4d95f99c59 brcmfmac: Add DMI nvram filename quirk for PoV TAB-P1006W-232 tablet
The Point of View TAB-P1006W-232 tablet contains quite generic names in
the sys_vendor and product_name DMI strings, without this patch brcmfmac
will try to load: brcmfmac43340-sdio.Insyde-BayTrail.txt as nvram file
which is a bit too generic.

Add a DMI quirk so that a unique and clearly identifiable nvram file
name is used on the PoV TAB-P1006W-232 tablet.

72255c8071 ray_cs: fix array out-of-bounds access
Currently array element org[3] is being accessed, however the array is
only 3 elements in size, so this looks like an off-by-one out-of-bounds
error. Fix this by using org[2], which I believe was the original
intent.

This issue has existed in the driver back in the pre-git days, so no
idea when it was introduced.

ba42273131 mm/mmu_notifier: mm/rmap.c: Fix a mmu_notifier range bug in try_to_unmap_one
The conversion to use a structure for mmu_notifier_invalidate_range_*()
unintentionally changed the usage in try_to_unmap_one() to init the
'struct mmu_notifier_range' with vma->vm_start instead of @address,
i.e. it invalidates the wrong address range.  Revert to the correct
address range.

Manifests as KVM use-after-free WARNINGs and subsequent "BUG: Bad page
state in process X" errors when reclaiming from a KVM guest due to KVM
removing the wrong pages from its own mappings.

d78a600f70 drm/i915: drop DPF code for gen8+
The only gen8+ platform that has the feature is BDW, but we don't define
the feature flag on any BDW platform and we only have partial support in
the gen8 path (irq enabling code, but no handler).
The only thing we could do in the irq handler is report the error
to userspace, but no one asked/cared about that since BDW was
released so it is relatively safe to assume that even if we added the
message no one would look at it. Just drop the dead code from the
driver instead.

6dce603632 ARM: davinci: sffsdr: fix the at24 eeprom device name
The currently used 24lc64 i2c device name doesn't match against any
of the devices supported by the at24 driver. Change it to the closest
compatible chip.

71be581181 ARM: davinci: dm646x-evm: use device properties for at24 eeprom
We want to work towards phasing out the at24_platform_data structure.
There are few users and its contents can be represented using generic
device properties. Using device properties only will allow us to
significantly simplify the at24 configuration code.

Remove the at24_platform_data structure and replace it with an array
of property entries. Drop the byte_len/size property, as the model name
already implies the EEPROM's size.

35e6103861 xfrm: refine validation of template and selector families
The check assumes that in transport mode, the first templates family
must match the address family of the policy selector.

Syzkaller managed to build a template using MODE_ROUTEOPTIMIZATION,
with ipv4-in-ipv6 chain, leading to following splat:

BUG: KASAN: stack-out-of-bounds in xfrm_state_find+0x1db/0x1854
Read of size 4 at addr ffff888063e57aa0 by task a.out/2050
 xfrm_state_find+0x1db/0x1854
 xfrm_tmpl_resolve+0x100/0x1d0
 xfrm_resolve_and_create_bundle+0x108/0x1000 [..]

Problem is that addresses point into flowi4 struct, but xfrm_state_find
treats them as being ipv6 because it uses templ->encap_family is used
(AF_INET6 in case of reproducer) rather than family (AF_INET).

This patch inverts the logic: Enforce 'template family must match
selector' EXCEPT for tunnel and BEET mode.

In BEET and Tunnel mode, xfrm_tmpl_resolve_one will have remote/local
address pointers changed to point at the addresses found in the template,
rather than the flowi ones, so no oob read will occur.
