Add a check if crashk_res_low exists just like GART region does. If
crashk_res_low doesn't exist, calling exclude_mem_range is unnecessary.
Meanwhile, since crashk_res_low has been initialized at definition, it's
safe just use "if (crashk_low_res.end)" to check if it's exist. And this
can make it
In locate_mem_hole functions, a memory hole is located and added as

When a process triggers a page fault and kernel keeps
trying to retry the fault, there is no chance for this process
to be frozen, so the freeze request will always be pending.
This patch lets the page fault handler check pending
freeze request and freeze current process if so.

Ok if the crypto request_module is changed it makes more sense to
change zpool's use of request_module; it looks like there are a couple
other places in the kernel using prefixes/aliases (although it's not
universal). I still suggest moving the MODULE_ALIAS() into
zbud/zsmalloc's #ifdef

HSW-EP has a larger offcore mask than the client Haswell CPUs.
It is the same mask as on Sandy/IvyBridge-EP. All of
Haswell was using the client mask, so some bits were missing.
On the client parts some bits were also missing compared
to Sandy/IvyBridge, in particular the bits

One of the more common algorithms used for allocation
is to align the start address of the allocation to
the order of size requested. Add this as an algorithm
option for genalloc.

ARM currently uses a bitmap for tracking atomic allocations.
genalloc already handles this type of memory pool allocation
so switch to using that instead.

Neither CMA nor noncoherent allocations support atomic allocations.
Add a dedicated atomic pool to support this.

After allocating an address from a particular genpool,
there is no good way to verify if that address actually
belongs to a genpool. Introduce addr_in_gen_pool which
will return if an address plus size falls completely
within the genpool range.

Hi,
This is v7 of the series to add an atomic pool for arm64 and refactor some

Hi Linus,
Two EFI-related Kconfig changes, which happen to touch immediately

Hi Linus,
This is a patchset to support the XSAVES instruction required to
support context switch of supervisor-only features in upcoming
silicon. This patchset missed the 3.16 merge window, which is why it
