You can view the current XenServer patch queue at:

https://github.com/xenserver/linux-3.x.pg

There are only two things I would recommend taking but they're not ready
yet.

1. Fix for high MMIO regions.

0001-x86-xen-rename-early_p2m_alloc-and-early_p2m_alloc_m.patch
...
0008-x86-remove-the-Xen-specific-_PAGE_IOMAP-PTE-flag.patch

These require more testing.

2. Preemptible privcmd hypercalls.

The current set of patches is broken and the fixed version is not ready yet.

I also note two fixes for 32-bit guests were not tagged for stable. I
have now asked for these to be added to the stable trees.  These are:

0160676bba69523e8b0ac83f306cce7d342ed7c8 (xen/p2m: check MFN is in range
before using the m2p table)

7cde9b27e7b3a2e09d647bb4f6d94e842698d2d5 (xen: Fix possible user space
selector corruption)
