Since the role_store() uses strncmp(), it's possible to refer
out-of-memory if the sysfs data size is smaller than strlen("host").
This patch fixes it by using sysfs_streq() instead of strncmp().

Livepatch uses ftrace for redirection to new patched functions. It means

Create a static key which allows to enable or disable TurboSched feature at
runtime.
This key is added in order to enable the TurboSched feature only when
required. This helps in optimizing the scheduler fast-path when the
TurboSched feature is disabled.
Also provide get/put methods to keep track
Provide an powerpc architecture specific implementation for defining the
turbo domain to make searching of the core to be bound within the NUMA.
The POWER9 systems have a pair of cores in the LLC domain. Hence to make
TurboSched more effective, increase the domain space for task packing
to search
The algorithm finds the first non idle core in the system and tries to
place a task in the idle CPU in the chosen core. To maintain
cache hotness, work of finding non idle core starts from the prev_cpu,
which also reduces task ping-pong behaviour inside of the core.
Define a new method to select_n
Small background tasks typically performs some housekeeping work and are
less important in the overall scheme of load balancing and scheduling.
So provide a way to mark the task which are small background noises with
the use of additional flag to the existing task attribute. Also provide an

Specify the method which returns cpumask within which to limit the

Use the get/put methods to add/remove the use of TurboSched support, such

Changes since v2 [3]:
- Qian Cai suggested that the extra boot option and page_ext ops is unnecessary
for a debugging option, unless somebody really complains about the overhead,
with numbers. So patch 2 is greatly simplified.
These are followups to [1] which made it to Linus meanwhile. Patch
As noted by Kirill, commit 7e2f2a0cd17c ("mm, page_owner: record page owner for
each subpage") has introduced an off-by-one error in __set_page_owner_handle()
when looking up page_ext for subpages. As a result, the head page page_owner
info is set twice, while for the last tail page, it's not set a
The commit 8974558f49a6 ("mm, page_owner, debug_pagealloc: save and dump
freeing stack trace") enhanced page_owner to also store freeing stack trace,
when debug_pagealloc is also enabled. KASAN would also like to do this [1] to
improve error reports to debug e.g. UAF issues. Kirill has suggested th
Commit 37389167a281 ("mm, page_owner: keep owner info when freeing the page")
has introduced a flag PAGE_EXT_OWNER_ACTIVE to indicate that page is tracked as
being allocated. Kirill suggested naming it PAGE_EXT_OWNER_ALLOCATED to make it
more clear, as "active is somewhat loaded term for a page".

Don't populate the array mapping on the stack but instead make it
static. Makes the object code smaller by 79 bytes.
