During tear down (e.g. mwifiex_sdio_remove during system suspend),
mwifiex left IRQs enabled for a significant period of time when it was
unable to handle them correctly. This caused interrupt storms and
interfered with the bluetooth interface on the same SDIO card.
Solve this by disabling interrupts at the point when they can no longer
be handled correctly, which is at the start of mwifiex_remove_card().
For cleanliness, we now enable interrupts in the mwifiex_add_card() path,
to be symmetrical with the disabling of interrupts. We also couple the
registration of the sdio IRQ handler with the actual enable/disable of
interrupts at the hardware level.
I also removed a write to this register in mwifiex_init_sdio which seemed
pointless and won't cause any ill effects now that we only register
the SDIO IRQ handler when we are ready to accept interrupts.

Noticed that my old Radeon 7500 hung after printing
drm: GPU not posted. posting now...
when it wasn't selected as the primary card the BIOS. Some digging
revealed that it was hanging in combios_parse_mmio_table() while
parsing the ASIC INIT 3 table. Looking at the BIOS ROM for the card,
it becomes obvious that there is no ASIC INIT 3 table in the BIOS.
The code is just processing random garbage. No surprise it hangs!
Why do I say that there is no ASIC INIT 3 table is the BIOS? This
table is found through the MISC INFO table. The MISC INFO table can
be found at offset 0x5e in the COMBIOS header. But the header is
smaller than that. The COMBIOS header starts at offset 0x126. The
standard PCI Data Structure (the bit that starts with 'PCIR') lives at
offset 0x180. That means that the COMBIOS header can not be larger
than 0x5a bytes and therefore cannot contain a MISC INFO table.
I looked at a dozen or so BIOS images, some my own, some downloaded from:
<http://www.techpowerup.com/vgabios/index.php?manufacturer=ATI&page=1>
It is fairly obvious that the size of the COMBIOS header can be found
at offset 0x6 of the header. Not sure if it is a 16-bit number or
just an 8-bit number, but that doesn't really matter since the tables
seems to be always smaller than 256 bytes.
So I think combios_get_table_offset() should check if the requested
table is present. This can be done by checking the offset against the
size of the header. See the diff below. The diff is against the WIP
OpenBSD codebase that roughly corresponds to Linux 3.8.13 at this
point. But I don't think this bit of the code changed much since
then.

This reverts commit 8af6c08830.
This patch re-adds the workaround introduced by 596264082f
which was reverted by 8af6c08830.
The original patch 596264 was needed to overcome a situation where
the hid-core would drop incoming reports while probe() was being
executed.
This issue was solved by c849a6143b which added
hid_device_io_start() and hid_device_io_stop() that enable a specific
hid driver to opt-in for input reports while its probe() is being
executed.
Commit a9dd22b730 modified hid-logitech-dj so as to use the
functionality added to hid-core. Having done that, workaround 596264
was no longer necessary and was reverted by 8af6c08.
We now encounter a different problem that ends up 'again' thwarting
the Unifying receiver enumeration. The problem is time and usb controller
dependent. Ocasionally the reports sent to the usb receiver to start
the paired devices enumeration fail with -EPIPE and the receiver never
gets to enumerate the paired devices.
With dcd9006b1b the problem was "hidden" as the call to the usb
driver became asynchronous and none was catching the error from the
failing URB.
As the root cause for this failing SET_REPORT is not understood yet,
-possibly a race on the usb controller drivers or a problem with the
Unifying receiver- reintroducing this workaround solves the problem.
Overall what this workaround does is: If an input report from an
unknown device is received, then a (re)enumeration is performed.

This patch is intended to avoid the buffering to non-assoc mesh STA
and also to avoid the triggering of frame to non-assoc mesh STA which
could cause kernel panic in specific hw.
One of the examples, is kernel panic happens to ath9k if user space
inserts the mesh STA and not proceed with the SAE and AMPE, and later
the same mesh STA is detected again. The sta_state of the mesh STA remains
at IEEE80211_STA_NONE and if the ieee80211_sta_ps_deliver_wakeup is called
and subsequently the ath_tx_aggr_wakeup, the kernel panic due to
ath_tx_node_init is not called before to initialize the require data
structures.
This issue is reported by Cedric Voncken before.

When map_lowmem() runs, and processes a memory bank whose start or end
is not section-aligned, memory must be allocated to store the 2nd-level
page tables. Those allocations are made by calling memblock_alloc().
At this point, the only memory that is free *and* mapped is memory which
has already been mapped by map_lowmem() itself. For this reason, we must
calculate the first point at which map_lowmem() will need to allocate
memory, and set the memblock allocation limit to a lower address, so that
memblock_alloc() is guaranteed to return memory that is already mapped.
This patch enhances sanity_check_meminfo() to calculate that memory
address, and pass it to memblock_set_current_limit(), rather than just
assuming the limit is arm_lowmem_limit.
The algorithm applied is:
* Default memblock_limit to arm_lowmem_limit in the absence of any other
limit; arm_lowmem_limit is the highest memory that is mapped by
map_lowmem().
* While walking the list of memblocks, if the start of a block is not
aligned, 2nd-level page tables will need to be allocated to map the
first few pages of the block. Hence, the memblock_limit must be before
the start of the block.
* Similarly, if the end of any block is not aligned, 2nd-level page
tables will need to be allocated to map the last few pages of the
block. Hence, the memblock_limit must point at the end of the block,
rounded down to section-alignment.
* The memory blocks are assumed to be sorted in address order, so the
first unaligned block start or end is used to set the limit.
With this algorithm, the start or end of almost any bank can be non-
section-aligned. The only exception is that the start of bank 0 must
be section-aligned, since otherwise memory would need to be allocated
when mapping the start of bank 0, which occurs before any free memory
is mapped.

However, here we have a case in point: developers don't understand the
option either, as they were thinking that when the option is not set,
the decompressor should produce no output what so ever. This is
incorrect, as the purpose of this option is to control whether a

output or not.
So let's document this via help rather than commentry to prevent others

- fixup panel fitter readout for gen2/3 (just quitens dmesg noise)
- fix pft computations for non-autoscaled resolutions (i.e. letter/pillar
boxing on gen2/3)
- preserve the DDI A/E lane sharing bit (Stéphane Marchesin)
- fix the "rc6 fails to work after resume" regression, big thanks to
Konstantin Khlebnikov for the patch and debug insight about what
actually might be going on here
- fix Oops in is_crtc_connector_off (Chris)
- sanitize shared dpll state - our new paranoid state checker tripped up
over dirt left behind by the BIOS
- correctly restore fences, fixes the "my screen is all messed up after
resume" regression introduced in the final 3.10 pull request
- quirk backlights harder, this time for Dell XPS13 machines to fix a
regression (patch from Kamal Mostafa)
- 90% fix for some haswell hangs when accessing registers concurrently,
the 100% solution is simply too invasive for -fixes and what we have
here seems to be good enough (Chris)

Commit f1a18a105 "Thermal: CPU Package temperature thermal" had code
that did a get_online_cpus(), run a loop and then do a
put_online_cpus(). The problem is that the loop had an error exit that
would skip the put_online_cpus() part.
In the error exit part of the function, it also did a get_online_cpus(),
run a loop and then put_online_cpus(). The only way to get to the error
exit part is with get_online_cpus() already performed. If this error
condition is hit, the system will be prevented from taking CPUs offline.
The process taking the CPU offline will lock up hard.
Removing the get_online_cpus() removes the lockup as the hotplug CPU
refcount is back to zero.
This was bisected with ktest.
