mmc: at91/avr32/atmel-mci: fix DMA-channel leak on module unload 2013-05-08T03:33:14+00:00 Johan Hovold jhovold@gmail.com 2013-03-13T16:11:59+00:00 7ab9cbaa14125c8bf199b13c982a3606a1b5b01f commit 91cf54feecf815bec0b6a8d6d9dbd0e219f2f2cc upstream. Fix regression introduced by commit 796211b7953 ("mmc: atmel-mci: add pdc support and runtime capabilities detection") which removed the need for CONFIG_MMC_ATMELMCI_DMA but kept the Kconfig-entry as well as the compile guards around dma_release_channel() in remove(). Consequently, DMA is always enabled (if supported), but the DMA-channel is not released on module unload unless the DMA-config option is selected. Remove the no longer used CONFIG_MMC_ATMELMCI_DMA option completely.

arm: set the page table freeing ceiling to TASK_SIZE 2013-05-08T03:33:07+00:00 Catalin Marinas catalin.marinas@arm.com 2013-04-29T22:07:45+00:00 87855fa699dac0cdd02177905aa0fa1ef485ab07 commit 104ad3b32d7a71941c8ab2dee78eea38e8a23309 upstream. ARM processors with LPAE enabled use 3 levels of page tables, with an entry in the top level (pgd) covering 1GB of virtual space. Because of the branch relocation limitations on ARM, the loadable modules are mapped 16MB below PAGE_OFFSET, making the corresponding 1GB pgd shared between kernel modules and user space. If free_pgtables() is called with the default ceiling 0, free_pgd_range() (and subsequently called functions) also frees the page table shared between user space and kernel modules (which is normally handled by the ARM-specific pgd_free() function). This patch changes defines the ARM USER_PGTABLES_CEILING to TASK_SIZE when CONFIG_ARM_LPAE is enabled. Note that the pgd_free() function already checks the presence of the shared pmd page allocated by pgd_alloc() and frees it, though with ceiling 0 this wasn't necessary.
