Some functions like kmalloc/kzalloc return NULL on failure. When NULL represents failure, !x is commonly used. This was done using Coccinelle: @@ expression *e; identifier l1; @@ e = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\)(...); ... - e == NULL + !e Signed-off-by:

Members of nbu2ss_udc structure can change device state, maintain completion state and control driver. Also provide access to read and write to register. Hence, exclusive access to nbu2ss_udc is required. The lock variable of type spinlock_t guarantees the exclusive access and protects it. In this patch, comment is added for spinlock_t definition, to fix the following checkpatch issue: CHECK: spinlock_t definition without comment Signed-off-by:

Unnecessary parentheses are removed as reported by checkpatch.pl to make coder nicer and to improve readability. Also coding style is improved as it's often nicer to read if &(foo[0]) is converted to foo like: memcpy(&(ap->bssid[0]), &(ap_info->bssid[0]), ETH_ALEN); memcpy(ap->bssid, ap_info->bssid, ETH_ALEN); Signed-off-by:

Lowmemory killer is sitting in the staging tree since 2008 without any serious interest for fixing issues brought up by the MM folks. The main objection is that the implementation is basically broken by design: - it hooks into slab shrinker API which is not suitable for this purpose. lowmem_count implementation just shows this nicely. There is no scaling based on the memory pressure and no feedback to the generic shrinker infrastructure. Moreover lowmem_scan is called way too often for the heavy work it performs. - it is not reclaim context aware - no NUMA and/or memcg awareness. As the code stands right now it just adds a maintenance overhead when core MM changes have to update lowmemorykiller.c as well. It also seems that the alternative LMK implementation will be solely in the userspace so this code has no perspective it seems. The staging tree is supposed to be for a code which needs to be put in shape before it can be merged which is not the case here obviously. Signed-off-by:

vc04_services has an ioctl interface to dump arbitrary memory to a custom debug log. This is typically only needed by diagnostic tools, and can potentially be a security issue if the devtmpfs node doesn't have adequate permissions set. Since the ability to dump memory still has debugging value, create a new build configuration and disable the feature by default. Signed-off-by:

This patch adds compatibility wrappers for the ioctls exposed by vchiq/vc04_services. The compat ioctls are completely implemented on top of the native ioctls. No existing lines are modified. While the ideal approach would be to cleanup the existing code, this path is simplier and easier to review. While it does have a small runtime performance penality vs seperating the existing code into wrapper+worker functions, the penality is small since only the metadata is copied back onto the 32 bit user mode stack. The on top of approach is the approach used by several existing performance critical subsystems of Linux such as the DRM 3D graphics subsystem. Testing: 1. A 32 bit chroot was created on a RPI 3 and vchiq_test was built for armhf. The usual tests were run such as vchiq_test -f 10 and vchiq_test -p. 2. This patch was copied onto the shipping version of the Linux kernel used for the RPI and that kernel was built for arm64. That kernel was used to boot Raspbian. Many of the builtin features are now functional such as the "hello_pi" examples, and minecraft_pi. Signed-off-by:

The camera driver passes messages back and forth between the firmware with requests and replies. One of the fields of the message header called context is a pointer so the size changes between 32 bit and 64 bit. The context field is used to pair reply messages from the firmware with request messages from the kernel. The simple solution would be to use the padding field for the upper 32 bits of pointers, but this would rely on the firmware always copying the pad field. So instead handles are generated that are 32 bit numbers and a mapping stored in a btree as implemented by the btree library in the kernel lib directory. The mapping pairs the handle with the pointer to the actual data. The btree library was chosen since it's very easy to use and red black trees would be overkill. The camera driver also now forces in the btree library if the camera is included in the build. The btree library is a hidden configuration option. Signed-off-by:

The camera driver passes messages back and forth between the firmware with requests and replies. One of the fields of the message header called control_service is a pointer so the size changes between 32 bit and 64 bit. Luckly, the field is not interperated by the driver, so it can be changed to a u32 which has a fixed size. Signed-off-by:

The camera code has an explicit cache flush operation which is not portable. Now that vc04_services is using portable DMA APIs that already do the cache flushing, explicit flushes should no longer be needed. The one call to __cpuc_flush_dcache_area has been removed. Testing: The offical V2 camera for the RPI was tested on a RPI 3 running in 32 bit mode(armhf). The cheese application and ffmpeg was used to view and stream video from the camera. Nothing new seems to be broken without the cache flushing. Signed-off-by:
