| | * drm: Copy back ioctl data to userspace regardless of return code.Michel Dänzer2009-05-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a regression from commit 9d5b3ffc42f7820e8ee07705496955e4c2c38dd9 ('drm: fixup some of the ioctl function exit paths'): The vblank ioctl needs to update the userspace parameters when interrupted by a signal, which was prevented by the return code check. This could cause the X server to hang in drmWaitVBlank(). Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
| | * drm: Round size of SHM maps to PAGE_SIZEBenjamin Herrenschmidt2009-05-191-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, userspace can fail to obtain the SAREA mapping (among other reasons) if it passes SAREA_MAX to drmAddMap without aligning it to the page size. This breaks for example on PowerPC with 64K pages and radeon despite the kernel radeon actually doing the right rouding in the first place. The way SAREA_MAX is defined with a bunch of ifdef's and duplicated between libdrm and the X server is gross, ultimately it should be retrieved by userspace from the kernel, but in the meantime, we have plenty of existing userspace built with bad values that need to work. This patch works around broken userspace by rounding the requested size in drm_addmap_core() of any SHM map to the page size. Since the backing memory for SHM maps is also allocated within addmap_core, there is no danger of adjacent memory being exposed due to the increased map size. The only side effect is that drivers that previously tried to create or access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL), will now succeed at the cost of a little bit more memory used if that happens to be when the map is created.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The address range size calculation inside local_flush_tlb_kernel_range() is being truncated by a too small size variable holder on 64-bit systems. The truncated size can result in an erroneous tlbsize check that means we sit spinning inside a loop trying to flush a hige number of TLB entries. This is for all intents and purposes a system hang. Fix by using an appropriately sized valiable to hold the size. [Ralf: Greg's original patch submission identified the issue and fixed one instance in tlb-r4k.c but there there were several more.

| | * | [ARM] Double check memmap is actually valid with a memmap has unexpected ↵Mel Gorman2009-05-184-18/+48

In FLATMEM, it is expected that holes always have valid memmap as long as there is valid PFNs either side of the hole. In SPARSEMEM, it is assumed that a valid section has a memmap for the entire section. However, ARM and maybe other embedded architectures in the future free memmap backing holes to save memory on the assumption the memmap is never used. The page_zone linkages are then broken even though pfn_valid() returns true. A walker of the full memmap must then do this additional check to ensure the memmap they are looking at is sane by making sure the zone and PFN linkages are still valid. This is expensive, but walkers of the full memmap are extremely rare. This was caught before for FLATMEM and hacked around but it hits again for SPARSEMEM because the page_zone linkages can look ok where the PFN linkages are totally screwed. This looks like a hatchet job but the reality is that any clean solution would end up consumning all the memory saved by punching these unexpected holes in the memmap. For example, we tried marking the memmap within the section invalid but the section size exceeds the size of the hole in most cases so pfn_valid() starts returning false where valid memmap exists. Shrinking the size of the section would increase memory consumption offsetting the gains. This patch identifies when an architecture is punching unexpected holes in the memmap that the memory model cannot automatically detect and sets ARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx which is the model sub-architecture this has been reported on but may expand later. When set, walkers of the full memmap must call memmap_valid_within() for each PFN and passing in what it expects the page and zone to be for that PFN. If it finds the linkages to be broken, it assumes the memmap is invalid for that PFN. Signed-off-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

It also allows the uart clocks to be stopped when there are no users.

So the definition needs to be 4. This fixes also a cold reset HW bug in OMAP3430 ES3.x where some of the efuse bits are not isolated during wake-up from off mode. This can cause randomish cold resets with off mode. Enabling the USBTLL hardware SAVEANDRESTORE causes the core power up assert to be delayed in a way that we will not get faulty values when boot ROM is reading the unisolated registers.

It also includes a fix for a bogus NULL pointer check in CIFSSMBQueryUnixSymLink that Jeff Moyer spotted. It's possible for CIFSSMBQueryUnixSymLink to return without setting target_path to a valid pointer. If that happens then the current value to which we're initializing this pointer could cause an oops when it's kfree'd. This patch is a little more comprehensive than the last patches. It reorganizes cifs_follow_link a bit for (hopefully) better readability. It should also eliminate the uneeded allocation of full_path on servers without unix extensions (assuming they can get to this point anyway, of which I'm not convinced). On a side note, I'm not sure I agree with the logic of enabling this query even when unix extensions are disabled on the client. It seems like that should disable this as well. But, changing that is outside the scope of this fix, so I've left it alone for now.

Allow the audio driver to see a cache of these values for inspection during interrupt context. To do this we need to stop satisfying any bits from volatile registers from cache - there's no real benefit from doing so anyway, we did the read already.
