From cae022f91174fabce164cf3d061edaaad0eacb1f Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Wed, 13 Oct 2021 22:06:06 -0700 Subject: [PATCH] net: tulip: winbond-840: fix build for UML MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit a3d708925fcca1a2f7219bc9ce93e6341f85c1e0 ] On i386, when builtin (not a loadable module), the winbond-840 driver inspects boot_cpu_data to see what CPU family it is running on, and then acts on that data. The "family" struct member (x86) does not exist when running on UML, so prevent that test and do the default action. Prevents this build error on UML + i386: ../drivers/net/ethernet/dec/tulip/winbond-840.c: In function ‘init_registers’: ../drivers/net/ethernet/dec/tulip/winbond-840.c:882:19: error: ‘struct cpuinfo_um’ has no member named ‘x86’ if (boot_cpu_data.x86 <= 4) { Fixes: 68f5d3f3b654 ("um: add PCI over virtio emulation driver") Signed-off-by: Randy Dunlap Cc: linux-um@lists.infradead.org Cc: Jeff Dike Cc: Richard Weinberger Cc: Anton Ivanov Link: https://lore.kernel.org/r/20211014050606.7288-1-rdunlap@infradead.org Signed-off-by: Jakub Kicinski Signed-off-by: Sasha Levin --- drivers/net/ethernet/dec/tulip/winbond-840.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/ethernet/dec/tulip/winbond-840.c b/drivers/net/ethernet/dec/tulip/winbond-840.c index 85b99099c6b94..5babcf05bc2f1 100644 --- a/drivers/net/ethernet/dec/tulip/winbond-840.c +++ b/drivers/net/ethernet/dec/tulip/winbond-840.c @@ -877,7 +877,7 @@ static void init_registers(struct net_device *dev) 8000 16 longwords 0200 2 longwords 2000 32 longwords C000 32 longwords 0400 4 longwords */ -#if defined (__i386__) && !defined(MODULE) +#if defined (__i386__) && !defined(MODULE) && !defined(CONFIG_UML) /* When not a module we can work around broken '486 PCI boards. */ if (boot_cpu_data.x86 <= 4) { i |= 0x4800; -- 2.30.2
