parisc: move definition of PAGE0 to asm/page.h
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 <eike-kernel@sf-tec.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
