Add support for non ACPI system, such as system that uses Advanced Boot

with PINCTRL/GPIO.

We only support breakpoint/watchpoint of length 1, 2, 4 and 8. If we can
support other length as well, then user may watch more data with less
number of watchpoints (provided hardware supports it). For example: if we
have to watch only 4th, 5th and 6th byte from a 64 bit aligned address, we

ARM64 hardware expects 64bit aligned address for watchpoint invocation.
However, it provides byte selection method to select any number of
consecutive byte set within the range of 1-8.
This patch adds support to test all such byte selection option for
different memory write sizes.
Signed-off-by:
ARM64 hardware supports watchpoint at any double word aligned address.
However, it can select any consecutive bytes from offset 0 to 7 from that
base address. For example, if base address is programmed as 0x420030 and
byte select is 0x1C, then access of 0x420032,0x420033 and 0x420034 will
generate
Since, arm64 can support all offset within a double word limit. Therefore,
now support other lengths within that range as well.

Currently, unreserve_highatomic_pageblock bails out if it found

This patch makes unreserve functions bail out only if it moves
some pages out of !
In page freeing path, migratetype is racy so that a highorderatomic
page could free into non-highorderatomic free list. If that page
is allocated, VM can change the pageblock from higorderatomic to
something. In that case, highatomic pageblock accounting is broken
so it doesn't work(e.g., VM cannot

The generic opp_set_rate() handler isn't sufficient for platforms with

The return value 0 from acpi_register_gsi() means irq mapping failed.
So, we should process this case in else branch.

Since mmaped pages will be accounted by the PSS, memtrack needs a way
to differentiate the total memory that hasn't been accounted for.

Shared-buffer allocators like ion or GEM traditionally call into CMA or
alloc_pages() to get backing memory, meaning these allocations will not
show up in any process's mm counters. But since these allocations are

When a process is forked, all the buffers are shared with the forked

This patchstack introduces a new "memtrack" module for tracking and accounting
memory exported to userspace as shared buffers, like dma-buf fds or GEM handles.
Any process holding a reference to these buffers will keep the kernel from
reclaiming its backing pages. mm counters don't provide a comp
These optional file_operations notify a file implementation when it is
installed or uninstalled from a task's fd table. This can be used for
accounting of file-backed shared resources like dma-buf.
This involves some changes to the __fd_install() and __close_fd() APIs
to actually pass along the r
The Lenovo Yoga 910-13IKB does not have a hw rfkill switch, and trying
to read the hw rfkill switch through the ideapad module causes it to
always report as blocked.
This commit adds the Lenovo Yoga 910-13IKB to the no_hw_rfkill dmi list,
fixing the WiFI breakage.

("perf/core: Set cgroup in CPU contexts for new cgroup events")
fails to verify that event->cgrp is actually the scheduled cgroup
in a CPU before setting cpuctx->cgrp. This patch fixes that.
The bug only impacts the first cgroup that is created in a CPU.
