This fixes the following error when building for powerpc platforms with CONFIG_PCI=n. drivers/built-in.o: undefined reference to `pci_io_base' Signed-off-by: Geoff Levand Acked-by: Linas Vepstas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- diff --git a/drivers/char/mem.c b/drivers/char/mem.c index 4ac70ec697..6511012cbd 100644 --- a/drivers/char/mem.c +++ b/drivers/char/mem.c @@ -551,7 +551,7 @@ static ssize_t write_kmem(struct file * file, const char __user * buf, return virtr + wrote; } -#if defined(CONFIG_ISA) || !defined(__mc68000__) +#if (defined(CONFIG_ISA) || defined(CONFIG_PCI)) && !defined(__mc68000__) static ssize_t read_port(struct file * file, char __user * buf, size_t count, loff_t *ppos) { @@ -830,7 +830,7 @@ static const struct file_operations null_fops = { .splice_write = splice_write_null, }; -#if defined(CONFIG_ISA) || !defined(__mc68000__) +#if (defined(CONFIG_ISA) || defined(CONFIG_PCI)) && !defined(__mc68000__) static const struct file_operations port_fops = { .llseek = memory_lseek, .read = read_port, @@ -908,7 +908,7 @@ static int memory_open(struct inode * inode, struct file * filp) case 3: filp->f_op = &null_fops; break; -#if defined(CONFIG_ISA) || !defined(__mc68000__) +#if (defined(CONFIG_ISA) || defined(CONFIG_PCI)) && !defined(__mc68000__) case 4: filp->f_op = &port_fops; break; @@ -955,7 +955,7 @@ static const struct { {1, "mem", S_IRUSR | S_IWUSR | S_IRGRP, &mem_fops}, {2, "kmem", S_IRUSR | S_IWUSR | S_IRGRP, &kmem_fops}, {3, "null", S_IRUGO | S_IWUGO, &null_fops}, -#if defined(CONFIG_ISA) || !defined(__mc68000__) +#if (defined(CONFIG_ISA) || defined(CONFIG_PCI)) && !defined(__mc68000__) {4, "port", S_IRUSR | S_IWUSR | S_IRGRP, &port_fops}, #endif {5, "zero", S_IRUGO | S_IWUGO, &zero_fops},
