ARM errata 798181 is applicable for OMAP5 based devices. So enable the same in the build. Errata extract and workaround information is as below. On Cortex-A15 (r0p0..r3p2) the TLBI*IS/DSB operations are not adequately shooting down all use of the old entries. The ARM_ERRATA_798181 option enables the Linux kernel workaround for this erratum which sends an IPI to the CPUs that are running the same ASID as the one being invalidated.

On platforms such as Cortex-A15 based OMAP5, SCU is not used, however since much code is shared between Cortex-A9 based OMAP4 (which uses SCU) and OMAP5, It does help to have inline functions returning error values when SCU is not present on the platform. arch/arm/mach-omap2/omap-smp.c which is common between OMAP4 and 5 handles the SCU usage only for OMAP4. This fixes the following build failure with OMAP5 only build: arch/arm/mach-omap2/built-in.o: In function `omap4_smp_init_cpus': arch/arm/mach-omap2/omap-smp.c:185: undefined reference to `scu_get_core_count' arch/arm/mach-omap2/built-in.o: In function `omap4_smp_prepare_cpus': arch/arm/mach-omap2/omap-smp.c:211: undefined reference to `scu_enable' Reported-by: Pekon Gupta <pekon@ti.com> Reported-by: Vincent Stehlé <v-stehle@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

CPU sleep and resume functions for Cortex-A9 based OMAP4 and Cortex-A15 based OMAP5 are different. Hence, even though we reuse most of the remaining file as part of OMAP4/5 consolidation, build OMAP4 specific sleep/resume operations only for OMAP4. SCU is not used OMAP5. This fixes the following build failure with OMAP5 only build: arch/arm/mach-omap2/built-in.o: In function `scu_gp_set': arch/arm/mach-omap2/sleep44xx.S:132: undefined reference to `scu_power_mode' arch/arm/mach-omap2/built-in.o: In function `scu_gp_clear': arch/arm/mach-omap2/sleep44xx.S:229: undefined reference to `scu_power_mode' Reported-by: Pekon Gupta <pekon@ti.com> Reported-by: Vincent Stehlé <v-stehle@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

of_property_read_string_index(...,&oh_name) in omap_dm_timer_init_one does not alter the value of 'oh_name' even if the relevant function fails and as 'oh_name' in stack may have a non-zero value, it would be misunderstood by timer code that DT has specified "ti,hwmod" property for timer. 'oh_name' in this scenario would be a junk value, this would result in module not being enabled by hwmod API's for timer, and in turn crash.

Power-up timing The DS2408 is sensitive to the power-on slew rate and can inadvertently power up with a test mode feature enabled. When this occurs, the P0 port does not respond to the Channel Access Write command. For most reliable operation, it is recommended to disable the test mode after every power-on reset using the Disable Test Mode sequence shown below. The 64-bit ROM code must be transmitted in the same bit sequence as with the Match ROM command, i.e., least significant bit first. This precaution is recommended in parasite power mode (VCC pin connected to GND) as well as with VCC power.

Some users have a large AoE target while others like to use many AoE targets at the same time. In the latter case, there is an opportunity to greatly improve aggregate throughput by allowing different threads to complete the I/O associated with each target.

Paul Clements authored
Currently, when a disconnect is requested by the user (via NBD_DISCONNECT ioctl) the return from NBD_DO_IT is undefined (it is usually one of several error codes). This means that nbd-client does not know if a manual disconnect was performed or whether a network error occurred. Because of this, nbd-client's persist mode (which tries to reconnect after error, but not after manual disconnect) does not always work correctly. This change fixes this by causing NBD_DO_IT to always return 0 if a user requests a disconnect. This means that nbd-client can correctly either persist the connection (if an error occurred) or disconnect (if the user requested it).

Change endpoint device name format to use a component tag value instead of device destination ID. RapidIO specification defines a component tag to be a unique identifier for devices in a network. RapidIO switches already use component tag as part of their device name and also use it for device identification when processing error management event notifications. Forming an endpoint's device name using its component tag instead of destination ID allows to keep sysfs device directories unchanged in case if a routing process dynamically changes endpoint's destination ID as a result of route optimization. This change should not affect any existing users because a valid device destination ID always should be obtained by reading "destid" attribute and not by parsing device name. This patch also removes switchid member from struct rio_switch because it simply duplicates the component tag and does not have other use than in device name generation.

This patch adds an option to build device driver for Tsi721 PCIe-to-SRIO bridge device as a kernel module. Currently this module cannot be unloaded because the existing RapidIO subsystem code does not support dynamic removal of local RapidIO controllers (TODO).

Update enumeration/discovery method registration mechanism to allow loading enumeration/discovery methods before all mports are registered. Existing statically linked RapidIO subsystem expects that all available RapidIO mport devices are initialized and registered before the enumeration/discovery method is registered. Switching to loadable mport device drivers creates situation when mport device driver can be loaded after enumeration/discovery method is attached (e.g., loadable mport driver in a system with statically linked RapidIO core and enumerator). This also will happen in a system with hot-pluggable RapidIO controllers. To remove the dependency on the initialization/registration order this patch introduces enumeration/discovery registration mechanism that supports arbitrary registration order of mports and enumerator/discovery methods. The following registration rules are implemented: - only one enumeration/discovery method can be registered for given mport ID (including RIO_MPORT_ANY); - when new enumeration/discovery methods tries to attach to the registered mport device, method with matching mport ID will replace a default method previously registered for given mport (if any); - enumeration/discovery method with target ID=RIO_MPORT_ANY will be attached only to mports that do not have another enumerator attached to them; - when new mport device is registered with RapidIO subsystem, registration routine searches for the enumeration/discovery method with the best matching mport ID; Signed-off-by: Alexandre Bounine <alexandre.bounine@idt.com> Cc: Matt Porter <mporter@kernel.crashing.org> Cc: Li Yang <leoli@freescale.com> Cc: Kumar Gala <galak@kernel.crashing.org> Cc: Andre van Herk <andre.van.herk@Prodrive.nl> Cc: Micha Nelissen <micha.nelissen@Prodrive.nl> Cc: Stef van Os <stef.van.os@Prodrive.nl> Cc: Jean Delvare <jdelvare@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Rework probe/remove routines to prevent rionet driver from monopolizing target RapidIO devices. Fix conflict with modular RapidIO switch drivers. Using one of RapidIO messaging channels rionet driver provides a service layer common to all endpoint devices in a system's RapidIO network. These devices may also require their own specific device driver which will be blocked from attaching to the target device by rionet (or block rionet if loaded earlier). To avoid conflict with device-specific drivers, the rionet driver is reworked to be registered as a subsystem interface on the RapidIO bus. The reworked rio_remove_dev() and rionet_exit() routines also include handling of individual rionet peer device removal which was not supported before.
