This patch creates consistent early interfaces for mapping normal memory and eliminates some sparse warnings.
early_memremap() was created to map normal memory, as opposed to the ioremap interfaces for actual IO mappings, so remove the __iomem annotation from early_memremap(). In addition, early_memunmap() is added to provide an interface analogous to early_iounmap() for normal memory. Fixes the following warnings: arch/x86/kernel/setup.c:353:19: warning: incorrect type in assignment (different address spaces) arch/x86/kernel/setup.c:437:22: warning: incorrect type in assignment (different address spaces) arch/x86/kernel/setup.c:465:22: warning: incorrect type in assignment (different address spaces) arch/x86/kernel/setup.c:488:22: warning: incorrect type in assignment (different address spaces) arch/x86/kernel/e820.c:667:15: warning: incorrect type in assignment (different address spaces) Signed-off-by: Linn Crosetto <l...@hp.com> --- arch/x86/include/asm/io.h | 4 ++-- arch/x86/mm/ioremap.c | 9 +++++++-- 2 files changed, 9 insertions(+), 4 deletions(-) diff --git a/arch/x86/include/asm/io.h b/arch/x86/include/asm/io.h index 34f69cb..ae1ef3e 100644 --- a/arch/x86/include/asm/io.h +++ b/arch/x86/include/asm/io.h @@ -325,8 +325,8 @@ extern void early_ioremap_init(void); extern void early_ioremap_reset(void); extern void __iomem *early_ioremap(resource_size_t phys_addr, unsigned long size); -extern void __iomem *early_memremap(resource_size_t phys_addr, - unsigned long size); +extern void *early_memremap(resource_size_t phys_addr, unsigned long size); +extern void early_memunmap(void *addr, unsigned long size); extern void early_iounmap(void __iomem *addr, unsigned long size); extern void fixup_early_ioremap(void); extern bool is_early_ioremap_ptep(pte_t *ptep); diff --git a/arch/x86/mm/ioremap.c b/arch/x86/mm/ioremap.c index 799580c..a144929 100644 --- a/arch/x86/mm/ioremap.c +++ b/arch/x86/mm/ioremap.c @@ -562,10 +562,15 @@ early_ioremap(resource_size_t phys_addr, unsigned long size) } /* Remap memory */ -void __init __iomem * +void __init * early_memremap(resource_size_t phys_addr, unsigned long size) { - return __early_ioremap(phys_addr, size, PAGE_KERNEL); + return (__force void *)__early_ioremap(phys_addr, size, PAGE_KERNEL); +} + +void __init early_memunmap(void *addr, unsigned long size) +{ + early_iounmap((void __iomem *)addr, size); } void __init early_iounmap(void __iomem *addr, unsigned long size) -- 1.7.11.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
