commit 5c45d04c5081c1830d674f4d22d4400ea2083afe upstream.
This is a UPB (Universal Powerline Bus) PIM (Powerline Interface Module)
which allows for controlling multiple UPB compatible devices from Linux
using the standard serial interface.
Based on vendor application source code there are two different models
of USB based PIM devices in addition to a number of RS232 based PIM's.
The vendor UPB application source contains the following USB ID's:
#define USB_PCS_VENDOR_ID 0x04b4
#define USB_PCS_PIM_PRODUCT_ID 0x5500
#define USB_SAI_VENDOR_ID 0x17dd
#define USB_SAI_PIM_PRODUCT_ID 0x5500
The first set of ID's correspond to the PIM variant sold by Powerline
Control Systems while the second corresponds to the Simply Automated
Incorporated PIM. As the product ID for both of these match the default
cypress HID->COM RS232 product ID it assumed that they both use an
internal variant of this HID->COM RS232 converter hardware. However
as the vendor ID for the Simply Automated variant is different we need
to also add it to the cypress_M8 driver so that it is properly
detected.

commit 9b7e5208a941e2e491a83eb5fa83d889e888fa2f upstream.
USB MIDI driver has an error recovery mechanism to resubmit the URB in
the delayed timer handler, and this may race with the standard start /
stop operations. Although both start and stop operations themselves
don't race with each other due to the umidi->mutex protection, but
this isn't applied to the timer handler.
For fixing this potential race, the following changes are applied:
- Since the timer handler can't use the mutex, we apply the
umidi->disc_lock protection at each input stream URB submission;
this also needs to change the GFP flag to GFP_ATOMIC
- Add a check of the URB refcount and skip if already submitted
- Move the timer cancel call at disconnection to the beginning of the
procedure; this assures the in-flight timer handler is gone properly
before killing all pending URBs

commit c27075772d1f1c8aaf276db9943b35adda8a8b65 upstream.
In a previous fix, I changed the condition on which the timeout of an
IRQ is reached from:
if (!ret)
into:
if (ret && !pending)
While having a non-zero return code is usual in the Linux kernel, here
ret comes from a wait_for_completion_timeout() which returns 0 when
the waiting period is too long.
Hence, the revised condition should be:
if (!ret && !pending)
The faulty patch did not produce any error because of the !pending
condition so this change is finally purely cosmetic and does not
change the actual driver behavior.

commit f5ac95f9ca2f439179a5baf48e1c0f22f83d936e upstream.
TCSes have previously programmed data when rpmh_flush() is called.
This can cause old data to trigger along with newly flushed.
Fix this by cleaning SLEEP and WAKE TCSes before new data is flushed.
With this there is no need to invoke rpmh_rsc_invalidate() call from
rpmh_invalidate().
Simplify rpmh_invalidate() by moving invalidate_batch() inside.

commit bb7000677a1b287206c8d4327c62442fa3050a8f upstream.
Currently rpmh ctrlr dirty flag is set for all cases regardless of data
is really changed or not. Add changes to update dirty flag when data is
changed to newer values. Update dirty flag everytime when data in batch
cache is updated since rpmh_flush() may get invoked from any CPU instead
of only last CPU going to low power mode.
Also move dirty flag updates to happen from within cache_lock and remove
unnecessary INIT_LIST_HEAD() call and a default case from switch.

commit 0e0bf1ea1147fcf74eab19c2d3c853cc3740a72f upstream.
As the code comments in perf_stat_process_counter() say, we calculate
counter's data every interval, and the display code shows ps->res_stats
avg value. We need to zero the stats for interval mode.
But the current code only zeros the res_stats[0], it doesn't zero the
res_stats[1] and res_stats[2], which are for ena and run of counter.
This patch zeros the whole res_stats[] for interval mode.

commit c3aaf086701d05a82c8156ee8620af41e5a7d6fe upstream.
26ad34d510 ("PCI / ACPI: Whitelist D3 for more PCIe hotplug ports") added
the struct pci_platform_pm_ops.bridge_d3() function pointer and
platform_pci_bridge_d3() to use it.
The .bridge_d3() op is implemented by acpi_pci_platform_pm, but not by
mid_pci_platform_pm. We don't expect platform_pci_bridge_d3() to be called
on Intel MID platforms, but nothing in the code itself would prevent that.
Check the .bridge_d3() pointer for NULL before calling it.

Currently it is possible to specify a state machine table with 0 length,
this is not valid as optional tables are specified by not defining
the table as present. Further this allows by-passing the base tables
range check against the next/check tables.

commit 5714ee50bb4375bd586858ad800b1d9772847452 upstream.
This fixes a regression encountered while running the
gdb.base/corefile.exp test in GDB's test suite.
In my testing, the typo prevented the sw_reserved field of struct
fxregs_state from being output to the kernel XSAVES area. Thus the
correct mask corresponding to XCR0 was not present in the core file for
GDB to interrogate, resulting in the following behavior:
[kev@f32-1 gdb]$ ./gdb -q testsuite/outputs/gdb.base/corefile/corefile testsuite/outputs/gdb.base/corefile/corefile.core
Reading symbols from testsuite/outputs/gdb.base/corefile/corefile...
[New LWP 232880]
warning: Unexpected size of section `.reg-xstate/232880' in core file.
With the typo fixed, the test works again as expected.

[ Upstream commit 299632e54b2e692d2830af84be51172480dc1e26 ]
If a regmap has "fast_io" set then its lock function uses a spinlock.
That doesn't work so well with the functions:
* regmap_cache_only_write_file()
* regmap_cache_bypass_write_file()
Both of the above functions have the pattern:
1. Lock the regmap.
2. Call:
debugfs_write_file_bool()
copy_from_user()
__might_fault()
__might_sleep()
Let's reorder things a bit so that we do all of our sleepable
functions before we grab the lock.

actually, Tony has fixed this issue on am335x with the patch [3]
Since am437x has the same clock structure with am335x
[1][2], so reuse the code from Tony Lindgren's patch [3] to fix it.
