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 469dded183 ("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 6eae1ace68 ("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.

file and memory sizes. The problem is that the section following the

switches to the data phdr before the start of the RODATA section.
