This is the new timerfd API as it is implemented by the following patch:
int timerfd_create(int clockid, int flags);
int timerfd_settime(int ufd, int flags,
const struct itimerspec *utmr,
struct itimerspec *otmr);
int timerfd_gettime(int ufd, struct itimerspec *otmr);
The timerfd_create() API creates an un-programmed timerfd fd. The "clockid"
parameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME.
The timerfd_settime() API give new settings by the timerfd fd, by optionally
retrieving the previous expiration time (in case the "otmr" parameter is not
NULL).
The time value specified in "utmr" is absolute, if the TFD_TIMER_ABSTIME bit
is set in the "flags" parameter. Otherwise it's a relative time.
The timerfd_gettime() API returns the next expiration time of the timer, or
{0, 0} if the timerfd has not been set yet.
Like the previous timerfd API implementation, read(2) and poll(2) are
supported (with the same interface). Here's a simple test program I used to
exercise the new timerfd APIs:

As Roland pointed out, we have the very old problem with exec. de_thread()
sets SIGNAL_GROUP_EXIT, kills other threads, changes ->group_leader and then
clears signal->flags. All signals (even fatal ones) sent in this window
(which is not too small) will be lost.
With this patch exec doesn't abuse SIGNAL_GROUP_EXIT. signal_group_exit(),
the new helper, should be used to detect exit_group() or exec() in progress.
It can have more users, but this patch does only strictly necessary changes.

Every time we set SIGNAL_GROUP_EXIT or clear SIGNAL_STOP_DEQUEUED we also
reset ->group_stop_count.
This means that the SIGNAL_GROUP_EXIT check in handle_group_stop() is not
needed, and do_signal_stop() should check SIGNAL_STOP_DEQUEUED only when
->group_stop_count == 0. With these changes handle_group_stop() becomes the
subset of do_signal_stop(), we can kill it and use do_signal_stop() instead.
Also, a preparation for the next patch.

When __group_complete_signal() sees sig_kernel_coredump() signal, it starts
the group stop, but sets ->group_exit_task = t in a hope that "t" will
actually dequeue this signal and invoke do_coredump(). However, by the
time "t" enters get_signal_to_deliver() it is possible that the signal was
blocked/ignored or we have another pending !SIG_KERNEL_COREDUMP_MASK signal
which will be dequeued first. This means the task could be stopped but not
killed.
Remove this code from __group_complete_signal(). Note also this patch
removes the bogus signal_wake_up(t, 1). This thread can't be
STOPPED/TRACED, note the corresponding check in wants_signal().

Ulrich says that we never used this clone flags and that nothing should be

As we're down to only a single bit left in clone's flags argument, let's add a
warning to check that no userspace is actually using it. Hopefully we will
be able to recycle it.

CLONE_STOPPED was previously used by some NTPL versions when under

This adds support for flushing the chipsets on the 915, 945, 965 and G33
families of Intel chips.
The BIOS doesn't seem to always allocate the BAR on the 965 chipsets
so I have to use pci resource code to create a resource
It adds an export for pcibios_align_resource.
This bumps the AGP interface to 0.103.
Certain Intel chipsets contains a global write buffer, and this can require
flushing from the drm or X.org to make sure all data has hit RAM before
initiating a GPU transfer, due to a lack of coherency with the integrated
graphics device and this buffer.
This just adds generic support to the AGP interfaces, a follow-on patch
will add support to the Intel driver to use this interface.

When a host just goes away (crash, power loss, etc.) without tearing

In mthca_reg_phys_mr(), we calculate the page size for the HCA
hardware to use to map the buffer list passed in by the consumer.
For example, if the consumer passes in
[0] addr 0x1000, size 0x1000
[1] addr 0x2000, size 0x1000
then the algorithm would come up with a page size of 0x2000 and a list
of two pages, at 0x0000 and 0x2000. Usually, this would work fine
since the memory region would start at an offset of 0x1000 and have a
length of 0x2000.
However, the old code did not take into account the alignment of the
IO virtual address passed in. For example, if the consumer passed in
a virtual address of 0x6000 for the above, then the offset of 0x1000
would not be used correctly because the page mask of 0x1fff would
result in an offset of 0.
We can fix this quite neatly by making sure that the page shift we use
is no bigger than the first bit where the start of the first buffer
and the IO virtual address differ. Also, we can further simplify the
code by removing the special case for a single buffer by noticing that
it doesn't matter if we use a page size that is too big. This allows
the loop to compute the page shift to be replaced with __ffs().
