From 4a8a0788a36c923a0229beae5e88d9849e359db5 Mon Sep 17 00:00:00 2001 From: Rolf Eike Beer Date: Thu, 10 May 2012 23:08:17 +0200 Subject: parisc: move definition of PAGE0 to asm/page.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This was defined in asm/pdc.h which needs to include asm/page.h for __PAGE_OFFSET. This leads to an include loop so that page.h eventually will include pdc.h again. While this is no problem because of header guards, it is a problem because some symbols may be undefined. Such an error is this: In file included from include/linux/bitops.h:35:0, from include/asm-generic/getorder.h:7, from arch/parisc/include/asm/page.h:162, from arch/parisc/include/asm/pdc.h:346, from arch/parisc/include/asm/processor.h:16, from arch/parisc/include/asm/spinlock.h:6, from arch/parisc/include/asm/atomic.h:20, from include/linux/atomic.h:4, from include/linux/sysfs.h:20, from include/linux/kobject.h:21, from include/linux/device.h:17, from include/linux/eisa.h:5, from arch/parisc/kernel/pci.c:11: arch/parisc/include/asm/bitops.h: In function ‘set_bit’: arch/parisc/include/asm/bitops.h:82:2: error: implicit declaration of function ‘_atomic_spin_lock_irqsave’ [-Werror=implicit-function-declaration] arch/parisc/include/asm/bitops.h:84:2: error: implicit declaration of function ‘_atomic_spin_unlock_irqrestore’ [-Werror=implicit-function-declaration] Signed-off-by: Rolf Eike Beer Signed-off-by: Linus Torvalds --- arch/parisc/kernel/pdc_cons.c | 1 + arch/parisc/kernel/time.c | 1 + 2 files changed, 2 insertions(+) (limited to 'arch/parisc/kernel') diff --git a/arch/parisc/kernel/pdc_cons.c b/arch/parisc/kernel/pdc_cons.c index 0b3393381a8..47341aa208f 100644 --- a/arch/parisc/kernel/pdc_cons.c +++ b/arch/parisc/kernel/pdc_cons.c @@ -50,6 +50,7 @@ #include #include #include +#include /* for PAGE0 */ #include /* for iodc_call() proto and friends */ static DEFINE_SPINLOCK(pdc_console_lock); diff --git a/arch/parisc/kernel/time.c b/arch/parisc/kernel/time.c index 7c0774397b8..70e105d6242 100644 --- a/arch/parisc/kernel/time.c +++ b/arch/parisc/kernel/time.c @@ -29,6 +29,7 @@ #include #include #include +#include #include #include #include -- cgit v1.2.3-70-g09d2
