Intel PT uses IP compression based on the last IP. For decoding purposes,
'last IP' is not updated when a branch target has been suppressed, which is
indicated by IPBytes == 0. IPBytes is stored in the packet 'count', so
ensure never to set 'last_ip' when packet 'count' is zero.

The decoder will try to use branch packets to find an IP to start decoding
or to recover from errors. Currently the FUP packet is used only in the
case of an overflow, however there is no reason for that to be a special
case. So just use FUP always when scanning for an IP.

Branch tracing is enabled by default, so a fake config bit called 'pt'
(pass-through) was added to allow the 'branch enable' bit to have affect.
Add default config 'pt,branch' which will allow users to disable branch
tracing using 'branch=0' instead of having to specify 'pt,branch=0'.

The kernel now supports the disabling of branch tracing, however the
decoder assumes branch tracing is always enabled. Pass through a parameter
to indicate whether branch tracing is enabled and use it to avoid cases
when the decoder is expecting branch packets. There are 2 such cases.
First, FUP
Intel PT uses IP compression based on the last IP. For decoding purposes,
'last IP' is considered to be reset to zero whenever there is a
synchronization packet (PSB). The decoder wasn't doing that, and was
treating the zero value to mean that there was no last IP, whereas
compression can be done

exposed in /usr/include/linux/uuid.h for some time.

structure pl111_display_funcs can be made static as it does not need to be
in global scope. Fixes sparse warning:
"warning: symbol 'pl111_display_funcs' was not declared. Should it
be static?"
Fixes: bed41005e6174d ("drm/pl111: Initial drm/kms driver for pl111")
This adds dt-binding documentation for Mediatek MT2712.
Only include very basic items: cpu, gic and uart.

Another thing that occurred to me while staring at that function, is

MT2712 is a SoC based on 64bit ARMv8 architecture.
MT2712 share many HW IP with MT8173. This patchset was tested
on MT2712 evaluation board, and boot to shell ok.
This series contains document bindings, device tree including
interrupt, uart.

Could you just use "int i". I know some static checkers complain but
those tools are dumb. I just fixed a couple bugs two days ago where

Hi,
this is a follow up for [1]. The first patch is what Tetsuo suggested
[2], I've just added a changelog for it. This one should be merged
as soon as possible. The second patch is still an RFC. I _believe_
that it is the right thing to do but I haven't checked all the PF paths
which return
From: Michal Hocko
Roman Gushchin has noticed that we kill two tasks when the memory hog
killed from page fault path:
[ 25.721494] allocate invoked oom-killer:
gfp_mask=0x14280ca(GFP_HIGHUSER_MOVABLE|__GFP_ZERO), nodemask=(null), order=0,
oom_score_adj=0

From: Michal Hocko
Any allocation failure during the #PF path will return with VM_FAULT_OOM
which in turn results in pagefault_out_of_memory. This can happen for
2 different reasons. a) Memcg is out of memory and we rely on
mem_cgroup_oom_synchronize to perform the memcg OOM handling or b)
