powerpc/perf/hv-24x7: Fix return value of hcalls
The H_GET_24X7_CATALOG_PAGE hcall can return a signed error code, so fix this in the code. The H_GET_24X7_DATA hcall can return a signed error code, so fix this in the code. Also, don't truncate it to 32 bit to use as return value for make_24x7_request. In case of error h_24x7_event_commit_txn passes that return value to generic code, so it should be a proper errno. The other caller of make_24x7_request is single_24x7_request, whose callers don't actually care which error code is returned so they are not affected by this change. Finally, h_24x7_get_value doesn't use the error code from single_24x7_request, so there's no need to store it. Reviewed-by:Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Signed-off-by:
