From mboxrd@z Thu Jan 1 00:00:00 1970 From: Javier Martinez Canillas Date: Sun, 12 Sep 2010 13:48:25 +0000 Subject: [PATCH] ACPI: apei: Cast u64 to unsigned long, fix compile warning Message-Id: <1284299305.7239.4.camel@lenovo> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit To: Len Brown , Huang Ying , Andrew Morton , Andi Kleen , Thomas Gleixner , linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org, kernel-janitors@vger.kernel.org In today linux-net I got a compile warning in acpi/apei drivers/acpi/apei/erst.c: In function ‘erst_exec_move_data’: drivers/acpi/apei/erst.c:273: warning: cast to pointer from integer of different size drivers/acpi/apei/erst.c:274: warning: cast to pointer from integer of different size The problem is that apei_exec_context->dst_base type is u64. But in 32 bits architecture void * is 32 bits long. Casting it to unsigned long solves the issue Signed-off-by: Javier Martinez Canillas --- drivers/acpi/apei/erst.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/acpi/apei/erst.c b/drivers/acpi/apei/erst.c index a4904f1..37d7a05 100644 --- a/drivers/acpi/apei/erst.c +++ b/drivers/acpi/apei/erst.c @@ -270,8 +270,8 @@ static int erst_exec_move_data(struct apei_exec_context *ctx, rc = __apei_exec_read_register(entry, &offset); if (rc) return rc; - memmove((void *)ctx->dst_base + offset, - (void *)ctx->src_base + offset, + memmove((void *)(unsigned long)ctx->dst_base + offset, + (void *)(unsigned long)ctx->src_base + offset, ctx->var2); return 0; -- 1.7.0.4
