+Subject: header: fix compile error on PowerPC (PPC_85xx)
+
+Including linux/interrupt.h in linux/hrtimer.h causes this error message
+on PowerPC builds on x86, ARM and MIPS it works:
+
+ CC [M] /backports-4.14-rc2-1/compat/main.o
+In file included from /backports-4.14-rc2-1/backport-include/linux/printk.h:5:0,

+ from /backports-4.14-rc2-1/compat/main.c:1:
+./include/linux/ratelimit.h: In function 'ratelimit_state_exit':
+./include/linux/ratelimit.h:62:11: error: dereferencing pointer to incomplete type 'struct task_struct'
+ current->comm, rs->missed);
+ ^
+./include/linux/printk.h:279:37: note: in definition of macro 'pr_warning'
+ printk(KERN_WARNING pr_fmt(fmt), ##__VA_ARGS__)
+ ^
+./include/linux/ratelimit.h:61:3: note: in expansion of macro 'pr_warn'
+ pr_warn("%s: %d output lines suppressed due to ratelimiting\n",
+ ^
+
+The backport of the hrtimer_start() functions needs the
+linux/interrupt.h because some parts are defined there. Fix this by
+moving the hrtimer_start() backport to the linux/interrupt.h backport
+header file.
