The spinlock is only used in process context (register/unregister) since RCU is used for the nf_hook lists, switch to a mutex. Signed-off-by:

Use rcu_assign_pointer/rcu_dereference for ip_ct_attach pointer instead of self-made RCU and use rcu_read_lock to make sure the conntrack module doesn't disappear below us while calling it, since this function can be called from outside the netfilter hooks. Signed-off-by:

Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by:

Add the PS3 Virtual Frame Buffer Driver. As the actual graphics hardware cannot be accessed directly by Linux, ps3fb uses a virtual frame buffer in main memory. The actual screen image is copied to graphics memory by the GPU on every vertical blank, by making a hypervisor call. Signed-off-by:

Preallocate bootmem memory for the PS3 frame buffer device, which needs a large block of physically-contiguous memory. The size of this memory block is configurable: - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the default amount of memory (in MiB) allocated to the virtual frame buffer. - The early boot parameter `ps3fb=xxx' allows to override the default value. It will be rounded up to a multiple of 1 MiB, if needed.

fb_videomode_to_var(): reset the virtual screen parameters when converting from an fb_videomode to an fb_var_screeninfo. Without this the old virtual screen parameters are kept. Hence you cannot switch to a video mode with a lower resolution on frame buffer devices that don't support virtual screens and panning, as values are not supposed to be rounded down when they don't fit. I also reordered the assignments to match the order of the individual members. Signed-off-by:

Some of fb drivers uses atomic_t in bad manner, since there are still some race-prone gaps. Use mutexes to protect open/close code sections with ref_count testing and finally use simple uint. Signed-off-by:

The FB_S3TRIO driver: - has been marked as BROKEN for more than two years and - is still marked as BROKEN. Drivers that had been marked as BROKEN for such a long time seem to be unlikely to be revived in the forseeable future. But if anyone wants to ever revive this driver, the code is still present in the older kernel releases. Signed-off-by:
