commit 3bda2b55b4 ("Merge android-4.4.96 (aed4c54) into msm-4.4")
replaced HMP scheduler check_for_migration() implementation with
EAS scheduler implementation. This breaks HMP scheduler upmgiration
functionality. Fix this by restoring the previous implementation.

gsi_eth_fs_function is array of pointers to set of RNDIS interface
related descriptors. gsi_eth_fs_function's first descriptor is
pointing itself instead of required RNDIS IAD descriptor. This
results into out-of-bound read access while copying these set of
descriptors with usb_copy_descriptors() API. Fix this issue by
using required RNDIS IAD descriptor here.

Default IPA header is added or deleted from the driver
directly and not by user space application. This change
prevents adding/deleting it from user application which
may cause inconsistencies in the driver. Also the change
fixes the header reset function to skip on the correct
default header.

enter_lazy_tlb is called when a kernel thread rides on the back of
another mm, due to a context switch or an explicit call to unuse_mm
where a call to switch_mm is elided.
In these cases, it's important to keep the saved ttbr value up to date
with the active mm, otherwise we can end up with a stale value which
points to a potentially freed page table.
This patch implements enter_lazy_tlb for arm64, so that the saved ttbr0
is kept up-to-date with the active mm for kernel threads.

update_saved_ttbr0 mandates that mm->pgd is not swapper, since swapper
contains kernel mappings and should never be installed into ttbr0. However,
this means that callers must avoid passing the init_mm to update_saved_ttbr0
which in turn can cause the saved ttbr0 value to be out-of-date in the context
of the idle thread. For example, EFI runtime services may leave the saved ttbr0
pointing at the EFI page table, and kernel threads may end up with stale
references to freed page tables.
This patch changes update_saved_ttbr0 so that the init_mm points the saved
ttbr0 value to the empty zero page, which always exists and never contains
valid translations. EFI and switch can then call into update_saved_ttbr0
unconditionally.

It is observed that the hard ID IRQ is enabled when the
threaded IRQ handler for the same is still running. In that
case, there are two issues. The ID LOW IRQ can come
consecutively which will increase the disable count of
vbus_irq. Then ID HIGH IRQ will not enable the vbus_irq and
peripheral mode detection will not work anymore. The second
issue is that ID HIGH IRQ is fired just before ID LOW IRQ.
This will mark usb->id_state from HIGH to LOW even while
threaded IRQ is running which will lead to host not getting
stopped and peripheral mode not working.
Fix both issues by maintaning a local copy of ID IRQ in
threaded IRQ handler and comparing it with previous ID state.
If same, then bail out.

When the battery is in cold temperature for a certain amount of
time and device is charged with Qnovo enabled charging, ESR pulse
will fire less frequently. This along with ESR pulses not getting
qualified can cause the ESR to be less accurate. To improve ESR
accuracy, add change to apply relaxed filter coefficients once
the battery temperature starts ramping up after hitting a lower
threshold of say 6 C after charging begins.

If modem crashed during wlan driver unloading, icnss driver
will call driver uevent callback to send FW down uevent when
it receives BEFORE_SHUTDOWN notification. If wlan driver is
de-initialized just before the callback is called, kernel will
panic as driver's context is freed. This can be avoid by not
sending uevent when wlan host driver is unloading. Instead,
icnss driver will provide an API to host driver to check if
WLAN FW is down or not.
