- mm: page_alloc: fix CMA area initialisation when pageblock > MAX_ORDER
-
- With a kernel configured with ARM64_64K_PAGES && !TRANSPARENT_HUGEPAGE,
- the following is triggered at early boot:
-
- SMP: Total of 8 processors activated.
- devtmpfs: initialized
- Unable to handle kernel NULL pointer dereference at virtual address 00000008
- pgd = fffffe0000050000
- [00000008] *pgd=00000043fba00003, *pmd=00000043fba00003, *pte=00e0000078010407
- Internal error: Oops: 96000006 [#1] SMP
- Modules linked in:
- CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.15.0-rc864k+ #44
- task: fffffe03bc040000 ti: fffffe03bc080000 task.ti: fffffe03bc080000
- PC is at __list_add+0x10/0xd4
- LR is at free_one_page+0x270/0x638

- [<fffffe00007520a0>] kernel_init+0xc/0xd4
-
- This happens because init_cma_reserved_pageblock() calls __free_one_page()
- with pageblock_order as page order but it is bigger than MAX_ORDER. This
- in turn causes accesses past zone->free_list[].
-
- Fix the problem by changing init_cma_reserved_pageblock() such that it
- splits pageblock into individual MAX_ORDER pages if pageblock is bigger
- than a MAX_ORDER page.
-
- In cases where !CONFIG_HUGETLB_PAGE_SIZE_VARIABLE, which is all
- architectures expect for ia64, powerpc and tile at the moment, the
- “pageblock_order > MAX_ORDER” condition will be optimised out since
- both sides of the operator are constants. In cases where pageblock size
- is variable, the performance degradation should not be significant anyway
- since init_cma_reserved_pageblock() is called only at boot time at most
- MAX_CMA_AREAS times which by default is eight.

-d911d9874801 ("kernfs: make kernfs_notify() trigger inotify events
-too") added fsnotify triggering to kernfs_notify() which requires a
-sleepable context. There are already existing users of
-kernfs_notify() which invoke it from an atomic context and in general
-it's silly to require a sleepable context for triggering a
-notification.
-
-The following is an invalid context bug triggerd by md invoking
-sysfs_notify() from IO completion path.

-This patch fixes it by punting the notification delivery through a
-work item. This ends up adding an extra pointer to kernfs_elem_attr
-enlarging kernfs_node by a pointer, which is not ideal but not a very
-big deal either. If this turns out to be an actual issue, we can move
-kernfs_elem_attr->size to kernfs_node->iattr later.
