* [PATCH] ARM: Ensure DMA-bounced buffers are properly written to RAMRussell King2005-06-20
| | | | | | | | | | When DMA bounce buffers were unmapped and the data was memcpy'd to the original buffer, we were not ensuring that the data was written to RAM. This means that there was the potential for page cache pages to have different cache states depending whether they've been bounced or not. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | flush_dcache_page() did nothing for these caches, but since they suffer from I/D cache coherency issues, we need to ensure that data is written back to RAM. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | Create a temporary page table to startup secondary processors.

| * [PATCH] ARM SMP: Fix vector entryRussell King2005-05-31
| | | | | | | | | | | | | | | | | | | | The current vector entry system does not allow for SMP. In order to work around this, we need to eliminate our reliance on the fixed save areas, which breaks the way we enable alignment traps. This patch changes the way we handle the save areas such that we can have one per CPU. Signed-off-by: Russell King <rmk@arm.linux.org.uk>

In order to work around this, we need to eliminate our reliance on the fixed save areas, which breaks the way we enable alignment traps.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CompactFlash memories) Patch from David Brownell The ARM generic Kconfig filters out IDE options ... except for an error prone ARMload of special cases. This adds one general case to the systems that will offer IDE options: kernels with PCMCIA support, which probably want to use IDE to access CompactFlash cards. This might allow many (most?) of the other cases to disappear, for systems that only see IDE hardware through CF cards. Right now this one patch is used to gate access to CF cards, including MicroDrives, for both omap_cf and at91_cf drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Deepak Saxena The IXDP2800 bootloader does not disable IRQs before jumping into the kernel and this is causing the Grand Unified KGDB to crash the system when we do an early call to trap_init() and irq handlers have not yet been registered.

* | [PATCH] ARM: 2694/1: [s3c2410/dma] release irq properly to fix kernel oopsAlbrecht Dreß2005-06-03
|/ | | | | | | | | | | | | | Patch from Albrecht Dreß Problem: When a module requests a DMA channel via the function s3c2410_dma_request(), this function requests the appropriate irq under the name of the client module. When the client module is unloaded, it calls s3c2410_dma_free() which does not free the irq. Consequently, when e.g. running "cat /proc/interrupts", the irq owner points to freed memory, leading to a kernel oops.
