f946a5ec96 linuxkpi: dma_get_cache_alignment(): Fix off-by-one result
Substituting 'uma_align_cache' by the appropriately named accessor
uma_get_cache_align_mask() made apparent that dma_get_cache_alignment()
was off by one, since it was defined to be the mask derived from the
alignment value.

4587326893 uma: Hide 'uma_align_cache'; Create/rename accessors
Create the uma_get_cache_align_mask() accessor and put it in a separate
private header so as to minimize namespace pollution in header/source
files that need only this function and not the whole 'uma.h' header.

Make sure the accessors have '_mask' as a suffix, so that callers are
aware that the real alignment is the power of two that is the mask plus
one.  Rename the stem to something more explicit.  Rename
uma_set_cache_align_mask()'s single parameter to 'mask'.

Hide 'uma_align_cache' to ensure that it cannot be set in any other way
then by a call to uma_set_cache_align_mask(), which will perform sanity
checks in a further commit.  While here, rename it to
'uma_cache_align_mask'.

This is also in preparation for some further changes, such as improving
the sanity checks, eliminating internal resolving of UMA_ALIGN_CACHE and
changing the type of the 'uma_cache_align_mask' variable.

8614ae463a LinuxKPI: 802.11: adjust code to new structure layout
With past commits new structures were added.  Now switch over some
bss_conf fields into vif->cfg where they got moved to and remove the
old fields.  This allows drivers to find the expected values in the
now expected places and work better.

82782cffea LinuxKPI: 802.11: prepare for iwlwifi driver updates
Update ieee80211_request_smps() to the new number of arguments in
LinuxKPI (which was already prepared) and update the one call in the
older iwlwifi driver version.
This will allow iwlwifi as-is now and rtw88 to compile in case someone
else wants to work on the latter in parallel to predominant efforts on
the former.

Unconditionally enable the other changes for newer drivers, as needed by
iwlwifi (and others).

2709483a72 linuxkpi: fix iteration in __sg_alloc_table_from_pages
Commit 3f686532c9 tried to fix an issue with not properly starting
at the first page in the sg list to prevent a panic. This worked but
with the side effect of incrementing "s" during the final iteration
causing it to be NULL since the list had ended.
In cases non-DEBUG kernels this causes a panic with drm-5.15, since
"s" is NULL when we later pass it to sg_mark_end().
This change decouples the iteration sg from the return value so that
it is never incremented past the final page in the chain.
