9879bbf646 vm: optimise page array size and initialisation.
* the page array now only extends up to the last non-reserved memory frame.
* rather than memset'ing the whole array to zero, we only initialise p_flags
  for each page in vm_page_array_init, and then leave it to group_pages_into_block
  to initialise the other parts of vm_page_t.

51ad3d48fd memblock: mark bytes preceding an aligned allocation as reserved.
this prevents tiny holes of free memory appearing between
blocks of aligned allocations.

0516ef06a3 vm: explicitly initialise kmalloc in vm_bootstrap
if kmalloc is called with count=N before vm_bootstrap is finished,
the request will be fulfilled using memblock_alloc.

if N is a power of 2, the returned pointer will be aligned to
an N-byte boundary.

fe0b7e043f x86_64: move stack pointer to higher-half in start_64 2023-02-06 20:50:38 +00:00
5c7bde4fdf vm: add alignment parameter to cache allocator
caches with object size N, where N is a power of two, will naturally
align their objects on N-byte boundaries.

all other caches will align to an 8-byte boundary by default.
