The current implementation of dmi_name_in_vendors() is an invitation to lazy coding and false positives [1]. Searching for a string in 8 know what you're looking for, so you should know where to look. strstr isn't fast, especially when it fails, so we should avoid calling it when it just can't succeed. Looking at the current users of the function, it seems clear to me that they are looking for a system or board vendor name, so let's limit dmi_name_in_vendors to these two DMI fields. This much better matches the function name, BTW. [1] We currently have code looking for short names in DMI data, such as "IBM", "ASUS" or "Acer". I let you guess what will happen the day other vendors ship products named, for example, "SCHREIBMEISTER", "PEGASUS" or "Acerola".

Commit c9f01245 ("oom: remove oom_disable_count") has removed the oom_disable_count counter which has been used for early break out from oom_badness so we could never select a task with oom_score_adj set to OOM_SCORE_ADJ_MIN (oom disabled). Now that the counter is gone we are always going through heuristics calculation and we always return a non zero positive value. This means that we can end up killing a task with OOM disabled because it is indistinguishable from regular tasks with 1% resp. CAP_SYS_ADMIN tasks with 3% usage of memory or tasks with oom_score_adj set but OOM enabled. Let's break out early if the task should have OOM disabled.

The driver for the DigsyMTC display configuration EEPROMs device got added by commit 469dded1 ("misc/eeprom: add eeprom access driver for digsy_mtc board"). Its Kconfig symbol depends on PPC_MPC5200_GPIO. But at the time that driver got added PPC_MPC5200_GPIO was already renamed to GPIO_MPC5200, by commit 6eae1ace ("gpio: Move mpc5200 gpio driver to drivers/gpio"). So make this driver depend on GPIO_MPC5200. And since GPIO_MPC5200 itself implies that GPIOLIB is set, that dependency can be dropped.

'readelf -n' on the s390 vmlinux file generates lots of warnings about corrupt notes. The reason is that the 'NOTE' program header has incorrect file and memory sizes.

Do * it explicitely to guard against PREEMPT_RT kernel. Just that this has never been tested on a RT kernel which would have granted that nonsense with a might_sleep() warning because dev->vblank_time_lock is converted to a "sleeping" spinlock on RT.
