| Subject: s390/irq: remove HAVE_IRQ_EXIT_ON_IRQ_STACK |
| |
| From: Sven Schnelle <svens@linux.ibm.com> |
| |
| [ Upstream commit 0aa4ff7688632a86bdb133fa106f2ccd514b91a7 ] |
| |
| This is no longer true since we switched to generic entry. The code |
| switches to the IRQ stack before calling do_IRQ, but switches back |
| to the kernel stack before calling irq_exit(). |
| |
| Fixes: 56e62a737028 ("s390: convert to generic entry") |
