This reverts commit f7345ccc62a4b880cf76458db5f320725f28e400.
swake_up_one_online() has been removed because hrtimers can now assign
a proper online target to hrtimers queued from offline CPUs. Therefore
remove the related hackery.

It's now ok to perform a wake-up from an offline CPU because the
resulting armed scheduler bandwidth hrtimers are now correctly targeted
by hrtimer infrastructure.
Remove the obsolete hackerry.

hrtimers are migrated away from the dying CPU to any online target at
the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers
handling tasks involved in the CPU hotplug forward progress.
However wake ups can still be performed by the outgoing CPU after
CPUHP_AP_HRTIMERS_DYING. Tho
5c0930ccaad5 ("hrtimers: Push pending hrtimers away from outgoing CPU earlier")
was introduced to fix stalls with scheduler bandwidth timers getting
migrated while some kthreads handling CPU hotplug rely on bandwidth.
However this has introduced several other issues which used to be
confined to RC

Migrate the PCI endpoint test to Kselftest framework. All the tests that
were part of the previous pcitest.sh file were migrated.
Below is the exclusive list of tests:
1. BAR Tests (BAR0 to BAR5)
2. Consecutive BAR Tests
3. Legacy IRQ Tests
4. MSI Interrupt Tests (MSI1 to MSI32)
5. MSI-X Interrup
This just moves the existing tests under tools/pci to
tools/testing/selftests/pci_endpoint and adjusts the paths in Makefile
accordingly. Migration to Kselftest framework will be done in subsequent
commits.

IOCTLs are supposed to return 0 for success and negative error codes for
failure. Currently, this driver is returning 0 for failure and 1 for
success, that's not correct. Hence, fix it!

Hi,
This series carries forward the effort to add Kselftest for PCI Endpoint
Subsystem started by Aman Gupta [1] a while ago. I reworked the initial version
based on another patch that fixes the return values of IOCTLs in
pci_endpoint_test driver and did many cleanups. Since the resulting work
