clean up names related to socket filtering and bpf in the following way:
- everything that deals with sockets keeps 'sk_*' prefix
- everything that is pure BPF is changed to 'bpf_*' prefix
split 'struct sk_filter' into
struct sk_filter {
atomic_t refcnt;
struct rcu_head rcu;
struct bpf_prog *prog;
};
and
struct bpf_prog {
u32 jited:1,
len:31;
struct sock_fprog_kern *orig_prog;
unsigned int (*bpf_func)(const struct sk_buff *skb,
const struct bpf_insn *filter);
union {
struct sock_filter insns[0];
struct bpf_insn insnsi[0];
struct work_struct work;
};
};
so that 'struct bpf_prog' can be used independent of sockets and cleans up
'unattached' bpf use cases
split SK_RUN_FILTER macro into:
SK_RUN_FILTER to be used with 'struct sk_filter *' and
BPF_PROG_RUN to be used with 'struct bpf_prog *'
__sk_filter_release(struct sk_filter *) gains
__bpf_prog_release(struct bpf_prog *) helper function
also perform related renames for the functions that work
with 'struct bpf_prog *', since they're on the same lines:
sk_filter_size -> bpf_prog_size
sk_filter_select_runtime -> bpf_prog_select_runtime
sk_filter_free -> bpf_prog_free
sk_unattached_filter_create -> bpf_prog_create
sk_unattached_filter_destroy -> bpf_prog_destroy
sk_store_orig_filter -> bpf_prog_store_orig_filter
sk_release_orig_filter -> bpf_release_orig_filter
__sk_migrate_filter -> bpf_migrate_filter
__sk_prepare_filter -> bpf_prepare_filter
API for attaching classic BPF to a socket stays the same:
sk_attach_filter(prog, struct sock *)/sk_detach_filter(struct sock *)
and SK_RUN_FILTER(struct sk_filter *, ctx) to execute a program
which is used by sockets, tun, af_packet
API for 'unattached' BPF programs becomes:
bpf_prog_create(struct bpf_prog **)/bpf_prog_destroy(struct bpf_prog *)
and BPF_PROG_RUN(struct bpf_prog *, ctx) to execute a program
which is used by isdn, ppp, team, seccomp, ptp, xt_bpf, cls_bpf, test_bpf

Pull Exynos platform DT fix from Grant Likely:
"Device tree Exynos bug fix for v3.16-rc7
This bug fix has been brewing for a while. I hate sending it to you
so late, but I only got confirmation that it solves the problem this
past weekend. The diff looks big for a bug fix, but the majority of
it is only executed in the Exynos quirk case. Unfortunately it
required splitting early_init_dt_scan() in two and adding quirk
handling in the middle of it on ARM.
Exynos has buggy firmware that puts bad data into the memory node.
Commit 1c2f87c22566 ("ARM: Get rid of meminfo") exposed the bug by
dropping the artificial upper bound on the number of memory banks that
can be added. Exynos fails to boot after that commit. This branch
fixes it by splitting the early DT parse function and inserting a
fixup hook. Exynos uses the hook to correct the DT before parsing
memory regions"

* tag 'stable/for-linus-3.16-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
x86/xen: safely map and unmap grant frames when in atomic context
|
|
arch_gnttab_map_frames() and arch_gnttab_unmap_frames() are called in
atomic context but were calling alloc_vm_area() which might sleep.
Also, if a driver attempts to allocate a grant ref from an interrupt
and the table needs expanding, then the CPU may already by in lazy MMU
mode and apply_to_page_range() will BUG when it tries to re-enable
lazy MMU mode.
These two functions are only used in PV guests.
Introduce arch_gnttab_init() to allocates the virtual address space in
advance.
Avoid the use of apply_to_page_range() by using saving and using the
array of PTE addresses from the alloc_vm_area() call (which ensures
that the required page tables are pre-allocated).

Commit 1c2f87c22566cd057bc8cde10c37ae9da1a1bb76
(ARM: 8025/1: Get rid of meminfo) dropped the upper bound on
the number of memory banks that can be added as there was no
technical need in the kernel. It turns out though, some bootloaders
(specifically the arndale-octa exynos boards) may pass invalid memory
information and rely on the kernel to not parse this data. This is a
bug in the bootloader but we still need to work around this.
Work around this by introducing a dt_fixup function. This function
gets called before the flattened devicetree is scanned for memory
and the like. In this fixup function for exynos, limit the maximum
number of memory regions in the devicetree.

Commit 9188883fd66e9 (ARM: dts: Enable twl4030 off-idle configuration
for selected omaps) allowed n900 to cut off core voltages during
off-idle. This however caused a regression where twl regulator
vaux1 was not getting enabled for the LCD panel as we are not
requesting it for the panel.
Turns out quite a few devices on n900 are using vaux1, and we need
to either stop idling it, or add proper regulator_get calls for all
users. But until we have a proper solution implemented and tested,
let's just disable the twl off-idle configuration for now for n900.

When CPU topology is specified in device tree, cpu_logical_map() does
not return core ID anymore, but rather full MPIDR value. This breaks
existing calculation of PMU register offsets on Exynos SoCs.
This patch fixes the problem by adjusting the code to use only core ID
bits of the value returned by cpu_logical_map() to allow CPU topology to
be specified in device tree on Exynos SoCs.

The i.MX6 reference manual doesn't make a clear distinction
between the fixed clock divider and the enable gate for the
pcie and sata reference clocks. This lead to the lvds mux
inputs in the imx6q clk driver to be parented from the
ref clock (which is the divider) instead of the actual gate,
which in turn prevents the upstream clock to actually be
enabled when lvds clk out is active.
This fixes a hard machine hang regression in kernel 3.16 for
boards where only pcie is active but no sata, as with this
kernel version the imx6-pcie driver is no longer enabling
the upstream clock directly but only lvds clk out.

On OMAP SOCs using PL310 controllers, power_ctrl register is not
accessible from non-secure software even on PL310 versions which
support it. The secure code takes care of setting it up correctly
and power transitions are proven on these devices.
For example, AM437x has L2C-310 version r3p3 and ROM code on that
device does not support writing to L2C-310 power control register.
The L2C driver, however, tries writing to this register for all
revisions >= r3p0.
This leads to a warning dump on boot which leads most users to believe
that L2 cache is non-functional.
Since the problem is understood, and cannot be addressed through
software, replace the warning with a pr_info() while maintaining the
WARN_ON() for other truly unexpected scenarios.

Currently, the exynos cpuidle driver works correctly only on exynos4210
and 5250. Trying to use it with just one CPU online on any other exynos
SoCs will lead to system failure, due to unsupported AFTR mode on other
SoCs. This patch fixes the problem by registering the driver only on
supported SoCs and letting others simply use default WFI mode until
support for them is added.

While powering on/off a local powerdomain in exynos5 chipsets, the
input clocks to each device gets modified. This behaviour is based
on the SYSCLK_SYS_PWR_REG registers.
E.g. SYSCLK_MFC_SYS_PWR_REG = 0x0, the parent of input clock to MFC
(aclk333) gets modified to oscclk
= 0x1, no change in clocks.
The recommended value of SYSCLK_SYS_PWR_REG before power gating any
domain is 0x0. So we must also restore the clocks while powering on
a domain everytime.
This patch adds the framework for getting the required mux and parent
clocks through a power domain device node. With this patch, while
powering off a domain, parent is set to oscclk and while powering back
on, its re-set to the correct parent which is as per the recommended
pd on/off sequence.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Merge "omap fixes against v3.16-rc4" from Tony Lindgren:
Fixes for omaps for the -rc series. It's mostly fixes for clock rates,
restart handling and phy regulators and SATA interconnect data.
Also few build fixes related to the DSP driver in staging, and trivial
stuff like removal of broken and soon to be unused platform data init
for HDMI audio that would be good to get into the -rc series if not
too late.

Currently, the coherency fabric support registers two bus notifiers;
one for platform, one for pci bus types, with the same notifier block.
However, this is illegal and can cause serious issues: the notifier
block is also a link in the notifier list and cannot be inserted twice.
This commit fixes this by using different notifier blocks (with the same
notifier callback) to set the platform and pci bus types notifiers.

armada_370_xp_pmsu_idle_enter
In the inline asm part of the function armada_370_xp_pmsu_idle_enter()
the input operand was used. The intent here was to let the compiler
choose this register so it could do the optimization it
needed.
However an input operand is not supposed to be modified by the inline
asm code. This can lead to improper generated instructions.
In some case generated instruction the compiler made the choice to
reuse the same register to store the return value. But in the assembly
part this register was modified, so it can lead to return an wrong
value.
The fix is to use a clobber. Thanks to this the compiler will know
that the value of this register will be modified.

Let's say clock A and B are two gate clocks that share the same register
bit in hardware. Therefore they are registered as shared gate clocks
with imx_clk_gate2_shared().
In a scenario that only clock A is enabled by clk_enable(A) while B is
not used, the shared gate will be unexpectedly disabled in hardware.
It happens because clk_enable(A) increments the share_count from 0 to 1,
while clock B is unused to clock core, and therefore the core function
will just disable B by calling clk->ops->disable() directly. The
consequence of that call is share_count is decremented to 0 and the gate
is disabled in hardware, even though clock A is still in use.
The patch fixes the issue by initializing the share_count per hardware
state and returns enable state per share_count from .is_enabled() hook,
in case it's a shared gate.
While at it, add a check in clk_gate2_disable() to ensure it's never
called with a zero share_count.

Currently CLK_FOUT_EPLL was set as one of the parents of AUDSS mux.
As per the user manual, it should be CLK_MAU_EPLL.
The problem surfaced when the bootloader in Peach-pit board set
the EPLL clock as the parent of AUDSS mux. While booting the kernel,
we used to get a system hang during late boot if CLK_MAU_EPLL was
disabled.
