| * [ARM] fix section-based ioremapRussell King2009-01-251-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tomi Valkeinen reports: Running with latest linux-omap kernel on OMAP3 SDP board, I have problem with iounmap(). It looks like iounmap() does not properly free large areas. Below is a test which fails for me in 6-7 loops. for (i = 0; i < 200; ++i) { vaddr = ioremap(paddr, size); if (!vaddr) { printk("couldn't ioremap\n"); break; } iounmap(vaddr); } The changes to vmalloc.c weren't reflected in the ARM ioremap implementation. Turns out the fix is rather simple. Tested-by: Tomi Valkeinen <tomi.valkeinen@nokia.com> Tested-by: Matt Gerassimoff <mgeras@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * [ARM] clkdev: fix clock matchingRussell King2009-01-241-6/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old matching algorithm was too fuzzy, causing false positives. For example, when asked for device D connection C1 and we only find device D connection C2, we return that as a valid match despite the connection names being different. Change the algorithm such that: An entry with a NULL ID is assumed to be a wildcard. If an entry has a device ID, it must match If an entry has a connection ID, it must match However, we maintain the order of precidence while still only doing a single pass over all entries: dev+con > dev only > con only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes old platform devices. Alsa should now be using the ASoC driver. For boards not yet using ASoC, please see sound/soc/omap/osk5912.c. Add dummy aic23_power_up and aic23_power_down functions for 770 to keep things compiling. Remove references to omap_gpio_switch, and unused h2_nand_dev_ready function. This patch is based on an earlier patch by Arun KS.

| * ARM: OMAP: Fix ASoC by enabling writes to XCCR and RCCR McBSP registers, v3Tony Lindgren2009-01-152-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables writing to McBSP Transmit Configuration Control Register (XCCR) and Receive Configuration Control Register (RCCR) for 2430/34xx platforms. It also adds XCCR, RCCR entries in McBSP register configuration structure and bit definitions for both registers. If we enable the writing to CCR registers for 2430/34xx and don't set the default values (setting 0 as a consequence) in ASoC driver, the Transmit/Receive DMA mode gets disabled and the the transmission/reception doesn't happen, ending with a "write error: Input/Output error" when playing with 'aplay'. Also define dummy CCR registers for omap1. Cc: Jarkko Nikula <jarkko.nikula@nokia.com> Signed-off-by: Misael Lopez Cruz <x0052729@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

But this resulted in modpost failures if there where no in-kernel users because then insw & friends were not linked in. Fix this by including PeeCeeI.o in the kernel unconditionally. The only drawback for this solution is that a nonmodular kernel will always include insw & friends no matter if they are in use or not.

The script was originally written by Arnd Bergman and exten by me to cover a few more files. When the header files differed the script uses the following: The original m68k file is named <file>_mm.h [mm for memory manager] The m68knommu file is named <file>_no.h [no for no memory manager] The files uses the following include guard: This include gaurd works as the m68knommu toolchain set the __uClinux__ symbol - so this should work in userspace too. Merging the header files for m68k and m68knommu exposes the (unexpected?) ABI differences thus it is easier to actually identify these and thus to fix them. The commit has been build tested with both a m68k and a m68knommu toolchain - with success. The commit has also been tested with "make headers_check" and this patch fixes make headers_check for m68knommu.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Precreate stop_machine threads in case the machine supports ETR/STP. Otherwise we might deadlock if a time sync operation gets scheduled and the creation of stop_machine threads would cause disk I/O. This is just the minimal fix. The real fix would be to only precreate stop_machine threads if ETR/STP is actually used. But that would be a rather large and complicated patch.

| * | | | | [S390] cputime: fix lowcore initialization on cpu hotplugHeiko Carstens2009-01-231-0/+4

On initial start of secondary cpus this leads to the situation where per thread user/system_timer values are larger than the corresponding contents of the lowcore. When later calculating time spent in user/system context the result can be negative. So for cpu hotplug we should manually initialize lowcore values.

The 31 bit pointer passed to the system call is extended to 64 bit, but the high order bits are not set to zero. The kernel detects the invalid user space pointer and returns -EFAULT. To solve the problem, sys32_sigaltstack_wrapper() instead of sys32_sigaltstack() has to be called. The wrapper function sets the high order bits to zero.

CM contains, among other blocks, an Interrupt Generator (IG) and a Clock and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are supported over dmaengine and irq-chip APIs respectively. IDMAC is a specialised DMA controller, its DMA channels cannot be used for general-purpose operations, even though it might be possible to configure a memory-to-memory channel for memcpy operation. This driver will not work with generic dmaengine clients, clients, wishing to use it must use respective wrapper structures, they also must specify which channels they require, as channels are hard-wired to specific IPU functions.
