From 6209ed9d8443b63c36d340908530fa470c4d4fff Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 24 Jul 2008 12:49:26 -0700 Subject: x86-64: make BUILD_IRQ() also reset section back Commit 9d25d4db81833029d30b7b03cc1000cbbe09e192 ("x86: BUILD_IRQ say .text to avoid .data.percpu") added a ".text" specifier to make sure that BUILD_IRQ() builds the irq trampoline in the text segment rather than in some random left-over segment that the compiler happened to leave the asm in. However, we should also make sure that we switch back by adding a ".previous" at the end, so that there are no subtle issues with subsequent compiler-generated code.
