48aba08e5e arm64: dts: renesas: ulcb: Mark SWDT as reserved

ULCB boards. Sadly, it doesn't mark the node as reserved, so this is
added manually here.

4f9ffd2c80 drm/ttm: add pgprot handling for RISC-V 
The RISC-V Svpbmt privileged extension provides support for overriding
page memory coherency attributes, and, along with vendor extensions like
Xtheadmae, supports pgprot_{writecombine,noncached} on RISC-V.

Adapt the codepath that maps ttm_write_combined to pgprot_writecombine
and ttm_noncached to pgprot_noncached to RISC-V, to allow proper page
access attributes.

503a5e4690 RDMA/rxe: Fix null deref on srq->rq.queue after resize failure 
A NULL pointer dereference can occur in rxe_srq_chk_attr() when
ibv_modify_srq() is invoked twice in succession under certain error
conditions. The first call may fail in rxe_queue_resize(), which leads
rxe_srq_from_attr() to set srq->rq.queue = NULL. The second call then
triggers a crash (null deref) when accessing
srq->rq.queue->buf->index_mask.

7197e080de Merge branch 'xfrm: IPsec hardware offload performance improvements' 
Jianbo Liu says:

====================
This patch series optimizes IPsec crypto offload performance by
addressing a lock contention bottleneck using RSS.

The first patch refactors the xfrm_input to avoid a costly
unlock/relock cycle.

The second patch builds on this by removing a redundant replay check,
which is unnecessary for the synchronous hardware path.

9600156bb9 cpufreq: nforce2: fix reference count leak in nforce2 
There are two reference count leaks in this driver:

1. In nforce2_fsb_read(): pci_get_subsys() increases the reference count
   of the PCI device, but pci_dev_put() is never called to release it,
   thus leaking the reference.

2. In nforce2_detect_chipset(): pci_get_subsys() gets a reference to the
   nforce2_dev which is stored in a global variable, but the reference
   is never released when the module is unloaded.

Fix both by:
- Adding pci_dev_put(nforce2_sub5) in nforce2_fsb_read() after reading
  the configuration.
- Adding pci_dev_put(nforce2_dev) in nforce2_exit() to release the
  global device reference.

Found via static analysis.
