This patchset allows for setup_rfi_flush() to be called again
after PowerVM LPM (live partition mobility) aka LPAR migration,
in order to possibly switch to a different flush method.
The patches are mostly from Michael Ellerman, I have rebased to
powerpc/linux.git merge branch as of commit d8443ef (March 14).
Testcase and results sent as the last email in the series.
v3: add patch 4 to tell flush types are 'available' and not 'Using'.
remove plumbing patch.
v2: add plumbing patch between platforms and setup code to
force init fallback flush.
Mauricio Faria de Oliveira (1):
rfi-flush: Differentiate enabled and patched flush types
Michael Ellerman (4):
rfi-flush: Move the logic to avoid a redo into the debugfs code
rfi-flush: Make it possible to call setup_rfi_flush() again
rfi-flush: Always enable fallback flush on pseries
rfi-flush: Call setup_rfi_flush() after LPM migration
