Andreas Kling 1593219a41 Kernel: Map signal trampoline into each process's address space 
The signal trampoline was previously in kernelspace memory, but with
a special exception to make it user-accessible.

This patch moves it into each process's regular address space so we
can stop supporting user-allowed memory above 0xc0000000.

SerenityOS

Graphical Unix-like operating system for x86 computers.

Build status Fuzzing Status

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
