| * | [ARM] 3847/2: Convert LOMOMO to use struct device for GPIOsRichard Purdie2006-09-271-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert LOMOMO to use struct device * for GPIOs instead of struct locomo_dev. This enables access to the GPIOs from code which is not a locomo device itself (such as audio). Access for gpio 31 is removed for error handling (no such hardware exists).

However, no version of GCC supports conditionalizing asm statements. GCC 4.2 will correctly expand %? to the empty string in user asms. Earlier versions may reuse the condition from the previous instruction. In 'if (foo) asm ("bar%?");' this is somewhat likely to be right... but not reliable. So, the only safe thing to do is to remove the uses of %?. I believe the tlbflush.h occurances were supposed to be removed before, based on the comment about %? not working at the top of that file. Old versions of GCC could omit branches around user asms if the asm didn't mark the condition codes as clobbered. This problem hasn't been seen on any recent (3.x or 4.x) GCC, but it could theoretically happen. So, where %? was removed a cc clobber was added.

The original code evolved from rather bizarre support on Intel's "Lubbock" reference hardware, so that on more sensible hardware it doesn't work as well as it could/should. The change is just to teach the UDC driver how to use built-in PXA GPIO pins directly. This reduces the amount of board-specfic object code needed, and enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one. With VBUS sensing, the UDC is unclocked until a host is actually connected. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* | | [PATCH] Standardize pxx_page macrosDave McCracken2006-09-261-4/+4
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the changes necessary for shared page tables is to standardize the pxx_page macros. pte_page and pmd_page have always returned the struct page associated with their entry, while pte_page_kernel and pmd_page_kernel have returned the kernel virtual address. pud_page and pgd_page, on the other hand, return the kernel virtual address. Shared page tables needs pud_page and pgd_page to return the actual page structures. There are very few actual users of these functions, so it is simple to standardize their usage. Since this is basic cleanup, I am submitting these changes as a standalone patch. Per Hugh Dickins' comments about it, I am also changing the pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.
