[1116/1285] Replace numeric parameter like 0444 with macro

I find that the developers often just specified the numeric value
when calling a macro which is defined with a parameter for access permission.
As we know, these numeric value for access permission have had the corresponding macro,
and that using macro can improve the robustness and readability of the code,
thus, I suggest replacing the numeric parameter with the macro.

We have S_IRUGO for this.

Aye, for further edification, Baole, please read include/linux/stat.h,
particularly this part:

#define S_IRWXUGO       (S_IRWXU|S_IRWXG|S_IRWXO)
#define S_IALLUGO       (S_ISUID|S_ISGID|S_ISVTX|S_IRWXUGO)
#define S_IRUGO         (S_IRUSR|S_IRGRP|S_IROTH)
#define S_IWUGO         (S_IWUSR|S_IWGRP|S_IWOTH)
#define S_IXUGO         (S_IXUSR|S_IXGRP|S_IXOTH)

I suspect many of the patches in this set should be using one of the above
defines instead, never mind the ridiculousness of firing off such a
massive set at once, with every patch having the same (often not correct)
title, and the highly questionable benefit of the set to begin with.
