Replace spaces with tabs for indentation to fix the checkpatch.pl warning
'WARNING: please, no spaces at the start of a line'
checkpatch doesn't catch comments indented by spaces but I fixed comments
adjacent to warnings as well so they would remain aligned.

Used C89 instead of C99 Comments and removed C99 comments performing
prints only.

Replace spaces with tabs for indentation to fix the checkpatch.pl warning
'WARNING: please, no spaces at the start of a line'
checkpatch doesn't catch comments indented by spaces but I fixed comments
adjacent to warnings as well so they would remain aligned.
Changes since v1:
fix alignment in
The presence of comments originally caused the two lines
to be over 80 characters long.
The issue is fixed by moving the comments into a separate line.

Some (admittedly odd) irqchips perform functions that are not directly
related to any of their child IRQ lines, and therefore need to perform
some tasks during suspend/resume regardless of whether there are
any "installed" interrupts for the irqchip. However, the current
generic-chip framework
Make use of the new irq_chip chip_{suspend,resume} callbacks.
This is required because if there are no installed child IRQs for
this chip, the irq_{suspend,resume} functions will not be called.
However, we still need to save/restore the forwarding mask, to enable
the top-level GIC interrupt;

The "new_len > old_len" branch in vma_to_resize() looks very confusing.
It only covers the VM_DONTEXPAND/pgoff checks but everything below is
equally unneeded if new_len == old_len.
Change this code to return if "new_len == old_len", new_len < old_len
is not possible, otherwise the code below is
Minor, but this check is overcomplicated. Two half-intervals do NOT
overlap if END1 <= START2 || END2 <= START1, mremap_to() just needs
to negate this check.

move_vma() sets *locked even if move_page_tables() or ->mremap()
fails, change sys_mremap() to check "ret & ~PAGE_MASK".
I think we should simply remove the VM_LOCKED code in move_vma(),
that is why this patch doesn't change move_vma(). But this needs
more cleanups.
Signed-off-by: Oleg Nesterov
move_vma() can't just return if f_op->mremap() fails, we should
unmap the new vma like we do if move_page_tables() fails. To avoid
the code duplication this patch moves the "move entries back" under
the new "if (err)" branch.

The kernel initializes CPU & memory's NUMA topology from ACPI
SRAT table. Some other ACPI tables, such as NFIT and DMAR, also
contain proximity IDs for their device's NUMA topology. This
information can be used to improve performance of these devices.

I believe you need to have error handling here, not because it will
actually fail but to handle deferrals.

If I sit in a loop and do write()s to small tmpfs files,
__sb_end_write() is third-hottest kernel function due to its
smp_mb().
The stated purpose for the smp_mb() in __sb_end_write() is to
ensure "s_writers are updated before we wake up waiters". We
only wake up waiters if waitqueue_active(),
Currently, __sb_start_write() and freeze_super() can race with
each other. __sb_start_write() uses a smp_mb() to ensure that
freeze_super() can see its write to sb->s_writers.counter and
that it can see freeze_super()'s update to sb->s_writers.frozen.
This all seems to work fine.
But, this

PCI BARs tell us whether prefetching is safe, but they don't say anything
about write combining (WC). WC changes ordering rules and allows writes to
be collapsed, so it's not safe in general to use it on a prefetchable
region.
Add pci_iomap_wc() and

The driver doesn't use mtrr_add() or arch_phys_wc_add() but
since we know the framebuffer is isolated already on an
ioremap() we can take advantage of write combining for
performance where possible.
In this case there are a few motivations for this:

OK, the box I'm running this on is using v4.0.5, can you make a patch
based on that, as whatever you make needs to go to stable as well.

This lets drivers take advantage of PAT when available. This

The thread-stack represents a thread's current stack. When a thread
exits there can still be many functions on the stack e.g. exit() can be
called many levels deep, so all the callers will never return. To get
that information output, the thread-stack must be flushed.
