struct bfin_serial_port contains structs circ_buf, timer_list, and
work_struct directly (not pointers). This means that these structures
have to be defined completely to be inlined in struct
bfin_serial_port.
So instead of struct declarations, define the structures by including
proper headers. They were pulled in by linux/serial_core.h or others
until now. But experimenting with circ_buf removal from serial_core,
struct circ_buf becomes undefined in bfin_serial:

Although the tty core maintains a pid reference for the foreground
process group, if the foreground process group is changed that
pid reference is dropped. Thus, the pid reference used for signalling
could become stale.
Safely obtain a pid reference to the foreground process group and
release the reference after signalling is complete.

usb: patches for v3.19 merge window
This time, a very pull request with 216 non-merge
commits. Most of the commits contained here are
sparse or coccinelle fixes ranging from missing
'static' to returning 0 in case of errors.
More importantly, we have the removal the now
unnecessary 'driver' argument to ->udc_stop().
DWC2 learned about Dual-Role builds. Users of
this IP can now have a single driver built for
host and device roles.
DWC3 got support for two new HW platforms: Exynos7
and AMD.
The Broadcom USB 3.0 Device Controller IP is now
supported and so is PLX USB338x, which means DWC3
has lost is badge as the only USB 3.0 peripheral
IP supported on Linux.
Thanks for Tony Lindgren's work, we can now have
a distro-like kernel where all MUSB glue layers
can be built into the same kernel (statically
or dynamically linked) and it'll work in PIO (DMA
will come probably on v3.20).
Other than these, the usual set of cleanups and
non-critical fixes.

Whenever Suspend PHY bit is set on AM437x devices,
USB will not work due to Set EP Configuration command
always failing.
This was only found after a recent commit 2164a47 (usb:
dwc3: set SUSPHY bit for all cores, which will be merged
for v3.19) added a missing *required* step to dwc3
initialization. Synopsys Databook requires that we enable
Suspend PHY bit after initialization but that, unfortunately,
breaks AM437x.

Users have no business installing custom code segments into the
GDT, and segments that are not present but are otherwise valid
are a historical source of interesting attacks.
For completeness, block attempts to set the L bit. (Prior to
this patch, the L bit would have been silently dropped.)
This is an ABI break. I've checked glibc, musl, and Wine, and
none of them look like they'll have any trouble.
Note to stable maintainers: this is a hardening patch that fixes
no known bugs. Given the possibility of ABI issues, this
probably shouldn't be backported quickly.

Installing a 16-bit RW data segment into the GDT defeats espfix.
AFAICT this will not affect glibc, Wine, or dosemu at all.

in order to look at compiler output.
Since asm-offsets_{32,64}.c are included by asm-offsets.c and
building them directly doesn't evaluate the macros used (thus
making the preprocessor output not very useful), error out when
an attempt is made to build them. Issue a hint for the user to
build asm-offsets.c instead.

Otherwise, if buggy user code points DS or ES into the TLS
array, they would be corrupted after a context switch.
This also significantly improves the comments and documents some
gotchas in the code.

patch, the es test passes, although the gsbase test still fails.

This is the usual physical memory layout boot printout:
...
[ 0.000000] Zone ranges:
[ 0.000000] DMA [mem 0x00001000-0x00ffffff]
[ 0.000000] DMA32 [mem 0x01000000-0xffffffff]
[ 0.000000] Normal [mem 0x100000000-0xc3fffffff]
[ 0.000000] Movable zone start for each node
[ 0.000000] Early memory node ranges
[ 0.000000] node 0: [mem 0x00001000-0x00099fff]
[ 0.000000] node 0: [mem 0x00100000-0xbf78ffff]
[ 0.000000] node 0: [mem 0x100000000-0x63fffffff]
[ 0.000000] node 1: [mem 0x640000000-0xc3fffffff]
...
This is the log when we set "mem=2G" on the boot cmdline:
...
[ 0.000000] Zone ranges:
[ 0.000000] DMA [mem 0x00001000-0x00ffffff]
[ 0.000000] DMA32 [mem 0x01000000-0xffffffff] // should be 0x7fffffff, right?
[ 0.000000] Normal empty
[ 0.000000] Movable zone start for each node
[ 0.000000] Early memory node ranges
[ 0.000000] node 0: [mem 0x00001000-0x00099fff]
[ 0.000000] node 0: [mem 0x00100000-0x7fffffff]
...
This patch fixes the printout, the following log shows the right
ranges:
...
[ 0.000000] Zone ranges:
[ 0.000000] DMA [mem 0x00001000-0x00ffffff]
[ 0.000000] DMA32 [mem 0x01000000-0x7fffffff]
[ 0.000000] Normal empty
[ 0.000000] Movable zone start for each node
[ 0.000000] Early memory node ranges
[ 0.000000] node 0: [mem 0x00001000-0x00099fff]
[ 0.000000] node 0: [mem 0x00100000-0x7fffffff]

Pull tracing fixes from Steven Rostedt:
"Here's two fixes:
1) Discovered by Fengguang Wu's tests. I changed the parameters to
the function graph x86 prepare_ftrace_return call but forgot to
update the call from entry_32 (i386 version). This patch corrects
that.
2) I was tracing some code and found that the sched_switch tracepoint
was showing tasks in the INTERRUPTIBLE state as RUNNING. This was
due to the updates to convert preempt_count into a per_cpu
variable. The tracepoint logic was made to use the tasks
saved_preempt_count which could hold a stale "PREEMPT_ACTIVE",
instead of using the current preempt_count() call"

tracing/sched: Check preempt_count() for current when reading task->state
ftrace/x86: Update i386 call to prepare_ftrace_return()

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
The parameters for prepare_ftrace_return() used by the function graph
tracer were swapped to simplify the code on x86_64. But i386 function
graph trampoline also calls this function, and it did not have its
parameters swapped.

Memset on a local variable may be removed when it is called just before the
variable goes out of scope. Using memzero_explicit defeats this
optimization. A simplified version of the semantic patch that makes this
change is as follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier x;
type T;
@@
{
... when any
T x[...];
... when any
when exists
- memset
+ memzero_explicit
(x,
-0,
...)
... when != x
when strict
}
