As part of initializing struct page's in 2MiB chunks, we noticed that
at the end of free_all_bootmem(), there was nothing which had forced
the reserved/allocated 4KiB pages to be initialized.
This helper function will be used for that expansion.

mminit_verify_page_links() is an extremely paranoid check that was introduced
when memory initialisation was being heavily reworked. Profiles indicated
that up to 10% of parallel memory initialisation was spent on checking
this for every page. The cost could be reduced but in practice this check

Parallel struct page frees pages one at a time. Try free pages as single

Only a subset of struct pages are initialised at the moment. When this patch
is applied kswapd initialise the remaining struct pages in parallel. This
should boot faster by spreading the work to multiple CPUs and initialising
data that is local to the CPU. The user-visible effect on large machines
The big change here is an adjustment to the topology_init path that caused
soft lockups on Waiman and Daniel Blue had reported it was an expensive

Currently, memmap_init_zone() has all the smarts for initializing a single

__free_pages_bootmem prepares a page for release to the buddy allocator

early_pfn_in_nid() and meminit_pfn_in_nid() are small functions that are

After commit 5d5d56897530 ("make new_sync_{read,write}() static")
->read() cannot be called directly.
kdbus_pool_slice_copy() leads to oops, which can be reproduced by

The slub_debug=PU,kmalloc-xx cannot work because in the
create_kmalloc_caches() the s->name is created after the
create_kmalloc_cache() is called. The name is NULL in the
create_kmalloc_cache() so the kmem_cache_flags() would not set the
slub_debug flags to the s->flags. The fix here set up a kmall

This is indeed how I implemented it initially. The nice thing
about this approach is tha
use the standard framebuffer_alloc() and framebuffer_release() instead
of custom defined function. for making that change we had to change a
member of the private structure from a variable to pointer and had to
touch almost all places of the file. since fb was changed into a pointer
