Arnd Bergmann 760baae7ab vme: bridges: reduce stack usage ... [ Upstream commit 7483e7a939 ] With CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3, the stack usage in vme_fake grows above the warning limit: drivers/vme/bridges/vme_fake.c: In function 'fake_master_read': drivers/vme/bridges/vme_fake.c:610:1: error: the frame size of 1160 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] drivers/vme/bridges/vme_fake.c: In function 'fake_master_write': drivers/vme/bridges/vme_fake.c:797:1: error: the frame size of 1160 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] The problem is that in some configurations, each call to fake_vmereadX() puts another variable on the stack. Reduce the amount of inlining to get back to the previous state, with no function using more than 200 bytes each.
