From: Sam Ravnborg Date: Sat, 26 Feb 2011 07:02:11 +0000 (-0800) Subject: sparc32,sun4m: percpu and global register definitions moved to irq.h X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0399bb5b918bd8ffbf065a3db142ff121aaa18e0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git sparc32,sun4m: percpu and global register definitions moved to irq.h entry.S access percpu + global data defined in sun4m_irq.c - so move the types to irq.h. This makes sparse happy and allow us to utilize asm-offsets later. Also updated a few comments in the sun4m_irq.c file. Signed-off-by: Sam Ravnborg Signed-off-by: David S.
