commit 96c9eae638765c2bf2ca4f5a6325484f9bb69aa7 upstream.
For DIO writes, if it is not blocksize aligned, we need to do
internal serialization. It may slow down writers anyway. So we
just bail them out and resend to MDS.

commit f742dc4a32587bff50b13dde9d8894b96851951a upstream.
For DIO read, if it is not sector aligned, we should reject it
and resend via MDS. Otherwise there might be data corruption.
Also teach bl_read_pagelist to handle partial page reads for DIO.

commit 1f2ff682ac951ed82cc043cf140d2851084512df upstream.
We need to handle E820_RAM and E820_RESERVED_KERNEL at the same time.
Also memblock has page aligned range for ram, so we could avoid mapping
partial pages.

commit 5189c2a7c7769ee9d037d76c1a7b8550ccf3481c upstream.
When 32-bit EFI is used with 64-bit kernel (or vice versa), turn off
efi_enabled once setup is done. Beyond setup, it is normally used to
determine if runtime services are available and we will have none.
This will resolve issues stemming from efivars modprobe panicking on a
32/64-bit setup, as well as some reboot issues on similar setups.

Avoid situation when we are on associate state in mac80211 and
on disassociate state in cfg80211. This can results on crash
during modules unload (like showed on this thread:
http://marc.info/?t=134373976300001&r=1&w=2) and possibly other

commit 844ab6f993b1d32eb40512503d35ff6ad0c57030 upstream.
Current logic finds enough space for direct mapping page tables from 0
to end. Instead, we only need to find enough space to cover mr[0].start
to mr[nr_range].end -- the range that is actually being mapped by
init_memory_mapping()
This is needed after 1bbbbe779aabe1f0768c2bf8f8c0a5583679b54a, to address
the panic reported here:

commit f8295ec22cb0f1ee6849b862addbfa3ea9320755 upstream.
These devices provide QMI and ethernet functionality via a standard CDC
ethernet descriptor. But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface. Thus blacklist the devices in cdc_ether and add their IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.

commit 065a13e2cc665f6547dc7e8a9d6b6565badf940a upstream.
When sending a pairing request or response we should not just blindly
copy the value that the remote device sent. Instead we should at least
make sure to mask out any unknown bits. This is particularly critical
from the upcoming LE Secure Connections feature perspective as
incorrectly indicating support for it (by copying the remote value)
would cause a failure to pair with devices that support it.

commit 4045f72bcf3c293c7c5932ef001742d8bb5ded76 upstream.
This patch fix corruption which can manifest itself by following crash
when switching on rfkill switch with rt2x00 driver:
https://bugzilla.redhat.com/attachment.cgi?id=615362
Pointer key->u.ccmp.tfm of group key get corrupted in:
ieee80211_rx_h_michael_mic_verify():
/* update IV in key information to be able to detect replays */
rx->key->u.tkip.rx[rx->security_idx].iv32 = rx->tkip_iv32;
rx->key->u.tkip.rx[rx->security_idx].iv16 = rx->tkip_iv16;
because rt2x00 always set RX_FLAG_MMIC_STRIPPED, even if key is not TKIP.
We already check type of the key in different path in
ieee80211_rx_h_michael_mic_verify() function, so adding additional
check here is reasonable.

commit 3a40414f826a8f1096d9b94c4a53ef91b25ba28d upstream.
Some changes to fix issues with HT40 APs in Korea
and follow-up changes to allow using HT40 even if
the local regulatory database disallows it caused
issues with iwlwifi (and could cause issues with
other devices); iwlwifi firmware would assert if
you tried to connect to an AP that has an invalid
configuration (e.g. using HT40- on channel 140.)
Fix this, while avoiding the "Korean AP" issue by
disabling HT40 and advertising HT20 to the AP
when connecting.

The reason for this is that the Debug Unit Chip ID Register has changed between
Engineering Sample and definitive revision of the SoC. Changing the check of
cidr to socid will address the problem. We do not integrate this check to the
list just above because we also have to make sure that the extended id is
disregarded.

commit 7840487cd6298f9f931103b558290d8d98d41c49 upstream.
The i2c core driver will turn the platform device ID to busnum
When using platfrom device ID as -1, it means dynamically assigned
the busnum. When writing code, we need to make sure the busnum,
and call i2c_register_board_info(int busnum, ...) to register device
if using -1, we do not know the value of busnum
In order to solve this issue, set the platform device ID as a fix number
Here using 0 to match the busnum used in i2c_regsiter_board_info()

commit 308b3afb97dc342e9c4f958d8b4c459ae0e22bd7 upstream.
Commit a5238e360b71 (spi: s3c64xx: move controller information into driver
data) introduced separate device names for the different subtypes of the
spi controller but forgot to set these in the relevant machines.
To fix this introduce a s3c64xx_spi_setname function and populate all
Samsung arches with the correct names. The function resides in a new
header, as the s3c64xx-spi.h contains driver platform data and should
therefore at some later point move out of the Samsung include dir.
Tested on a s3c2416-based machine.

commit e681b66f2e19fadbe8a7e2a17900978cb6bc921f upstream.
Remove private zombie flag used to signal disconnect and to prevent
control urb from being submitted from interrupt urb completion handler.
The control urb will not be re-submitted as both the control urb and the
interrupt urb is killed on disconnect.

commit 28c3ae9a8cf45f439c9a0779ebd0256e2ae72813 upstream.
The private int_urb is never allocated so the submission from the
control completion handler will always fail. Remove this odd piece of
broken code.

commit 3eb55cc4ed88eee3b5230f66abcdbd2a91639eda upstream.
The driver set the usb-serial port pointers to NULL on errors in attach,
effectively preventing usb-serial core from decrementing the port ref
counters and releasing the port devices and associated data.

commit f525c05babc7938cc1d4236550fd8a659fb05960 upstream.
Fix port-data memory leak by moving port data allocation and
deallocation to port_probe and port_remove.
Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer freed at release as
it is no longer accessible.
Note also that urb-count for multi-port interfaces has not been changed
even though the usb-serial port number is now determined from the port
and interface minor numbers.
Compile-only tested.

commit f7bc5051667b74c3861f79eed98c60d5c3b883f7 upstream.
I found a memory leak in sierra_release() (well sierra_probe() I guess)
that looses 8 bytes each time the driver releases a device.

commit 40d04738491d7ac1aa708ba434ff3480ec9e1b96 upstream.
Fix port-data memory leak by moving port data allocation and
deallocation to port_probe and port_remove.
Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer freed at release as
it is no longer accessible.
Note that this also fixes memory leaks in the error path of attach where
the write urbs were not freed on errors.
Make sure all interface-data deallocation is done in release by moving
the read urb deallocation from disconnect.
Note that the write urb is killed during close so that the call in
disconnect was superfluous.
Compile-only tested.

Note that the fifth port (command port) is never registered as a
