* gpio: <linux/gpio.h> and "no GPIO support here" stubsDavid Brownell2008-03-04
| | | | | | | | | | | | | | | | | | Add a <linux/gpio.h> defining fail/warn stubs for GPIO calls on platforms that don't support the GPIO programming interface. That includes the arch-specific implementation glue otherwise. This facilitates a new model for GPIO usage: drivers that can use GPIOs if they're available, but don't require them. One example of such a driver is NAND driver for various FreeScale chips. On platforms update with GPIO support, they can be used instead of a worst-case delay to verify that the BUSY signal is off. (Also includes a couple minor unrelated doc updates.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the use cases for the supported cpuid list is to create a "greatest common denominator" of cpu capabilities in a server farm. As such, it is useful to be able to get the list without creating a virtual machine first. Since the code does not depend on the vm in any way, all that is needed is to move it to the device ioctl handler. The capability identifier is also changed so that binaries made against -rc1 will fail gracefully. Signed-off-by: Avi Kivity <avi@qumranet.com>

The commit adjusts bio according to memory alignment (queue_dma_alignment). However, memory alignment is NOT padding alignment. This adjustment also breaks SG_IO friends and bsg.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eric Sandeen tracked an XFS on ARM corruption bug down to a function under fs/xfs/ involving some get_unaligned() calls on u64 pointers. As it turns out, calling ARM's get_unaligned() on a u64 pointer pointing to the following byte sequence: 80 81 82 83 84 85 86 87 would return ffffffff83828180 (LE mode.) This turns out to be because of implicit u8 -> int promotion in ARM's implementation of various helpers for get_unaligned(), causing them to accidentally return signed instead of unsigned values, which in turn caused the subsequent casts to unsigned long long in __get_unaligned_8_[bl]e() to sign-extend the lower words. Fix by casting the return values of __get_unaligned_[24]_[bl]e() to unsigned int.

If a program using huge pages does not explicitly unmap them, they remain mapped (and therefore, are lost) after the program exits. I observed that the free huge page count in /proc/meminfo decreased when running my program, and it did not increase after the program exited. After running the program a few times, no more huge pages could be allocated. The reason for this seems to be that the x86 pmd_bad and pud_bad consider pmd/pud entries having the PSE bit set invalid. I think there is nothing wrong with this bit being set, it just indicates that the lowest level of translation has been reached. This bit has to be (and is) checked after the basic validity of the entry has been checked, like in this fragment from follow_page() in mm/memory.c: if (pmd_none(*pmd) || unlikely(pmd_bad(*pmd))) goto no_page_table; if (pmd_huge(*pmd)) { BUG_ON(flags & FOLL_GET); page = follow_huge_pmd(mm, address, pmd, flags & FOLL_WRITE); goto out; } Note that this code currently doesn't work as intended if the pmd refers to a huge page, the pmd_huge() check can not be reached if the page is huge. Extending pmd_bad() (and, for future 1GB page support, pud_bad()) to allow for the PSE bit being set fixes this. For similar reasons, allowing the NX bit being set is necessary, too. I have seen huge pages having the NX bit set in their pmd entry, which would cause the same problem. Signed-Off-By: Hans Rosenfeld <hans.rosenfeld@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
