A quirk of # this interface is that the bind address will only be returned by the # first bind h-call and the subsequent calls will return # 0xFFFF_FFFF_FFFF_FFFF for the bind address. # # We currently do not save the address returned by the first h-call. As a # result we will use the junk address as the base of the bound region if # the hypervisor decides to split the bind across multiple h-calls. This # bug was found when testing with very large SCM volumes where the bind # process would take more time than they hypervisor's internal h-call time # limit would allow. This patch fixes the issue by saving the bind address # from the first call. # # Cc: stable@vger.kernel.org # Fixes: b5beae5e224f ("powerpc/pseries: Add driver for PAPR SCM regions") # Signed-off-by:
