2009-06-18md: raid0/linear: ensure device sizes are rounded to chunk size.NeilBrown
This is currently ensured by common code, but it is more reliable to ensure it where it is needed in personality code. All the other personalities that care already round the size to the chunk_size. raid0 and linear are the only hold-outs. Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-18md: move assignment of ->utime so that it never gets skipped.NeilBrown
Currently the assignment to utime gets skipped for 'external' metadata. So move it to the top of the function so that it always gets effected. This is of largely cosmetic interest. Nothing actually depends on ->utime being right for external arrays. "mdadm --monitor" does use it for 0.90 and 1.x arrays, but with mdadm-3.0, this is not important for external metadata. Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-18md: Push down reconstruction log message to personality code.Andre Noll
Currently, the md layer checks in analyze_sbs() if the raid level supports reconstruction (mddev->level >= 1) and if reconstruction is in progress (mddev->recovery_cp != MaxSector). Move that printk into the personality code of those raid levels that care (levels 1, 4, 5, 6, 10). Signed-off-by: Andre Noll <maan@systemlinux.org> Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-18md: merge reconfig and check_reshape methods.NeilBrown
The difference between these two methods is artificial. Both check that a pending reshape is valid, and perform any aspect of it that can be done immediately. 'reconfig' handles chunk size and layout. 'check_reshape' handles raid_disks. So make them just one method. Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-18md: remove unnecessary arguments from ->reconfig method.NeilBrown
Passing the new layout and chunksize as args is not necessary as the mddev has fields for new_check and new_layout. This is preparation for combining the check_reshape and reconfig methods Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-18md: raid5: check stripe cache is large enough in start_reshapeNeilBrown
In reshape cases that do not change the number of devices, start_reshape is called without first calling check_reshape. Currently, the check that the stripe_cache is large enough is only done in check_reshape. It should be in start_reshape too. Signed-off-by: NeilBrown <neilb@suse.de>

following the conversion to chunk_sectors, there is room for cleaning up a little. Signed-off-by: NeilBrown <neilb@suse.de>

2009-06-18md: Convert mddev->new_chunk to sectors.Andre Noll
A straight-forward conversion which gets rid of some multiplications/divisions/shifts. The patch also introduces a couple of new ones, most of which are due to conf->chunk_size still being represented in bytes. This will be cleaned up in subsequent patches.

2009-06-18md: Make mddev->chunk_size sector-based.Andre Noll
This patch renames the chunk_size field to chunk_sectors with the implied change of semantics. Since is_power_of_2(chunk_size) = is_power_of_2(chunk_sectors << 9) = is_power_of_2(chunk_sectors) these bits don't need an adjustment for the shift.

After performing an operation over the page list for a buffer retrieved by i915_gem_object_get_pages() the pages need to be returned with i915_gem_object_put_pages(). This was not being observed for the phys objects which were thus leaking references to their backing pages.

2009-06-17mfd: add PCAP driverDaniel Ribeiro
The PCAP Asic as present on EZX phones is a multi function device with voltage regulators, ADC, touch screen controller, RTC, USB transceiver, leds controller, and audio codec. It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).

2009-06-17mfd: Mark clocks_init as non-init in twl4030-core.cRakib Mullick
Impact: Fix section mismatch. clocks_init() has been called from twl4030_probe() which is a non-init function. Since probing can be done anytime so clocks_init will be called anytime too. So we mark clock_init() as non-init. LD drivers/mfd/built-in.o WARNING: drivers/mfd/built-in.o(.text+0x8dd9): Section mismatch in reference from the function twl4030_probe() to the function .init.text:clocks_init() The function twl4030_probe() references the function __init clocks_init().

It is generally agreed that it would be beneficial for u64 to be an unsigned long long on all architectures. ia64 (in common with several other 64-bit architectures) currently uses unsigned long. Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.
