Andreas Kling	9e55bcb7da	Kernel: Make kernel memory regions be non-executable by default ... From now on, you'll have to request executable memory specifically if you want some.	2019-12-25 22:41:34 +01:00
Andreas Kling	078ee798f7	Kernel: Bump KBufferBuilder VM allocation to 4 MB ... This is pretty large but since it's not eagerly committed to physical pages, it's probably okay. I'm bumping this after running out of space for a ProtocolServer profile run :^)	2019-12-12 21:58:32 +01:00
Andreas Kling	f083031a27	Kernel: Add KBufferBuilder, similar to StringBuilder but for KBuffer ... This class works by eagerly allocating 1MB of virtual memory but only adding physical pages on demand. In other words, when you append to it, its memory usage will increase by 1 page whenever you append across a page boundary (4KB.)	2019-08-06 20:04:12 +02:00
