As reported by checkpatch.pl strict_strtoul should be replaced. It was replaced with kstrtouint since async->max_bufsize is an unsigned int anyway. Signed-off-by:

The "proper" way to do this is to work with the existing in-kernel tracing subsystem and work to get the missing features that are in lttng into those subsystems.

TILER/DMM provides two features for omapdrm GEM objects: 1) providing a physically contiguous view to discontiguous memory for hw initiators that cannot otherwise support discontiguous buffers (DSS scanout, IVAHD video decode/encode, etc) 2) providing untiling for 2d tiled buffers, which are used in some cases to provide rotation and reduce memory bandwidth for hw initiators that tend to access data in 2d block patterns. For 2d tiled buffers, there are some additional complications when it comes to userspace mmap'ings. For non-tiled buffers, the original (potentially physically discontiguous) pages are used to back the mmap. For tiled buffers, we need to mmap via the tiler/dmm region to provide an unswizzled view of the buffer. But (a) the buffer is not necessarily pinned in TILER all the time (it can be unmapped when there is no DMA access to the buffer), and (b) when they are they are pinned, they not necessarily page aligned from the perspective of the CPU. And non-page aligned userspace buffer mapping is evil. To solve this, we reserve one or more small regions in each of the 2d containers when the driver is loaded to use as a "user-GART" where we can create a second page-aligned mapping of parts of the buffer being accessed from userspace. Page faulting is used to evict and remap different regions of whichever buffers are being accessed from user- space. Signed-off-by:

Dynamic Memory Manager (DMM) is a hardware block in the OMAP4+ processor that contains at least one TILER instance. TILER, or Tiling and Isometric Lightweight Engine for Rotation, provides IOMMU capabilities through the use of a physical address translation table. The TILER also provides zero cost rotation and mirroring. The TILER provides both 1D and 2D access by providing different views or address ranges that can be used to access the physical memory that has been mapped in through the PAT. Access to the 1D view results in linear access to the underlying memory. Access to the 2D views result in tiled access to the underlying memory resulted in increased efficiency. The TILER address space is managed by a tiler container manager (TCM) and allocates the address space through the use of the Simple Tiler Allocation algorithm (SiTA). The purpose of the algorithm is to keep fragmentation of the address space as low as possible. Signed-off-by:

In commit 834d0ee3 (uintxy_t removal) not all changes were trival text replacements, some converted u64 -> dma_addr_t. In some configurations dma_addr_t is a u32, meaning that some bit operations cause build warnings. From Randy Dunlap: ---------------- on i386 (X86_32) builds: drivers/staging/et131x/et131x.c:2483:8: warning: right shift count >= width of type drivers/staging/et131x/et131x.c:2531:8: warning: right shift count >= width of type ---------------- Removed these by reverting dma_addr_t back to u64 types, as well as reverting some other non-trivial changes from the aforementioned commit.

The irq handler processes queued mei clients connect requests, which were not transferred to the device in ioctl context due to unavailability of the write buffer. The handler may transfer the connection request only if there is no other ongoing requests for the same mei id. This condition was implemented inversely which depending on the write buffer availability lead to seemingly random failures during connection attempts.

The allocation of zram->compress_buffer is misssing a GFP_* specifier. This is equivalent to GFP_NOWAIT but it is more likely a omission. Since the allocation just above it uses GFP_KERNEL, there is no reason to use GFP_NOWAIT here. Therefore, add GFP_KERNEL. Signed-off-by:

Set the length field of the scatter gather elements correctly when we create the bounce buffer. When we use the bounce buffer for a "write" operation, the act of copying to the bounce buffer, correctly deals with this issue. However, on the "read" side, the current code was not correctly setting the buffer length. Fix this bug. Note that when we copy from the bounce buffer (for the read case), the amount we copy is controlled by the original scatter gather list given to the driver. Signed-off-by:
