This is a question about tradeoffs. I'm playing with a couple of
approaches for an x86 seccomp fast path.
It looks like populating struct seccomp_data in the syscall entry asm
code saves 4-5ns (83ns vs 87.7ns or so for getpid with seccomp
enabled). Presumably this is because it avoids a branch a
This function always returns 1, thus no need to check return value
in hugetlb_cow(). By doing so, we can get rid of the unnecessary WARN_ON
call. While this logic perhaps existed as a way of identifying future
unmap_ref_private() mishandling, reality is it serves no apparent purpose.

When returning from hugetlb_cow(), we always (1) put back the refcount
for each referenced page -- always 'old', and 'new' if allocation was
successful. And (2) retake the page table lock right before returning,
as the callers expects. This logic can be simplified and encapsulated,
as proposed in t

Hm, this is defined in mm.h and we include it via drmP.h, which is

Several platforms use a rather generic version of parsing
the device tree to find the host bridge ranges. Move the common code
into the generic PCI code and use it to create a pci_host_bridge

Hi all,
This series fixes a probe order issue with the Tegra EHCI driver.
Basically, the register area of the 1st USB controller contains some
registers that are global to all of the controllers, but that are also
cleared when reset is asserted to the 1st controller. So if (say) the
3rd controller
tegra_usb_phy_close() is supposed to undo the effects of
tegra_usb_phy_init(). It is also currently added as the USB PHY shutdown
callback, which is wrong, since tegra_usb_phy_init() is only called
during probing wheras the shutdown callback can get called multiple
times. This then leads to warning

Avoid matching allocs that appear to be known
small multiplications of a sizeof with a constant
because gcc as of 4.8 cannot optimize the code in
a calloc() exactly the same way as an alloc().
Look for numeric constants or what appear to be

Hi all,
While fuzzing with trinity inside a KVM tools guest running the latest -next
kernel I've stumbled on the following spew:
[ 1307.646561] kernel BUG at net/core/skbuff.c:99!
[ 1307.647152] invalid opcode: [#1] PREEMPT SMP DEBUG_PAGEALLOC
[ 1307.648080] Dumping ftrace buffer:
[ 1307.648
So I am wondering them should I can it to sizeof(appleir_keymap)?

Qualifying the pointer as const would be even more explicit.
