From: Dany Madden <[email protected]>
[ Upstream commit 18f141bf97d42f65abfdf17fd93fb3a0dac100e7 ]
When ibmvnic fails to reset, it breaks out of the reset loop and frees
all of the remaining resets from the workqueue. Doing so prevents the
adapter from recovering if no reset is scheduled after that. Instead,
have the driver continue to process resets on the workqueue.
Remove the no longer need free_all_rwi().

[ Upstream commit 04516706bb99889986ddfa3a769ed50d2dc7ac13 ]
When we read device memory, we lock a spinlock, write the address we
want to read from the device and then spin in a loop reading the data
in 32-bit quantities from another register.
As the description makes clear, this is rather inefficient, incurring
a PCIe bus transaction for every read. In a typical device today, we
want to read 786k SMEM if it crashes, leading to 192k register reads.
Occasionally, we've seen the whole loop take over 20 seconds and then
triggering the soft lockup detector.
Clearly, it is unreasonable to spin here for such extended periods of
time.
To fix this, break the loop down into an outer and an inner loop, and
break out of the inner loop if more than half a second elapsed. To
avoid too much overhead, check for that only every 128 reads, though
there's no particular reason for that number. Then, unlock and relock
to obtain NIC access again, reprogram the start address and continue.
This will keep (interrupt) latencies on the CPU down to a reasonable
time.

[ Upstream commit c5cbfc87558168ef4c3c27ce36eba6b83391db19 ]
The batadv net_device is trying to propagate the needed_headroom and
needed_tailroom from the lower devices. This is needed to avoid cost
intensive reallocations using pskb_expand_head during the transmission.
But the fragmentation code split the skb's without adding extra room at the
end/beginning of the various fragments. This reduced the performance of
transmissions over complex scenarios (batadv on vxlan on wireguard) because
the lower devices had to perform the reallocations at least once.

In the error path of ip_vs_control_net_init(), remove_proc_entry() needs
to be called to remove the added proc entry, otherwise a memory leak
will occur.
Also, add some '#ifdef CONFIG_PROC_FS' because proc_create_net* return NULL
when PROC is not used.

VHOST_IOTLB to make them be built.
However, if VHOST_IOTLB is the only VHOST symbol that is

drivers/Makefile won't descend into drivers/vhost/ to build it,
so make drivers/Makefile build the needed binary whenever
VHOST_IOTLB is set, like it does for VHOST_RING.

[ Upstream commit 4ca23e2c2074465bff55ea14221175fecdf63c5f ]
If a batman-adv packets has to be fragmented, then the original batman-adv
packet header is not stripped away. Instead, only a new header is added in
front of the packet after it was split.
This size must be considered to avoid cost intensive reallocations during
the transmission through the various device layers.

Inconsistent login with the vnicserver is causing the device to be
removed. This does not give the device a chance to recover from error
state. This patch schedules a FATAL reset instead to bring the adapter
up.

commit e91d8d78237de8d7120c320b3645b7100848f24d upstream.
While I was doing zram testing, I found sometimes decompression failed
since the compression buffer was corrupted. With investigation, I found
below commit calls cond_resched unconditionally so it could make a
problem in atomic context if the task is reschedule.

We can fix this by removing the ZSMALLOC_PGTABLE_MAPPING feature (which
contains the offending calling code) from zsmalloc.
Even though this option showed some amount improvement(e.g., 30%) in
some arm32 platforms, it has been headache to maintain since it have
abused APIs[1](e.g., unmap_kernel_range in atomic context).
Since we are approaching to deprecate 32bit machines and already made
the config option available for only builtin build since v5.8, lastly it
has been not default option in zsmalloc, it's time to drop the option
for better maintenance.

commit b8a9092330da2030496ff357272f342eb970d51b upstream.
Clang's integrated assembler produces the warning for assembly files:
warning: DWARF2 only supports one section per compilation unit
If -Wa,-gdwarf-* is unspecified, then debug info is not emitted for
assembly sources (it is still emitted for C sources). This will be
re-enabled for newer DWARF versions in a follow up patch.
Enables defconfig+CONFIG_DEBUG_INFO to build cleanly with
LLVM=1 LLVM_IAS=1 for x86_64 and arm64.

commit 29ac40cbed2bc06fa218ca25d7f5e280d3d08a25 upstream.
The PAT bit is in different locations for 4k and 2M/1G page table
entries.
Add a definition for _PAGE_LARGE_CACHE_MASK to represent the three
caching bits (PWT, PCD, PAT), similar to _PAGE_CACHE_MASK for 4k pages,
and use it in the definition of PMD_FLAGS_DEC_WP to get the correct PAT
index for write-protected pages.

[ Upstream commit 44cef0c0ffbd8d61143712ce874be68a273b7884 ]
In the error handling in c_can_power_up(), there are two bugs:
1) c_can_pm_runtime_get_sync() will increase usage counter if device is not
empty. Forgetting to call c_can_pm_runtime_put_sync() will result in a
reference leak here.
2) c_can_reset_ram() operation will set start bit when enable is true. We
should clear it in the error handling.
We fix it by adding c_can_pm_runtime_put_sync() for 1), and
c_can_reset_ram(enable is false) for 2) in the error handling.

get a completion timeout in the firmware. Change the LTR configuration
to avoid that. The firmware will do some more complex reinit of this

During CSA, we briefly nullify the phy context, in __iwl_mvm_unassign_vif_chanctx.
In case we have a FW assert right after it, it remains NULL though.
We end up running into endless loop due to mac80211 trying repeatedly to
move us to ASSOC state, and we keep returning -EINVAL. Later down the road
we hit a kernel panic.

The SDIO recheck fix is required for more of the supported variants. Let's
add it to those that needs it.

[ Upstream commit 992b03b88e36254e26e9a4977ab948683e21bd9f ]
When a packet is fragmented by batman-adv, the original batman-adv header
is not modified. Only a new fragmentation is inserted between the original
one and the ethernet header. The code must therefore make sure that it has
a writable region of this size in the skbuff head.
But it is not useful to always reallocate the skbuff by this size even when
there would be more than enough headroom still in the skb. The reallocation
is just to costly during in this codepath.

[ Upstream commit 568d3434178b00274615190a19d29c3d235b4e6d ]
The NO_160 flag specifies if the device doesn't have 160 MHz support,
but we errorneously assumed the opposite. If the flag was set, we
were considering that 160 MHz was supported, but it's actually the
opposite. Fix it by inverting the bits, i.e. NO_160 is 0x1 and 160
is 0x0.
