Compare:

This says you are allocating enough space for foo. It can be reviewed
by looking at one line. If you change the type of foo it will still
work.
foo = kmalloc(sizeof(struct whatever), GFP_KERNEL);
There isn't enough information

Looks much better. Thanks! I am wondering whether we want to have this
marked for stable. The patch is quite non-intrusive and fires only when
we are really OOM. It is definitely better to try harder than go and

I think "installing a kernel with my changes for both drm and i915" takes more
time and effort to complete than "only updating DRM/i915 modules without
rebuilding the whole kernel". In some cases, that's beneficial.

Add hwcap2 attribute for x86.
Reserve 1st bit of HWCAP2 for exposing Xeon Phi ring 3 monitor/mwait.
With this userspace apps can detect Ring 3 MONITOR/MWAIT instructions.

many seq_file helpers exist for simplifying implementation of virtual files
especially, for /proc nodes. however, the helpers for iteration over
list_head are available but aren't adopted to implement /proc/vmallocinfo
currently.

ok,
These patches enable Intel Xeon Phi x200 feature to use MONITOR/MWAIT
instruction in ring 3 (userspace) Patches set MSR 0x140 for all logical CPUs.
Then expose it as CPU feature and introduces elf HWCAP capability for x86.

Add cpu feature for ring 3 monitor/mwait.

If processor is Intel Xeon Phi we enable user-level mwait feature.
Enabling this feature suppreses invalid-opcode error, when MONITOR/MWAIT
is called from ring 3.

Intel Xeon Phi x200 (codenamed Knights Landing) has MSR
MISC_THD_FEATURE_ENABLE 0x140.
Setting its 2nd bit make MONITOR and MWAIT instructions do not cause
invalid-opcode exception.
This commit adds this register prefixed by PHI and bit to msr-info.h
