Reset methods don't have access to phys link status for slave links and may incorrectly indicate device presence causing unnecessary probe failures for unoccupied links. This patch clears device class to NONE during post-reset processing if phys link is offline. As on/offlineness semantics is strictly defined and used in multiple places by the core layer, this won't change behavior for drivers which don't use slave links.

Slave link action mask is transferred to master link and all the EH actions are taken by the master link. ata_eh_about_to_do() and ata_eh_done() are called with ATA_EH_ALL_ACTIONS to clear the slave link actions during transfer. This always sets ATA_PFLAG_RECOVERED flag causing spurious "EH complete" messages. Don't set ATA_PFLAG_RECOVERED for slave link actions.

ATA_EHI_NO_AUTOPSY and ATA_EHI_QUIET are used to control the behavior of EH. As only the master link is visible outside EH, these flags are set only for the master link although they should also apply to the slave link, which causes spurious EH messages during probe and suspend/resume. This patch transfers those two flags to slave ehc.i before performing slave autopsy and reporting. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Since the ehca device driver does not support dynamic memory add and remove operations, the driver must explicitly reject such requests in order to prevent unpredictable behaviors related to existing memory regions that cover all of memory being used by InfiniBand protocols in the kernel. The solution (for now at least) is to add a memory notifier to the ehca device driver and if a request for dynamic memory add or remove comes in, ehca will always reject it. The user can add or remove memory by hot-removing the ehca adapter, performing the memory operation, and then hot-adding the ehca adapter back.

Because ehca adapters can differ in the maximum number of QPs and CQs we have to save the maximum number of these ressources per adapter and not globally per ehca driver. This fix introduces 2 new members to the shca structure to store the maximum value for QPs and CQs per adapter. The module parameters are now used as initial values for those variables. If a user selects an invalid number of CQs or QPs we don't print an error any longer, instead we will inform the user with a warning and set the values to the respective maximum supported by the HW.

The Mellanox ConnectX can operate as an InfiniBand adapter, as an Ethernet NIC, or as a Fibre Channel (FC) HBA. The kernel has a low-level driver, mlx4_core, which handles multiplexing access to the device, and there is also already an InfiniBad driver, mlx4_ib. This patch adds a new driver, mlx4_en, which implements a standard Ethernet NIC driver.

Multi-protocol adapters support different port types. Each consumer of mlx4_core queries for supported port types; in particular mlx4_ib can no longer assume that all physical ports belong to it. Port type is configured through a sysfs interface. When the type of a port is changed, all mlx4 interfaces are unregistered, and then registered again with the new port types.

For ethernet support, we need to reserve QPs for the ethernet and fibre channel driver. The QPs are reserved at the end of the QP table. (This way we assure that they are aligned to their size) We need to consider these reserved ranges in bitmap creation, so we extend the mlx4 bitmap utility functions to allow reserved ranges at both the bottom and the top of the range.

This adds relocatable kernel support for kdump. With this one can use the same regular kernel to capture the kdump. A signature (0xfeed1234) is passed in r6 from panic code to the next kernel through kexec_sequence and purgatory code. The signature is used to differentiate between kdump kernel and non-kdump kernels. The purgatory code compares the signature and sets the __kdump_flag in head_64.S. During the boot up, kernel code checks __kdump_flag and if it is set, the kernel will behave as relocatable kdump kernel. This kernel will boot at the address where it was loaded by kexec-tools ie. at the address reserved through crashkernel boot parameter. CONFIG_CRASH_DUMP depends on CONFIG_RELOCATABLE option to build kdump kernel as relocatable. So the same kernel can be used as production and kdump kernel. This patch incorporates the changes suggested by Paul Mackerras to avoid GOT use and to avoid two copies of the code.

The patch provides the hvc_resize() function to update the terminal window dimensions (struct winsize) for a specified hvc console. The function stores the new window size and schedules a function that finally updates the tty winsize and signals the change to user space (SIGWINCH). Because the winsize update must acquire a mutex and might sleep, the function is scheduled instead of being called from hvc_poll() or khvcd. This patch uses the tty_do_resize() routine from the tty layer. A pending resize work is canceled in hvc_close() and hvc_hangup().

If put_char() routine of a hvc console backend returns 0, then the hvc console starts looping in the following scenarios: 1. hvc_console_print() If put_char() returns 0 then the while loop may loop forever. I have added the missing check for 0 to throw away console messages. 2. khvcd may loop: The thread calls hvc_poll() --> hvc_push()... if there are still buffered data then the HVC_POLL_WRITE bit is set and causes the khvcd thread to loop (if yield() returns immediately). However, instead of looping, the khvcd thread could sleep for MIN_TIMEOUT (doing the same as for get_chars()). The MIN_TIMEOUT is set if hvc_push() was not able to write data to the backend. If data has been written, the timeout is set to 0 to immediately re-schedule hvc_poll().

This adds basic support for the GPIOs in the twl4030 power management chip. That includes two open drain LED drivers, and the use of GPIO-0 (and GPIO-1) as MMC/SD card detect switches which can control whether the VMMC1 (and VMMC2) regulators are active. This version of the code has a debounce call that will probably be replaced before long, when a more generic interface exists.
