Analyze and fix the following issue in the Linux kernel code: MIPS: Kernel hangs occasionally during boot.
Problem Details: The Kernel hangs occasionally during boot after "Calibrating delay loop..". This is caused by the c0_compare_int_usable() routine in cevt-r4k.c returning false which causes the system to disable the timer and hang later. The false return happens because the routine is using a series of four calls to ir...

Analyze and fix the following issue in the Linux kernel code: Fix incorrect usage of NET_IP_ALIGN
Problem Details: The driver used NET_IP_ALIGN to remove some additional padding inside of the rx_fixup function. On many architectures NET_IP_ALIGN defaults to 2 which removed the correct amount of bytes. On MCORE2-machines commit ea812ca1b06113597adcd8e70c0f84a413d97544 introduces a change which sets NET_IP_ALIGN to ...

Analyze and fix the following issue in the Linux kernel code: drm/i915: Fix object refcount leak on mmappable size limit error path.
Problem Details: I've been seeing memory leaks on my system in the form of large (300-400MB) GEM objects created by now-dead processes laying around clogging up memory. I usually notice when it gets to about 1.2GB of them. Hopefully this clears up the issue, but I just found this bug by inspection. Signed-off-by: Er...

Problem Details: This patch adds a custom DSS reset function used on OMAPs from OMAP2 forward. The function doesn't actually do a reset, it only waits for the reset to complete. The reason for this is that on OMAP4 there is no possibility to do a SW reset, and on OMAP2/3 doing a SW reset for dss_core resets all the ot...
