Johannes Berg <johannes@sipsolutions.net> says:
"Two more fixes for mac80211 - one of them addresses a long-standing
issue that we only found when using vendor events more frequently;
the other addresses some bad information being reported in userspace
that people were starting to actually look at."

In the Generic PHY Framework a NULL phy is considered to be a valid phy
thus the "if (hsotg->phy)" check does not give us the information whether
the Generic PHY Framework is used.
In addition to the above this patch also removes phy_init from probe and
phy_exit from remove. This is not necessary when init/exit is done in the
s3c_hsotg_phy_enable/disable functions.

When the driver is removed s3c_hsotg_phy_disable is called three times
instead of once. This results in decreasing of the phy reference counter
below zero and thus consecutive inserts of the module fails.
This patch removes calls to s3c_hsotg_phy_disable from s3c_hsotg_remove
and s3c_hsotg_udc_stop.
s3c_hsotg_udc_stop is called from udc-core.c only after
usb_gadget_disconnect, which in turn calls s3c_hsotg_pullup, which
already calls s3c_hsotg_phy_disable.
s3c_hsotg_remove must be called only after udc_stop, so there is no
point in disabling phy once again there.

When a queue is registered, the block layer turns off the bypass
setting (because bypass is enabled when the queue is created). This
doesn't work well for queues that are unregistered and then registered
again; we get a WARNING because of the unbalanced calls to
blk_queue_bypass_end().
This patch fixes the problem by making blk_register_queue() call
blk_queue_bypass_end() only the first time the queue is registered.

Commit 21278aeafbfa ("ARM: use menuconfig for sub-arch menus") improved
the sub-arch menus, but accidentally caused new warnings for omap1.
This was because the commit added a menu entry around config ARCH_OMAP
bool entry where the menu had depends on ARCH_MULTI_V6 || ARCH_MULTI_V7.
As ARCH_OMAP is shared between omap1 and omap2plus, let's fix the
issue by defining ARCH_OMAP in the shared plat-omap/Kconfig.

charged"
This reverts commit 232de5143790 ("ACPI / battery: fix wrong value of
capacity_now reported when fully charged")
There is nothing wrong or unexpected about 'capacity_now' increasing above
the last 'full_charge_capacity' value. Different charging cycles will cause
'full_charge_capacity' to vary, both up and down. Good battery firmwares
will update 'full_charge_capacity' when the current charging cycle is
complete, increasing it if necessary. It might even go above
'design_capacity' on a fresh and healthy battery.
Capping 'capacity_now' to 'full_charge_capacity' is plain wrong, and
printing a warning if this doesn't happen to match the 'design_capacity'
is both annoying and terribly wrong.
This results in bogus warnings on perfectly working systems/firmwares:
[Firmware Bug]: battery: reported current charge level (39800) is higher than reported maximum charge level (39800).
and wrong values being reported for 'capacity_now' and
'full_charge_capacity' after the warning has been triggered.

This reverts commit d719870b41e0 ("ACPI / battery: Fix warning message in
acpi_battery_get_state()")
Capping 'capacity_now' to 'full_charge_capacity' is plain wrong. If this
is necessary to work around some buggy firmware, then the workaround needs
protection against being applied to working firmwares.
Good battery firmwares will allow 'capacity_now' to increase above
'full_charge_capacity', and will update the latter when the battery
is fully charged. By capping 'capacity_now' we lose accurate capacity
reporting until charging is complete whenever 'full_charge_capacity'
needs to be increased.

When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which
also depends on the modules number in Makefile. The related information
in "scripts/Makefile.lib" line 94:
# $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will
# end up in (or would, if it gets compiled in)
# Note: Files that end up in two or more modules are compiled without the
# KBUILD_MODNAME definition. The reason is that any made-up name would
# differ in different configs.
For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in
one line, so cause compiling issue. And 'uaccess.h' is a common shared
header (not specially for drivers), so use pr_devel() instead of is OK.
The related error with allmodconfig:

ABIv2 kernels are failing to backtrace through the kernel. An example:
39.30% readseek2_proce [kernel.kallsyms] [k] find_get_entry
|
--- find_get_entry
__GI___libc_read
The problem is in valid_next_sp() where we check that the new stack
pointer is at least STACK_FRAME_OVERHEAD below the previous one.
ABIv1 has a minimum stack frame size of 112 bytes consisting of 48 bytes
and 64 bytes of parameter save area. ABIv2 changes that to 32 bytes
with no paramter save area.
STACK_FRAME_OVERHEAD is in theory the minimum stack frame size,
but we over 240 uses of it, some of which assume that it includes
space for the parameter area.
We need to work through all our stack defines and rationalise them
but let's fix perf now by creating STACK_FRAME_MIN_SIZE and using
in valid_next_sp(). This fixes the issue:
30.64% readseek2_proce [kernel.kallsyms] [k] find_get_entry
|
--- find_get_entry
pagecache_get_page
generic_file_read_iter
new_sync_read

Commit 86c8b27a01cf:
"arm64: ignore DT memreserve entries when booting in UEFI mode
prevents early_init_fdt_scan_reserved_mem() from being called for
arm64 kernels booting via UEFI. This was done because the kernel
will use the UEFI memory map to determine reserved memory regions.
That approach has problems in that early_init_fdt_scan_reserved_mem()
also reserves the FDT itself and any node-specific reserved memory.
By chance of some kernel configs, the FDT may be overwritten before
it can be unflattened and the kernel will fail to boot. More subtle
problems will result if the FDT has node specific reserved memory
which is not really reserved.
This patch has the UEFI stub remove the memory reserve map entries
from the FDT as it does with the memory nodes. This allows
early_init_fdt_scan_reserved_mem() to be called unconditionally
so that the other needed reservations are made.

We saw a kernel soft lockup in perf_remove_from_context(),
it looks like the `perf` process, when exiting, could not go
out of the retry loop. Meanwhile, the target process was forking
a child. So either the target process should execute the smp
function call to deactive the event (if it was running) or it should
do a context switch which deactives the event.
It seems we optimize out a context switch in perf_event_context_sched_out(),
and what's more important, we still test an obsolete task pointer when
retrying, so no one actually would deactive that event in this situation.
Fix it directly by reloading the task pointer in perf_remove_from_context().
This should cure the above soft lockup.

It looks wrong that we add "/proc/net/nfsfs" in nfs_fs_proc_net_init()
while remove "/proc/fs/nfsfs" in nfs_fs_proc_net_exit().

The tx_empty() callback currently checks the TXEMPTY bit in the interrupt
status register to decided whether the FIFO should be reported as empty or
not. The bit in this register gets set when the FIFO state transitions from
non-empty to empty but is cleared again in the interrupt handler. This means
it is not suitable to be used to decided whether the FIFO is currently empty
or not. Instead use the TXEMPTY bit from the status register which will be
set as long as the FIFO is empty.

Adding support for the DRV2667 haptic driver. This device has the ability
to store vibration patterns in RAM and execute them once the GO bit is set.
The initial driver sets a basic waveform in the first waveform sequence and
will play the waveform when the GO bit is set and will continously play the
waveform until the GO bit is unset.
Data sheet is here: http://www.ti.com/product/drv2667

Make sure the uwb_dev->bce entry is set before calling uwb_dev_add in
uwbd_dev_onair so that usermode will only see the device after it is
properly initialized. This fixes a kernel panic that can occur if
usermode tries to access the IEs sysfs attribute of a UWB device before
the driver has had a chance to set the beacon cache entry.

====================
net: systemport and bcmgenet OOM fixes
These two patches fix similar Out of Memory code paths in the SYSTEMPORT and
GENET drivers. Under high memory pressure, we could produce an OOPS by
passing a NULL pointer to dma_unmap_single().

There is a potential case where we might be failing to refill a
control block, leaving it with both a NULL skb pointer *and* a NULL
dma_unmap_addr.
The way we process incoming packets, by first calling
dma_unmap_single(), and then only checking for a potential NULL skb can
lead to situations where do pass a NULL dma_unmap_addr() to
dma_unmap_single(), resulting in an oops.
Fix this my moving the NULL skb check earlier, since no backing skb
also means no corresponding DMA mapping for this packet.

It is useful for userspace to know that there not dealing with a regular
mouse but rather with a pointing stick (e.g. a trackpoint) so that
userspace can e.g. automatically enable middle button scrollwheel
emulation.
It is impossible to tell the difference from the evdev info without
resorting to putting a list of device / driver names in userspace, this is
undesirable.
Add a property which allows userspace to see if a device is a pointing
stick, and set it on all the pointing stick drivers.
