* [ARM] fix section-based ioremapRussell King2009-01-25
| | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | spin_lock functions take a pointer to the lock, not the lock itself. This error was noticed by compiling ebsa110_defconfig for linux-rt where the locking functions obviously are more picky about their arguments.

* [ARM] clkdev: fix clock matchingRussell King2009-01-24
| | | | | | | | | | | | | | | | | 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.

* ARM: OMAP: Fix ASoC by enabling writes to XCCR and RCCR McBSP registers, v3Tony Lindgren2009-01-15
| | | | | | | | | | | | | | | | | | | | | | | | | 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'.

| * powerpc/83xx: Make serial ports work on MPC8315E-RDB w/ FSL U-BootsAnton Vorontsov2009-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FSL U-Boots use /soc8315@e0000000 node to search and fixup serial nodes' clock-frequency properties. Though in upstream kernels we use new naming convention -- for IMMR address space dts files specify /immr@e0000000 nodes. This makes FSL U-Boots fail to fixup the clock frequencies, and that leads to serial ports misbehaviour. We can workaround the issue by filling the clock frequency values manually. p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for ethernet nodes, so users should either change the .dts file locally or set MAC address via `ifconfig hw ether' command.

| * powerpc/powermac: Fix occasional SMP boot failureBenjamin Herrenschmidt2009-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PowerMac kernel occasionally fails to bring up the secondary CPUs on SMP, the trigger factor seem to be fairly random and related to location of code and data. This appears to be due to the initial loading of the TOC value by the secondary processor which now happens before we clear HID4:RM_CI (Real Mode Cache Invalidate). This bit should really be cleared before we do any load or store other than fetching code. This fix works based on the assumption that all SMP 64-bit PowerMacs use variants of the 970, which fortunately is true, by explicitely clearing that bit, adding an slbia for good measure as RM_CI mode is known to create bogus ERAT entries. I also removed some spurrious debug output that was left enabled by mistake while at it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hvc_console is setting low_latency unconditionally, but some clients are interrupt driven and will call hvc_poll from irq context. This will cause tty_flip_buffer_push to be called from irq context, and it very clearly states it must not be called from IRQ when low_latency is specified.

To indicate that a memory range is prefetchable, mark it in the dts file with 42000000 instead of 02000000. A powepc pci_controller is allowed three memory ranges, any of which may be prefetchable. However, the PCI-PCI bridge configuration space only has one field for "non-prefetchable memory behind bridge", which has a 32 bit address, and one field for "prefetchable memory behind bridge", which may have a 64 bit address. These are PCI bus addresses, not CPU physical addresses. So really you're only allowed one memory range of each type. And if you want the range at a PCI address above 32 bits you must make it prefetchable. Signed-off-by: Trent Piepho <tpiepho@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
