TLB dropins require updates to the CBR instruction istatus field. This is
needed to resolve race conditions in the chip.
The code currently uses the user address of the CBR. This works but opens
up additional endcases related to stealing of contexts and accessing the
CBR from tasks that do not have access to the user address space. (Some
of this non-user task access is debug code that is not currently being
pushed to the community).
User CBRs are also directly accessible using the kernel mapping of the
CBR. Change the TLB dropin code to use the the kernel mapping of the CBR.

This was a difficult bug to trip. XPC was in the middle of sending an
acknowledgement for a received message.
In xpc_received_payload_uv():
.
ret = xpc_send_gru_msg(ch->sn.uv.cached_notify_gru_mq_desc, msg,
sizeof(struct xpc_notify_mq_msghdr_uv));
if (ret != xpSuccess)
XPC_DEACTIVATE_PARTITION(&xpc_partitions[ch->partid], ret);
msg->hdr.msg_slot_number += ch->remote_nentries;
at the point in xpc_send_gru_msg() where the hardware has dispatched the
acknowledgement, the remote side is able to reuse the message structure
and send a message with a different slot number. This problem is made
worse by interrupts.
The adjustment of msg_slot_number and the BUG_ON in
xpc_handle_notify_mq_msg_uv() which verifies the msg_slot_number is
consistent are only used for debug purposes. Since a fix for this that
preserves the debug functionality would either have to infringe upon the
payload or allocate another structure just for debug, I decided to remove
it entirely.

The UV BIOS has moved the location of some of their pointers to the

Additionally, the BIOS call for registering a message queue watchlist has

Addscrubbing to the i5100 chipset. The i5100 chipset only supports one
scrubbing rate, which is not constant but dependent on memory load. The
rate returned by this driver is an estimate based on some experimentation,
but is substantially closer to the truth than the speed supplied in the
documentation.
Also, scrubbing is done once, and then a done-bit is set. This means that
to accomplish continuous scrubbing a re-enabling mechanism must be used.
I have created the simplest possible such mechanism in the form of a
work-queue which will check every five minutes. This interval is quite
arbitrary but should be sufficient for all sizes of system memory.

The intelfb driver sets color map depending on currently active pipe.
However, if an LVDS display is attached (like in laptop) the active pipe
variable is never set. The default value is PIPE_A and can be wrong. Set
up the pipe variable during driver initialization after hardware state was
read.
Also, the detection of the active display (and hence the pipe) is wrong.
The pipes are assigned to so called planes. Both pipes are always enabled
on my laptop but only one plane is enabled (the plane A for the CRT or the
plane B for the LVDS). Change active pipe detection code to take into
account a status of the plane assigned to each pipe.
The problem is visible in the 8 bpp mode if colors above 15 are used. The
first 16 color entries are displayed correctly.

The rtc-omap driver currently assumes that the rtc's registers are at a
fixed address and already mapped into virtual memory space. Remove those
assumptions so the same driver can be used for similar devices that reside
at different physical addresses (e.g., TI's DA8xx/OMAP-L13x SoC's).
Also allow the possibility for the timer and alarm interrupts to use the
same IRQ.

Add setting and clearing of the "pending" flag of the RTC alarm. The
semantics follow the UEFI specification 2.2 available at

disabling the alarm, but not by any other condition (such as the passing
of time, a successful wakeup, or setting of a new alarm.)

Now that we've removed the BKL here, let's explicitly set llseek to
no_llseek since the default llseek is not used here.
The default_llseek function still contains the BKL. When we are auditing
code to see if we can remove the BKL, this is one of the hidden
considerations we need to take into account. i.e., is there
syncronization between code that has the BKL and llseek.
At the same time we remove the BKL it would be a good idea to do indicate
when no llseek function is required, so we don't have to revisit this code
again, when we are trying to determine if we can remove the BKL from the
default_llseek.

I noticed that rtc wont generate interrupts after a resume from disk.
Here hpet rtc emulation is used.
Problem is that rtc hpet comparator, isn't reinitialized after resume.
Easiest way to solve this, is always mask all hpet interrupts on suspend
This is triggered, when suspending with alarm set.
Otherwise, hpet driver will think it doesn't need to reinitialize
the rtc comparator, thus rtc interrupts won't work.
This emulation isn't need for wakealarm.

Fix node-oriented allocation handling in oom-kill.c I myself think of this
as a bugfix not as an ehnancement.
In these days, things are changed as
- alloc_pages() eats nodemask as its arguments, __alloc_pages_nodemask().
- mempolicy don't maintain its own private zonelists.
(And cpuset doesn't use nodemask for __alloc_pages_nodemask())
So, current oom-killer's check function is wrong.
This patch does
- check nodemask, if nodemask && nodemask doesn't cover all
node_states[N_HIGH_MEMORY], this is CONSTRAINT_MEMORY_POLICY.
- Scan all zonelist under nodemask, if it hits cpuset's wall
this faiulre is from cpuset.
And
- modifies the caller of out_of_memory not to call oom if __GFP_THISNODE.
This doesn't change "current" behavior. If callers use __GFP_THISNODE
it should handle "page allocation failure" by itself.
- handle __GFP_NOFAIL+__GFP_THISNODE path.
This is something like a FIXME but this gfpmask is not used now.
