Arrange for a syntax check to always be done on the powerpc/mm/slb.c DBG() macro by defining it to pr_debug() for non-debug builds. Also, fix these related compile warnings: slb.c:273: warning: format '%04x' expects type 'unsigned int', but argument 2 has type 'long unsigned int slb.c:274: warning: format '%04x' expects type 'unsigned int', but argument 2 has type 'long unsigned int' Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

mpc52xx_uart_int and __uart_put_char both try to acquire the port->lock. Therefore the function sequence of: mpc52xx_uart_int--> ...-->flush_to_ldisc-->...-->__uart_put_char can potentially trigger a deadlock. To avoid this deadlock a fix similar to that found in the 8250.c serial driver is applied. The deadlock is avoided by releasing the lock before pushing a buffer and reacquiring it when completed.

Commit edd8ce67 (Use extended crashkernel command line on ppc64), changed the logic in reserve_crashkernel() which deals with the crashkernel= command line option. This introduced a bug in the case when there is no crashkernel= option, or it is incorrect. We would fall through and calculate the crash_size based on the existing values in crashk_res. If both start and end are 0, the default, we calculate the crash_size as 1 byte - which is wrong. Rework the logic so that we use crashk_res, regardless of whether it's set by the command line or via the device tree (see prom.c). Then check if we have an empty range (end == start), and if so make sure to set both end and start to zero (this is checked in machine_kexec_64.c). Then we calculate the crash_size once we know we have a non-zero range. Finally we always want to warn the user if they specify a base != 32MB, so remove the special case for that in the command line parsing case.

The current_thread_info() macro, used by preempt_count(), assumes the base address and size of the stack are THREAD_SIZE aligned. The emergency stack currently isn't either of these things, which could potentially cause problems anytime we're running on the emergency stack. That includes when we detect a bad kernel stack pointer, and also during early_setup_secondary().

There are userspace instrumentation tools that need to monitor spu context switches. This patch adds a new file called 'switch_log' to each spufs context directory that can be used to monitor the context switches. Context switch in/out and exit from spu_run are monitored after the file was first opened and can be read from it.

Board-specific defconfigs based on current mpc5200_defconfig, archival lite5200_defconfig, and [cm5200|motionpro|tqm5200]_defconfig from the linux-2.6-denx tree. Kernels build using these defconfigs were verified to boot with root filesystem mounted over NFS on Motion-PRO, TQM5200 and Lite5200B boards. CM5200 target was not tested due to hardware unavailability. Signed-off-by: Bartlomiej Sieka <tur@semihalf.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

The error handling for the mpc5200 fec interrupt is broken. The intended behaviour is like this: * If one of FEC_IEVENT_RFIFO_ERROR and FEC_IEVENT_XFIFO_ERROR happens, the datasheet says (MPC5200B User's Guide R1.2, p. 14-13): "When this occurs, software must ensure both the FIFO Controller and BestComm are soft-reset". * On any other error (non-TFINT) interrupt, just issue a debug message.

The original RapidIO driver suppose there is only one mpc85xx RIO controller in system. So, some data structures are defined as mpc85xx_rio global, such as 'regs_win', 'dbell_ring', 'msg_tx_ring'. Now, I changed them to mport's private members. And you can define multi RIO OF-nodes in dts file for multi RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in Freescale's silicon. And the mport operation function declaration should be changed to know which RapidIO controller is target.

The powerpc kernel maintains information about logical memory blocks in the lmb.memory structure, which is initialized and updated at boot time, but not when memory is added or removed while the kernel is running. This adds a hotplug memory notifier which updates lmb.memory when memory is added or removed. This information is useful for eHEA driver to find out the memory layout and holes. NOTE: No special locking is needed for lmb_add() and lmb_remove(). Calls to these are serialized by caller. (pSeries_reconfig_chain).

Hotplug memory remove notifier for 64-bit powerpc. This gets invoked by writing to /proc/ppc64/ofdt the string "remove_node " followed by the firmware device tree pathname of the node that needs to be removed. In response, this adjusts the sections and removes sysfs entries by calling __remove_pages(). Then it calls arch-specific code to get rid of the hardware MMU mappings for the section of memory.
