89a2aefe4b xfrm: call xfrm_dev_policy_delete when kill policy 
xfrm_policy_kill() is called at different places to delete xfrm
policy. It will call xfrm_pol_put(). But xfrm_dev_policy_delete() is
not called to free the policy offloaded to hardware.

The three commits cited here are to handle this issue by calling
xfrm_dev_policy_delete() outside xfrm_get_policy(). But they didn't
cover all the cases. An example, which is not handled for now, is
xfrm_policy_insert(). It is called when XFRM_MSG_UPDPOLICY request is
received. Old policy is replaced by new one, but the offloaded policy
is not deleted, so driver doesn't have the chance to release hardware
resources.

To resolve this issue for all cases, move xfrm_dev_policy_delete()
into xfrm_policy_kill(), so the offloaded policy can be deleted from
hardware when it is called, which avoids hardware resources leakage.

Fixes: 919e43fad5 ("xfrm: add an interface to offload policy")
Fixes: bf06fcf4be ("xfrm: add missed call to delete offloaded policies")

9199b915e9 xfrm: fix netdev reference count imbalance 
In cited commit, netdev_tracker_alloc() is called for the newly
allocated xfrm state, but dev_hold() is missed, which causes netdev
reference count imbalance, because netdev_put() is called when the
state is freed in xfrm_dev_state_free(). Fix the issue by replacing
netdev_tracker_alloc() with netdev_hold().

3abbd7ed8b act_ct: prepare for stolen verdict coming from conntrack and nat engine 
At this time, conntrack either returns NF_ACCEPT or NF_DROP.
To improve debuging it would be nice to be able to replace NF_DROP verdict
with NF_DROP_REASON() helper,

This helper releases the skb instantly (so drop_monitor can pinpoint
exact location) and returns NF_STOLEN.

Prepare call sites to deal with this before introducing such changes
in conntrack and nat core.

921c87ba38 mmc: Convert from tasklet to BH workqueue 
The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.

This patch converts drivers/mmc/* from tasklet to BH workqueue.

a1382d193c mmc: mmc_spi: allow for spi controllers incapable of getting as low as 400k 
Some controllers may not be able to reach a bus clock as low as 400 KHz
due to a lack of sufficient divisors. In these cases, the SD card slot
becomes non-functional as Linux continuously attempts to set the bus
clock to 400 KHz. If the controller is incapable of getting that low,
set its minimum frequency instead. While this may eliminate some SD
cards, it allows those capable of operating at the controller's minimum
frequency to be used.

395a02d04e landlock: Use bit-fields for storing handled layer access masks 
When defined using bit-fields, the compiler takes care of packing the
bits in a memory-efficient way and frees us from defining
LANDLOCK_SHIFT_ACCESS_* by hand.  The exact memory layout does not
matter in our use case.

The manual definition of LANDLOCK_SHIFT_ACCESS_* has resulted in bugs in
at least two recent patch sets [1] [2] where new kinds of handled access
rights were introduced.

ebf5a79acf x86/efistub: Drop redundant clearing of BSS 
As it turns out, clearing the BSS was not the right fix for the issue
that was ultimately fixed by commit decd347c2a ("x86/efistub:
Reinstate soft limit for initrd loading"), and given that the Windows
EFI loader becomes very unhappy when entered with garbage in BSS, this
is one thing that x86 PC EFI implementations can be expected to get
right.

So drop it from the pure PE entrypoint. The handover protocol entrypoint
still needs this - it is used by the flaky distro bootloaders that
barely implement PE/COFF at all.

This patch is also applicable for some non T2 Intel Macs.

7b2450bb40 perf dsos: When adding a dso into sorted dsos maintain the sort order 
dsos__add would add at the end of the dso array possibly requiring a
later find to re-sort the array. Patterns of find then add were
becoming O(n*log n) due to the sorts. Change the add routine to be
O(n) rather than O(1) but to maintain the sorted-ness of the dsos
array so that later finds don't need the O(n*log n) sort.

 "A set of clk fixes for the Qualcomm, Mediatek, and Allwinner drivers:

   - Fix the Qualcomm Stromer Plus PLL set_rate() clk_op to explicitly
     set the alpha enable bit and not set bits that don't exist

   - Mark Qualcomm IPQ9574 crypto clks as voted to avoid stuck clk
     warnings

   - Fix the parent of some PLLs on Qualcomm sm6530 so their rate is
     correct

   - Fix the min/max rate clamping logic in the Allwinner driver that
     got broken in v6.9

   - Limit runtime PM enabling in the Mediatek driver to only
     mt8183-mfgcfg so that system wide resume doesn't break on other
     Mediatek SoCs"

58b0afa038 vfs: link_path_walk: improve may_lookup() code generation 
Instead of having separate calls to 'inode_permission()' depending on
whether we're in RCU lookup or not, just share the first call.

Note that the initial "conditional" on LOOKUP_RCU really turns into just
a "convert the LOOKUP_RCU bit in the nameidata into the MAY_NOT_BLOCK
bit in the argument", which is just a trivial bitwise and and shift
operation.

So the initial conditional goes away entirely, and then the likely case
is that it will succeed independently of us being in RCU lookup or not,
and the possible "we may need to fall out of RCU and redo it all" fixups
that are needed afterwards all go in the unlikely path.

[ This also marks 'nd' restrict, because that means that the compiler
  can know that there is no other alias, and can cache the LOOKUP_RCU
  value over the call to inode_permission(). ]

On shared memory CPPC systems, with amd_pstate=active mode, the change
in scaling_max_freq doesn't get written to the shared memory
region. Due to this, the writes to the scaling_max_freq sysfs file
don't take effect. Fix this by propagating the scaling_max_freq
changes to the shared memory region.
