The ideapad-laptop handles most special keys on various Lenovo Laptops
including the Yoga line. Unfortunately, the Yoga 3 11/13/14 models have
one important exception, which is the Fn-ESC combination.
On other Lenovo Laptops, this is FnLock, which switches the function keys
between the primary (Mute, Vol down, Vol up, ...) and the secondary (F1,
F2, F3, ...) behavior. On the new machines, FnLock is only available
through BIOS setup (possibly through a yet-to-be-implemented feature
in this driver) but not through Fn-ESC, but instead the ESC key itself
switched between ESC and a "Paper Display" app for Windows.
Unfortunately, that means that you can never have both ESC *and* the
function keys working at the same time without needing to press Fn on
one of them.
As pointed out in the official Lenovo Forum by dozens of users, this
makes the machine rather useless for any serious work [1].
I have now studied the ACPI DSDT one more time and found the event
that is generated for the ESC key. Unlike all other key events on this
machine, it is actually a WMI, while the other ones are read from the
embedded controller.
I am now installing a WMI notifier that uses the event number from the
WMI subsystem as the scancode. The only event number generated here is
'128', and that fits in nicely with the two existing ranges of scancodes
used by the EC: 0-15 for the 16-bit VPCCMD_R_VPC register, 16-17 for
the VPCCMD_R_NOVO register and 64-67 for VPCCMD_R_SPECIAL_BUTTONS.
The only sane way to handle this button (in absence of the Windows Paper
Display driver) seems to be to have it emit KEY_ESC, so that is what
I use as the default. Should any user ever want to overwrite the default,
they can install their own keymap.
To ensure that we can still build the driver without adding a CONFIG_WMI
dependency, all new code is enclosed in #ifdef.

The thinkpad_acpi driver currently emits error messages on unsupported
brightness interfaces, giving the impression that someone will implement
those. However, this error is spit out on nearly every thinkpad in
production since 2 years now. Furthermore, the backlight interfaces on
those devices are supported by the i915 driver just fine.
Downgrade the error message to a normal pr_info() and stop telling people
to report it to IBM.

The function parkbd_attach() references
the function __init parkbd_allocate_serio().
This is often because parkbd_attach lacks a __init
annotation or the annotation of parkbd_allocate_serio is wrong.
Commit 33ca8ab97cbb676d ("Input: parkbd - use parallel port device

Pull final round of SCSI updates from James Bottomley:
"Sorry for the delay in this patch which was mostly caused by getting
the merger of the mpt2/mpt3sas driver, which was seen as an essential
item of maintenance work to do before the drivers diverge too much.
Unfortunately, this caused a compile failure (detected by linux-next),
which then had to be fixed up and incubated.
In addition to the mpt2/3sas rework, there are updates from pm80xx,
lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
an assortment of changes including some year 2038 issues, a fix for a
remove before detach issue in some drivers and a couple of other minor
issues"

According to SPC-4, in a Mode Select, the PS bit in Mode Pages is
reserved and must be set to 0 by the driver. In the sd implementation,
function cache_type_store does a Mode Sense, which might set the PS bit
on the read buffer, followed by a Mode Select, which receives the same
buffer, without explicitly clearing the PS bit. So, in cases where
target supports saving the Mode Page to a non-volatile location, we end
up doing a Mode Select with the PS bit set, which could cause an illegal
request error if the target is checking this.
This was observed on a new firmware change, which was subsequently
reverted, but this changes sd.c to be more compliant with SPC-4.
This patch clears the PS bit in the buffer returned by Mode Select,
right before it is used in the Mode Select command.

There is a static checker warning here because "bytes" is controlled by
the user and we cap the upper bound with min() but allow negatives.
Negative bytes will result in some nasty warning messages but are not
super harmful. Anyway, no one needs negative bytes so let's just check
for it and return NULL.

Replace the use of struct timeval and do_gettimeofday() with
64 bit ktime_get_real_seconds. Prevents 32-bit type overflow
in year 2038 on 32-bit systems.
Driver was using the seconds portion of struct timeval (.tv_secs)
to pass a millseconds timestamp to the firmware. This change maintains
that same behavior using ktime_get_real_seconds.
The structure used to pass the timestamp to firmware is 48 bits and
works fine as long as the top 16 bits are zero and they will be zero
for a long time..ie. thousands of years.
Alternative Change: Add sub second granularity to timestamp
As noted above, the driver only used the seconds portion of timeval,
ignores the microseconds portion, and by multiplying by 1000 effectively
does a <<10 and always writes zero into timestamp[0].
The alternative change would pass all the bits to the firmware:
struct timespec64 ts;
ktime_get_real_ts64(&ts);
timestamp = ts.tv_sec * MSEC_PER_SEC + ts.tv_nsec / NSEC_PER_MSEC;

struct mvumi_hs_page2 stores a "seconds_since1970" field which is of
type u64. It is however, written to, using 'struct timeval' which has
a 32-bit seconds field and whose value will overflow in year 2038.
This patch uses ktime_get_real_seconds() instead since it provides a
64-bit seconds value, which is 2038 safe.

The only user of scsi_prep_async_scan() is scsi_scan_host() and it
handles the situation correctly. Move 'called twice' reporting to debug

The issue is observed on Hyper-V: on any device add/remove event storvsc
driver calls scsi_scan_host() and in case previous scan is still running
we get the message and stack dump on console.

Modified the mpt3sas driver to have a single driver module which
supports both SAS 2.0 & SAS 3.0 HBA devices.
* Added SAS 2.0 HBA device IDs to the mpt3sas_pci_table pci table.
* Created two separate SCSI host templates for SAS2 and SAS3 HBAs so
that, during the driver load time driver can use corresponding host
template(based the pci device ID) while registering a scsi host
adapter instance for that pci device.
* Registered two IOCTL devices, mpt2ctl is for SAS2 HBAs & mpt3ctl for
SAS3 HBAs. Also updated the code to make sure that mpt2ctl device
processes only those ioctl cmds issued for the SAS2 HBAs and mpt3ctl
device processes only those ioctl cmds issued for the SAS3 HBAs.
* Added separate indexing for SAS2 and SAS3 HBAs.
* Replaced compile time check 'MPT2SAS_SCSI' to run time check
'hba_mpi_version_belonged' whereever needed.
* Aliased this merged driver to mpt2sas using MODULE_ALIAS.
* Moved global varaible 'driver_name' to per adapter instance variable.
* Created two raid function template and used corresponding raid
function templates based on the run time check
'hba_mpi_version_belonged'.
* Moved mpt2sas_warpdrive.c file from mpt2sas to mpt3sas folder and
renamed it as mpt3sas_warpdrive.c.
* Also renamed the functions in mpt3sas_warpdrive.c file to follow
current driver function name convention.
* Updated the Makefile to build mpt3sas_warpdrive.o file for these
WarpDrive-specific functions.
* Also in function mpt3sas_setup_direct_io(), used sector_div() API
instead of division operator (which gives compilation errors on 32 bit
machines).
* Removed mpt2sas files, mpt2sas directory & mpt3sas_module.c file.
* Added module parameter 'hbas_to_enumerate' which permits using this
merged driver as a legacy mpt2sas driver or as a legacy mpt3sas
driver.
Here are the available options for this module parameter:
0 - Merged driver which enumerates both SAS 2.0 & SAS 3.0 HBAs
1 - Acts as legacy mpt2sas driver, which enumerates only SAS 2.0 HBAs
2 - Acts as legacy mpt3sas driver, which enumerates only SAS 3.0 HBAs
* Removed mpt2sas entries from SCSI's Kconfig and Makefile files.

The fw_event_work struct is concurrently referenced at shutdown. Add a
refcount to protect it and refactor the code to use it.
Additionally, refactor _scsih_fw_event_cleanup_queue() such that it no
longer iterates over the list without holding the lock since
_firmware_event_work() concurrently deletes items from the list.
This patch is ported from commit 008549f6e8a1 ("mpt2sas: Refcount

for mpt3sas.

sas_device objects can be referenced concurrently throughout the driver.
We need a way to make sure threads can't delete them out from under each
other. This patch adds the refcount and refactors the code to use it.
Additionally, we cannot iterate over the sas_device_list without holding
the lock or we risk corrupting random memory if items are added or
deleted as we iterate. This patch refactors _scsih_probe_sas() to use
the sas_device_list in a safe way.
This patch is ported from the following mpt2sas driver commit
d224fe0d6097 ("mpt2sas: Refcount sas_device objects and fix unsafe list
usage").

A new sysfs shost attribute called "BMR_status" is implemented to report
Backup Rail Monitor status.
This attribute is located in:
/sys/class/scsi_host/host#/BMR_status
When reading this adapter attribute, the driver will output the state of
GPIO[24]. It returns "0" if BMR is healthy and "1" for failure.
If it returns an empty string then it means that there was an error
while obtaining the BMR status. Check dmesg for what error has occurred.
This sysfs shost attribute is mainly for WarpDrive controllers.
This commit is a port of 6c265660c262 ("mpt2sas: Provide sysfs attribute
to report Backup Rail Monitor Status").

Currently there is a logging level option provided for each of our
drivers in the kernel configuration utility. Users can enable this
option to get more verbose information. By default it is enabled.
Only when this option is enabled will the functions which display the
required information get compiled in.
As we are merging the both drivers we can no longer provide this
configuration option. Remove the SCSI_MPTXSAS_LOGGING entry from Kconfig
and unconditionally enable logging (by removing the #ifdef
CONFIG_SCSI_MPT3SAS_LOGGING preprocessor check conditions) so that all
functions which are defined to display more verbose information get
compiled in.

Previously, when this module was unloaded via 'rmmod' with at least one
drive attached, the SCSI error handler thread would become stuck in an
infinite recovery loop and lockup the system, necessitating a reboot.
Once the SAS layer is detached, the driver will fail any subsequent
commands since the target devices are removed. However, removing the
SCSI host generates a SYNCHRONIZE CACHE (10) command, which was failed
and left the error handler no method of recovery.
This patch simply removes the SCSI host first so that no more commands
can come down, prior to cleaning up the SAS layer. Note that the stack
is built up with the SCSI host first, and then the SAS layer. Perhaps
it should be reversed for symmetry, so that commands cannot be sent to
the pm80xx driver prior to attaching the SAS layer?
What was really strange about this bug was that it was introduced at
commit cff549e4860f ("[SCSI]: proper state checking and module refcount
handling in scsi_device_get"). This commit appears to tinker with how
the reference counting is performed for SCSI device objects. My theory
is that prior to this commit, the refcount for a device object was
blindly incremented at some point during the teardown process which
coincidentially made the device stick around during the procedure, which
also coincidentially made any commands sent to the driver not fail
(since the device was technically still "there"). After this commit was
applied, my theory is the refcount for the device object is not being
incremented at a specific point anymore, which makes the device go away,
and thus made the pm80xx driver fail any subsequent commands.

commit cff549e4860f ("scsi: proper state checking and module refcount
handling in scsi_device_get") the reference count of scsi device was
changed, which could lead to when rmmod with at least on drive attached,
SCSI error handle will run into infinite loop, and lockup the system.
Fix it by remove scsi host first, this way scsi core will not send
commands down after detaching SAS transport.
This is a follow up fix for Benjamin's fix for pm80xx.

Some new adapters require a special Configure Cache Parameters command
to enable the adapter write cache, so send this during the adapter
initialization if the adapter requires it.

Add an IOA Inquiry command for Page 0xC4 during IOA initialization to
collect cache capabilities, particularly to check if Sync IOA Write
Cache is supported.
Inquiry will happen right after Cap Inquiry on page 0xD0; and will
execute only if the "Supported Pages" field in Inquiry Page 0x0 shows
support for Page 0xC4. Otherwise, assume Sync IOA Write Cache is
not supported.

According to the IPR specification, Inhibit Underlength Checking bit
must be disabled when issuing commands to vsets. Enabling it in this
case might cause SCSI commands to fail with an Illegal Request, so make
sure we keep this bit cleared when resource is a vset.

Add a holding pattern prior to collecting dump data, to wait for the IOA
indication that the Mailbox register is stable and won't change without
an explicit reset. This ensures we'll be collecting meaningful dump
data, even when dumping right after an adapter reset.
In the event of a timeout, we still force the dump, since a partial dump
still might be useful.
