This is achieved by writing to the sysfs tunables "probe" during allocation and "release" during deallocation. At the sametime, the userspace can independently online/offline the CPUs of the system using the sysfs tunable "online". It is quite possible that when a userspace tool offlines a CPU for the purpose of deallocation and is in the process of updating the device tree, some other userspace tool could bring the CPU back online by writing to the "online" sysfs tunable thereby causing the deallocate process to fail. The solution to this is to serialize writes to the "probe/release" sysfs tunable with the writes to the "online" sysfs tunable. This patch employs a mutex to provide this serialization, which is a no-op on all architectures except PPC_PSERIES Signed-off-by: Gautham R Shenoy <ego@in.ibm.com> Acked-by: Vaidyanathan Srinivasan <svaidy@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

There are no changes to any of the C code from v2 of the patch. In order to support kernel DLPAR of CPU resources we need to provide an interface to add (probe) and remove (release) the resource from the system. This patch Creates new generic probe and release sysfs files to facilitate cpu probe/release. The probe/release interface provides for allowing each arch to supply their own routines for implementing the backend of adding and removing cpus to/from the system. This also creates the powerpc specific stubs to handle the arch callouts from writes to the sysfs files. The creation and use of these files is regulated by the CONFIG_ARCH_CPU_PROBE_RELEASE option so that only architectures that need the capability will have the files created.

On my PowerBook G4, this results in the fans going to full speed at low temperature and shutting off at high temperature because the pwm invert bit is supposed to be set. Therefore, record the pwm invert bit at driver load time, and write the bit into the fan behavior control register. This restores correct behavior on my PBG4 and should work around the bit being set to the wrong value after suspend/resume (which is what the original patch was trying to fix). It also fixes a minor omission where the pwm invert bit correction is NOT performed when switching into automatic mode. Signed-off-by: Darrick J.

In addition it's ugly and could be done better. This reworks the interface between the mediabay and the rest of the world so that: - Any macio_driver can now have a mediabay_event callback which will be called when that driver sits on a mediabay and it's been either plugged or unplugged. The device type is passed as an argument. We can now move all the IDE cruft into the IDE driver itself - A check_media_bay() function can be used to take a peek at the type of device currently in the bay if any, a cleaner variant of the previous function with the same name. - A pair of lock/unlock functions are exposed to allow the IDE driver to block the hotplug callbacks during the initial setup and probing of the bay in order to avoid nasty race conditions. - The mediabay code no longer needs to spin on the status register of the IDE interface when it detects an IDE device, this is done just fine by the IDE code itself Overall, less code, simpler, and allows for another driver than our old drivers/ide based one.

| * | | | | macintosh: Remove BKL from nvram driverThomas Gleixner2009-11-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop the bkl from nvram_llseek() as it obviously protects nothing. The file offset is safe in essence. The ioctl can be converted to unlocked_ioctl because it just calls pmac_get_partition() which reads a value from an array which was initialized at early boot time. No need for serialization.

| * | | | | spi_mpc8xxx: Add support for QE DMA mode and CPM1/CPM2 chipsAnton Vorontsov2009-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds QE buffer descriptors mode support for the spi_mpc8xxx driver, and as a side effect we now support CPM1 and CPM2 SPI controllers. That means that today we support almost all MPC SPI controllers: - MPC834x-style controllers (support PIO mode only); - CPM1 and CPM2 controllers (support DMA mode only); - QE SPI controllers in CPU mode (PIO mode with shift quirks); - QE SPI controllers in buffer descriptors (DMA) mode; The only controller we don't currently support is a newer eSPI (with a dedicated chip selects and a bit different registers map).

Also introduce mpc8xxx_spi_strmode() and print current SPI mode.
