Heiko Carstens 7e1e0235b3 s390/mem_detect: fix diag260() program check new psw handling ... [ Upstream commit 86807f348f418a84970eebb8f9912a7eea16b497 ] The __diag260() inline asm temporarily changes the program check new psw to redirect a potential program check on the diag instruction. Restoring of the program check new psw is done in C code behind the inline asm. This can be problematic, especially if the function is inlined, since the compiler can reorder instructions in such a way that a different instruction, which may result in a program check, might be executed before the program check new psw has been restored. To avoid such a scenario move restoring into the inline asm. For consistency reasons move also saving of the original program check new psw into the inline asm.
