of using the regulator's supported voltages.
However the commit is buggy - the ocr_mask is overridden by the
regulator's capabilities anyway. Fix this.
(The bug shows up when a system-wide suspend is attempted on the OMAP4
SDP/Blaze platforms. The eMMC card comes up at 3V, but drops to 1.65V
after the system resumes).

After commit e1866b3 "PM / Runtime: Rework runtime PM handling
during driver removal" was introduced, the driver core stopped
incrementing the runtime PM usage counter of the device during
the invocation of the ->remove() callback.
This indirectly broke SDIO's runtime PM path during driver removal,
because no one calls _put_sync() anymore after ->remove() completes.
This means that the power of runtime-PM-managed SDIO cards is kept
high after their driver is removed (even if it was powered down
beforehand).
Fix that by directly calling _put_sync() when the last usage
counter is downref'ed by the SDIO bus.
