The type of vma->vm_flags is 'unsigned long'. Neither 'int' nor
'unsigned int'. This patch fixes such misuse.

There is quite a lot of code which does copy_from_user() + strict_strto*()
or simple_strto*() combo in slightly different ways.
Before doing conversions all over tree, let's get final API correct.
Enter kstrtoull_from_user() and friends.
Typical code which uses them looks very simple:
TYPE val;
int rv;
rv = kstrtoTYPE_from_user(buf, count, 0, &val);
if (rv < 0)
return rv;
[use val]
return count;
There is a tiny semantic difference from the plain kstrto*() API -- the
latter allows any amount of leading zeroes, while the former copies data
into buffer on stack and thus allows leading zeroes as long as it fits
into buffer.
This shouldn't be a problem for typical usecase "echo 42 > /proc/x".
The point is to make reading one integer from userspace _very_ simple and
very bug free.
