01 init/目录下Kconfig修改：
956行添加：
config PANIC_TIMEOUT int "Default panic timeout" default 0 help Set default panic timeout.
02 drivers目录下Kconfig：
添加：
source "drivers/rongpin/Kconfig" source "drivers/switch/Kconfig" source "drivers/nfc/Kconfig" source "drivers/gud/Kconfig"
03 drivers目录下Makefile：
添加：
obj-$(CONFIG_SWITCH) += switch/ obj-$(CONFIG_MOBICORE_DRIVER) += gud/ obj-$(CONFIG_RPDZKJ_SYSFS) += rongpin/
04 drivers目录下：
将switch，gud，rongpin三个目录拷贝进来（对应原目录）

---------------------------------
法二：
（对比法）
荣品的内核源码和从官方下载的内核源码不一样的有如下文件：
一 ：arch
01◐arch主目录下：
①除arm、config其他全部删除
②修改config文件，在最后一行：source "kernel/gcov/Kconfig"
添加：
config HAVE_ARCH_SECCOMP_FILTER bool help An arch should select this symbol if it provides all of these things: - syscall_get_arch() - syscall_get_arguments() - syscall_rollback() - syscall_set_return_value() - SIGSYS siginfo_t support - secure_computing is called from a ptrace_event()-safe context - secure_computing return value is checked and a return value of -1 results in the system call being skipped immediately. config SECCOMP_FILTER def_bool y depends on HAVE_ARCH_SECCOMP_FILTER && SECCOMP && NET help Enable tasks to build secure computing environments defined in terms of Berkeley Packet Filter programs which implement task-defined system call filtering polices. See Documentation/prctl/seccomp_filter.txt for details. source "kernel/gcov/Kconfig"
02◐在arch/arm/configs下添加：
①exynos5_defconfig
②
二：block
1 blk-core.c文件：
①32行添加：
#include <linux/ratelimit.h> //add by phone at 20151117
②2122行：
switch (error) { case -ENOLINK: error_type = "recoverable transport"; break; case -EREMOTEIO: error_type = "critical target"; break; case -EBADE: error_type = "critical nexus"; break; case -EIO: default: error_type = "I/O"; break; } printk(KERN_ERR "end_request: %s error, dev %s, sector %llu\n", error_type, req->rq_disk ? req->rq_disk->disk_name : "?", (unsigned long long)blk_rq_pos(req)); }
换成：
switch (error) { case -ENOLINK: error_type = "recoverable transport"; break; case -EREMOTEIO: error_type = "critical target"; break; case -EBADE: error_type = "critical nexus"; break; case -ETIMEDOUT: error_type = "timeout"; break; case -ENOSPC: error_type = "critical space allocation"; break; case -ENODATA: error_type = "critical medium"; break; case -EIO: default: error_type = "I/O"; break; } printk_ratelimited(KERN_ERR "end_request: %s error, dev %s, sector %llu\n", error_type, req->rq_disk ? req->rq_disk->disk_name : "?", (unsigned long long)blk_rq_pos(req)); }
2 partition-genneric.c文件下：
①219行,添加：
static int part_uevent(struct device *dev, struct kobj_uevent_env *env) { struct hd_struct *part = dev_to_part(dev); add_uevent_var(env, "PARTN=%u", part->partno); if (part->info && part->info->volname[0]) add_uevent_var(env, "PARTNAME=%s", part->info->volname); return 0; }
②233行添加：
.uevent = part_uevent,
三：drivers
1 Makefile：
103行添加：
obj-$(CONFIG_SWITCH) += switch/
139行（最后添加）：
obj-$(CONFIG_MOBICORE_DRIVER) += gud/
obj-$(CONFIG_RPDZKJ_SYSFS) += rongpin/
2 Kconfig：
第3行添加：
source "drivers/rongpin/Kconfig" //add by phone at 20151117
第100行添加：
source "drivers/switch/Kconfig" //add by phone at 20151117
第146行添加：
source "drivers/nfc/Kconfig" source "drivers/gud/Kconfig"
3 将
四：include
五：kernel
六：lib
七：mm
八：net
九：security
