From dc60dc133ac0e82dfcd41fc18af74a58aff7ba35 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Thu, 20 Jun 2019 11:15:28 +0200 Subject: [PATCH] brcm2708: Adapt patches to kernel update In kernel 4.4.182 get_user_pages() does not get the write and force parameter any more, but one flags parameter with WRITE and FORCE attributes. This adapts the patches to use the changed API and fixes the compile problems with the brcm2708 target. This fixes the following compile problem: drivers/misc/vc04_services/interface/vchiq_arm/vchiq_arm.c: In function 'dump_phys_mem': drivers/misc/vc04_services/interface/vchiq_arm/vchiq_arm.c:1501:3: warning: passing argument 7 of 'get_user_pages' from incompatible pointer type [-Wincompatible-pointer-types] pages, /* pages (array of page pointers) */ ^ In file included from drivers/misc/vc04_services/interface/vchiq_arm/vchiq_arm.c:42:0: include/linux/mm.h:1200:6: note: expected 'struct vm_area_struct **' but argument is of type 'struct page **' long get_user_pages(struct task_struct *tsk, struct mm_struct *mm, ^ drivers/misc/vc04_services/interface/vchiq_arm/vchiq_arm.c:1495:7: error: too many arguments to function 'get_user_pages' rc = get_user_pages(current, /* task */ ^ In file included from drivers/misc/vc04_services/interface/vchiq_arm/vchiq_arm.c:42:0: include/linux/mm.h:1200:6: note: declared here long get_user_pages(struct task_struct *tsk, struct mm_struct *mm, ^ scripts/Makefile.build:277: recipe for target 'drivers/misc/vc04_services/interface/vchiq_arm/vchiq_arm.o' failed Fixes: 6c5c3a2edccf ("kernel: Update to version 4.4.182") Signed-off-by: Hauke Mehrtens --- .../patches-4.4/0036-bcm2708-vchiq-driver.patch | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/target/linux/brcm2708/patches-4.4/0036-bcm2708-vchiq-driver.patch b/target/linux/brcm2708/patches-4.4/0036-bcm2708-vchiq-driver.patch index 7247fa6951..f53b065ec7 100644 --- a/target/linux/brcm2708/patches-4.4/0036-bcm2708-vchiq-driver.patch +++ b/target/linux/brcm2708/patches-4.4/0036-bcm2708-vchiq-driver.patch @@ -1848,7 +1848,7 @@ vchiq: hack: Add include depecated dma include file +#endif /* VCHIQ_2835_H */ --- /dev/null +++ b/drivers/misc/vc04_services/interface/vchiq_arm/vchiq_2835_arm.c -@@ -0,0 +1,586 @@ +@@ -0,0 +1,585 @@ +/** + * Copyright (c) 2010-2012 Broadcom.
