2010-02-23omap: sdma: Limit the secure reserve channel fix for omap3Santosh Shilimkar
The commit 'ba50ea7e' reserves DMA channels 0 and 1 on high security devices, in order to avoid collision between kernel dma transfers and ROM code dma transfers. This fix is applicable only for OMAP3 so add an appropriate check.

2010-02-23omap3/4: uart: fix full-fifo write abortSantosh Shilimkar
This patch is addition to the already merged commit on non-empty uart fifo read abort. "ce13d4716a276f4331d78ba28a5093a63822ab95" OMAP3630 and OMAP4430 UART IP blocks have a restriction on TX FIFO too. If you try to write to the tx fifo when it is full, the system aborts. More details on this thread are here: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg19447.html This can be easily reproducible by not suppressing interconnect errors or long duration testing where continuous prints over console from multiple threads. This patch is addressing the issue by ensuring that write is not issued while fifo is full. A timeout is added to avoid any hang on fifo-full for 10 mS which is unlikely case. Patch is validated on OMAP3630 and OMAP4 SDP. V2 version removed the additional 1 uS on every TX as per Tony's suggestion Signed-off-by: Woodruff Richard <r-woodruff2@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> CC: Ghorai Sukumar <s-ghorai@ti.com> Reviewed-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-02-23omap4: multi-omap: Allow build to workSantosh Shilimkar
The musb support is enabled in omap3 platforms. For omap4 only board support is available and the driver still isn't supported. Because of this build with omap3_defconfig used for multi-omap doesn't work on omap4430 sdp. This patch avoids usb_musb_init() by adding a cpu check in the board file.

2010-02-20ARM: make_coherent(): fix problems with highpte, part 2Russell King
update_mmu_cache() is called with the page table for the faulted-in page still mapped. We need to modify the PTE for this page to ensure coherency with other shared mappings when multiple shared mappings exist within a MM. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-02-20MM: Pass a PTE pointer to update_mmu_cache() rather than the PTE itselfRussell King
On VIVT ARM, when we have multiple shared mappings of the same file in the same MM, we need to ensure that we have coherency across all copies. We do this via make_coherent() by making the pages uncacheable. This used to work fine, until we allowed highmem with highpte - we now have a page table which is mapped as required, and is not available for modification via update_mmu_cache(). Ralf Beache suggested getting rid of the PTE value passed to update_mmu_cache(): On MIPS update_mmu_cache() calls __update_tlb() which walks pagetables to construct a pointer to the pte again. Passing a pte_t * is much more elegant. Maybe we might even replace the pte argument with the pte_t? Ben Herrenschmidt would also like the pte pointer for PowerPC: Passing the ptep in there is exactly what I want. I want that -instead- of the PTE value, because I have issue on some ppc cases, for I$/D$ coherency, where set_pte_at() may decide to mask out the _PAGE_EXEC. So, pass in the mapped page table pointer into update_mmu_cache(), and remove the PTE value, updating all implementations and call sites to suit.

2010-02-20ARM: allow alignment fault mode to be configured at kernel bootRussell King
Some glibc versions intentionally create lots of alignment faults in their gconv code, which if not fixed up, results in segfaults during boot. This can prevent systems booting properly. There is no clear hard-configurable default for this; the desired default depends on the nature of the userspace which is going to be booted. So, provide a way for the alignment fault handler to be configured via the kernel command line. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
