Although unbinding a driver requires root privileges but it still might be used theoretically in certain attacks (by triggering NULL pointer exception or memory corruption if driver does not provide proper remove callbacks or core does not handle it). Samsung clock drivers are essential for system operation so their removal is not expected. More over, the Exynos3250 ISP clock driver does not implement remove() driver callback and it is not buildable as modules. Suppress the unbind interface for Exynos3250 ISP and S3C2410 DCLK clock drivers. Suggested-by:

The aclk333 clock needs to be ungated during the MFC power domain switch, so set the clock ID to allow the Exynos power domain logic to lookup this clock if is defined in the MFC PD device tree node. Signed-off-by:

The PNAME macro defines array of strings for names of mux parents. Although the strings itself were const but pointers to them were not thus this data resided in initdata. Make this an array of const pointers to const strings and move to initconst section. Signed-off-by:

The original name was simply hash_string(), but that conflicted with a function with that name in drivers/base/power/trace.c, and I decided that calling it "hashlen_" was better anyway. But you have to do it in two places. [ This caused build errors for architectures that don't define CONFIG_DCACHE_WORD_ACCESS - Linus ] Signed-off-by:

The HPFS filesystem used generic_show_options to produce string that is displayed in /proc/mounts. However, there is a problem that the options may disappear after remount. If we mount the filesystem with option1 and then remount it with option2, /proc/mounts should show both option1 and option2, however it only shows option2 because the whole option string is replaced with replace_mount_options in hpfs_remount_fs. To fix this bug, implement the hpfs_show_options function that prints options that are currently selected. Signed-off-by:

Commit c8f33d0b ("affs: kstrdup() memory handling") checks if the kstrdup function returns NULL due to out-of-memory condition. However, if we are remounting a filesystem with no change to filesystem-specific options, the parameter data is NULL. In this case, kstrdup returns NULL (because it was passed NULL parameter), although no out of memory condition exists. The mount syscall then fails with ENOMEM. This patch fixes the bug. We fail with ENOMEM only if data is non-NULL. The patch also changes the call to replace_mount_options - if we didn't pass any filesystem-specific options, we don't call replace_mount_options (thus we don't erase existing reported options).
