Input: hyper-v - fix wakeup from suspend-to-idle
It makes little sense but still possible to put Hyper-V guests into
suspend-to-idle state. To wake them up two wakeup sources were registered
in the past: hyperv-keyboard and hid-hyperv. However, since
commit eed4d47efe95 ("ACPI / sleep: Ignore spurious SCI wakeups from
suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch
to pm_wakeup_hard_event() API as these devices are actually the only
possible way to wakeup Hyper-V guests.
Fixes: eed4d47efe95 (ACPI / sleep: Ignore spurious SCI wakeups from
suspend-to-idle)

Title:
[Hyper-V] VM console orphan newline input during login
Status in linux-azure package in Ubuntu:
New
Bug description:
In Bionic azure-edge proposed kernel 4.18.0-1008 we're observing an issue
that got carried from upstream.
This is the first version we checked specifically for this issue, we don't
have yet a good/bad proposed comparison set of versions.
linux-next-5.0.0-9673b4a-20012019 does not have this issue <- daily upstream
linux-next
linux-next-4.20.0-6a1d293-27122018 has the issue <- all 4.1x/4.2x series from
upstream have this problem.
This behavior can be seen only on Hyper-V, as it must use the VM console UI:
- boot the above kernels.
- try to login with username and password.
- After you input the username and press Enter in the Hyper-V console,
another Enter (newline) is automatically received by the console, making it
impossible to input the password.
Afterward, the console behaves like a series of newlines are received
and it resets after a while, presenting again the linux user login.
Repro rates:
- 100% on WS2019
- on WS2016 depending on situation it might not be visible 100%.
Problem does not exist for Azure, it's specific to Hyper-V VM console
only.
