Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

The savings for copying just part of struct siginfo appears to be in the noise on modern machines. So remove this ``optimization'' and simplify the code. At the same time mark the second parameter as constant so there is no confusion as to which direction the copy will go. This ensures that a fully initialized siginfo that is sent ends up as a fully initialized siginfo on the signal queue. This full initialization ensures even confused code won't copy unitialized data to userspace, and it prepares for turning copy_siginfo_to_user into a simple copy_to_user. Signed-off-by: "Eric W.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
