Bananymous	531f470132	Kernel: Add helper to map pages with base address and size ... This allows us to easily map enough pages for buffer with known size VESA driver can now allocate enough memory for whole framebuffer if it doesn't fit in a single page (1920x1080 for example)	2023-01-05 03:44:41 +02:00
