[Flang][OpenMP] Initial defaultmap implementation (#135226)
This aims to implement most of the initial arguments for defaultmap
aside from firstprivate and none, and some of the more recent OpenMP 6
additions which will come in subsequent updates (with the OpenMP 6
variants needing parsing/semantic support first).
vm-design: Remove reference to page coloring
Page coloring was not implemented in the new physical memory allocator
in commit 11752d88a23c.
Also add a note that this doc is outdated.

[MLIR][XeGPU] Add unroll patterns for XeGPU (1/N) (#137010)
Similar to vector ops, XeGPU ops need to be unrolled into smaller shapes
such that they can be dispatched into a hardware instruction. This PR
marks the initial phase of a series dedicated to incorporating unroll
patterns for XeGPU operations. In this installment, we introduce
patterns for the following operations:
1. createNd
2. updateNd
3. prefetchNd
4. loadNd
5. storeNd
6. dpas

linuxkpi: Fix up jiffies handling
A few issues found by code inspection while hunting for bugzilla PR
286512:
- The "expires" field in struct delayed_work should be unsigned.
- In linux_timer_jiffies_until(), clamp the return value to INT_MAX:
this return value is used as a ticks count, not a jiffies count, so we
should avoid returning too large a value, lest it get truncated. It's
unlikely we are dealing with values that large, but we should be
careful anyway.
- In linux_add_to_sleepqueue(), truncate the timeout to INT_MAX, as this
value is passed to sleepq_set_timeout() as a ticks value. Typically
it's multiplied by ticks_sbt to get an sbintime, and we should make
sure the multiplication doesn't overflow. In drm-kmod, there is at
least one call mod_delayed_work(... MAX_SCHEDULE_TIMEOUT).

[libclc] Move tan to the CLC library (#139547)
There was already a __clc_tan in the OpenCL layer. This commit moves the
function over whilst vectorizing it.
The function __clc_tan is no longer a public symbol, which should have
never been the case.
AMDGPU: Use minimumnum/maximumnum for fmed3 with amdgpu-ieee=0
Try to respect the signaling nan behavior of the instruction,
so also start the special case fold for src2.
