X-Git-Tag: next-20131017~19^2~174 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8addac75a1ab0d8bd5fd25dbbc58e02ddfb089c9;p=karo-tx-linux.git zsmalloc: Fix "map_vm_area" undefined reference errors. This patch adds a MMU dependency to configure the ZSMALLOC in drivers/staging/zsmalloc/Kconfig. Without this patch, build system can lead to build failure. This was observed during randconfig testing, in which ZSMALLOC was enabled w/o MMU being enabled. Following was the error: LD vmlinux drivers/built-in.o: In function `__zs_map_object': drivers/staging/zsmalloc/zsmalloc-main.c:650: undefined reference to `map_vm_area' make: *** [vmlinux] Error 1 Signed-off-by: Manjunath Goudar Cc: Nitin Gupta Cc: Seth Jennings Cc: Greg Kroah-Hartman Cc: Minchan Kim Cc: Joerg Roedel Cc: devel@driverdev.osuosl.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/staging/zsmalloc/Kconfig b/drivers/staging/zsmalloc/Kconfig index 7fab032298f3..0ae13cd0908e 100644 --- a/drivers/staging/zsmalloc/Kconfig +++ b/drivers/staging/zsmalloc/Kconfig @@ -1,5 +1,6 @@ config ZSMALLOC bool "Memory allocator for compressed pages" + depends on MMU default n help zsmalloc is a slab-based memory allocator designed to store
