So,
This is a proposition to handle the cputime accounting without the
tick to prepare for stopping the tick further idle.
I have managed to reuse and generalize the kernel/user boundary
hooks used by RCU. This way we can minimize the changes in archs
that don't support virtual cputime and we
Create a new subsystem that handles the hooks on kernel/user
boundaries currently used by RCU for its userspace extended

We need to pull this up from RCU into this new level of indirection

account_system_vtime() can be called from random places:

Rename it to the even more generic account_vtime() name,

If we want to stop the tick further idle, we need to be

Virtual based cputime accounting solves that problem by

However implementing CONFIG_VIRT_CPU_ACCOUNTING requires

Allow to dynamically switch between tick and virtual based cputime accounting.
This way we can provide a kind of on-demand virtual based cputime

The majority of the DMI checks in efifb are for cases where the bootloader

may do more harm than good due to configuration differences between machines
with the same machine identifier. It turns out that it's possible for

migrate_pages() can return positive value while at the same time emptying

An Andre To Remember

migrate_pages() should return number of pages not migrated or error code.
When unmap_and_move return -EAGAIN, outer loop is re-execution without
initialising nr_failed. This makes nr_failed over-counted.
So this patch correct it by initialising nr_failed in outer loop.
migrate_huge_pages() is
do_migrate_pages() can return the number of pages not migrated.
Because migrate_pages() syscall return this value directly,
migrate_pages() syscall may return the number of pages not migrated.
In fail case in migrate_pages() syscall, we should return error value.
So change err to -EBUSY
move_pages() syscall may return success in case that
do_move_page_to_node_array return positive value which means migration failed.
This patch changes return value of do_move_page_to_node_array
for not returning positive value. It can fix the problem.
