From: Randy Dunlap <[email protected]> <linux/irq.h> does not use nor need several of its #included files, so drop those header files from irq.h.
<linux/irq.h> is currently #included in around 1135 C source files (oops, I didn't count other header files that #include it), making it the 29th most-used header file. Build tested on i386 and x86_64 * (allnoconfig, tiny.config, defconfig, allyesconfig, and allmodconfig) and x64_64 allmodconfig + SMP=disabled.
