The main intention of the max_segment argument to
__sg_alloc_table_from_pages() is to match the DMA layer segment size set
by dma_set_max_seg_size().

Restricting the input to be page aligned makes it impossible to just
connect the DMA layer to this API.

The only reason for a page alignment here is because the algorithm will
overshoot the max_segment if it is not a multiple of PAGE_SIZE. Simply fix
the alignment before starting and don't expose this implementation detail
to the callers.

A future patch will completely remove SCATTERLIST_MAX_SEGMENT.

From Maor Gottlieb says:

====================
This series extends __sg_alloc_table_from_pages to allow chaining of new
pages to an already initialized SG table.

This allows for drivers to utilize the optimization of merging contiguous
pages without a need to pre allocate all the pages and hold them in a very
large temporary buffer prior to the call to SG table initialization.

The last patch changes the Infiniband core to use the new API. It removes
duplicate functionality from the code and benefits from the optimization
of allocating dynamic SG table from pages.

In huge pages system of 2MB page size, without this change, the SG table
would contain x512 SG entries.

Fix a bug in rxe_rcv() that causes all multicast packets to be
dropped. Currently rxe_match_dgid() is called for each packet to verify
that the destination IP address matches one of the entries in the port
source GID table. This is incorrect for IP multicast addresses since they
do not appear in the GID table.

Add code to detect multicast addresses.

Change function name to rxe_chk_dgid() which is clearer.

The changes referenced below replaced sbk_clone)_ by taking additional
references, passing the skb along and then freeing the skb. This
deleted the packets before they could be processed and additionally
passed bad data in each packet. Since pkt is stored in skb->cb
changing pkt->qp changed it for all the packets.

Replace skb_get() by sbk_clone() in rxe_rcv_mcast_pkt() for cases where
multiple QPs are receiving multicast packets on the same address.

Delete kfree_skb() because the packets need to live until they have been
processed by each QP. They are freed later.

Extend __sg_alloc_table_from_pages to support dynamic allocation of
SG table from pages. It should be used by drivers that can't supply
all the pages at one time.

This function returns the last populated SGE in the table. Users should
pass it as an argument to the function from the second call and forward.
As before, nents will be equal to the number of populated SGEs (chunks).

With this new extension, drivers can benefit the optimization of merging
contiguous pages without a need to allocate all pages in advance and
hold them in a large buffer.

E.g. with the Infiniband driver that allocates a single page for hold the
pages. For 1TB memory registration, the temporary buffer would consume only
4KB, instead of 2GB.

memalloc_nocma_{save/restore} APIs can be used to skip page allocation
on CMA area, but, there is a missing case and the page on CMA area could
be allocated even if APIs are used.  This patch handles this case to fix
the potential issue.

For now, these APIs are used to prevent long-term pinning on the CMA
page.  When the long-term pinning is requested on the CMA page, it is
migrated to the non-CMA page before pinning.  This non-CMA page is
allocated by using memalloc_nocma_{save/restore} APIs.  If APIs doesn't
work as intended, the CMA page is allocated and it is pinned for a long
time.  This long-term pin for the CMA page causes cma_alloc() failure
and it could result in wrong behaviour on the device driver who uses the
cma_alloc().

Missing case is an allocation from the pcplist.  MIGRATE_MOVABLE pcplist
could have the pages on CMA area so we need to skip it if ALLOC_CMA
isn't specified.

The routine that applies debug flags to the kmem_cache slabs
inadvertantly prevents non-debug flags from being applied to those
same objects.  That is, if slub_debug=<flag>,<slab> is specified,
non-debugged slabs will end up having flags of zero, and the slabs
may be unusable.

Fix this by including the input flags for non-matching slabs with the
contents of slub_debug, so that the caches are created as expected
alongside any debugging options that may be requested.  With this, we
can remove the check for a NULL slub_debug_string, since it's covered
by the loop itself.

KVM/arm64 fixes for 5.9, take #3

- Fix synchronization of VTTBR update on TLB invalidation for nVHE systems

The PFEC_MASK and PFEC_MATCH fields in the VMCS reverse the meaning of
the #PF intercept bit in the exception bitmap when they do not match.
This means that, if PFEC_MASK and/or PFEC_MATCH are set, the
hypervisor can get a vmexit for #PF exceptions even when the
corresponding bit is clear in the exception bitmap.

This is unexpected and is promptly detected by a WARN_ON_ONCE.
To fix it, reset PFEC_MASK and PFEC_MATCH when the #PF intercept
is disabled (as is common with enable_ept && !allow_smaller_maxphyaddr).

simply keeping the __latent_entropy attribute on the variable definition
was the correct fix.
