Integrate spec files and activate emulator-kernel.spec
This PR is to remove unnecessary and duplicated spec files.
And, it is to activate the kernel image (bzImage) and System
map file (System.map) with gbs build as well as build scripts
such as build_x86.sh and build_x86_64.sh.
**Changes proposed in this PR:**
* Changelog v3:
1. Appended symbolic link with /usr/src/linux-headers for compatibility
* Changelog v2:
1. Applied the comments of @Mikhail Labiuk and @MyungJoo Ham
* Changelog v1:
1. bzImage is used to run emulator rootfs based on QEMU/KVM
2. System.map is used to do debugging kernel functions
3. Removed unnecessary spec files
4. Integrated the spec files into one spec file for consistency
5. Added kernel-headers rpm to support kernel module build of arm/aarch64
**Self assessment:**
1. GBS build: Passed
1. OBS build: Passed (manually)
**How to evaluate:**
1. x86/32bit: time gbs build -A i586 --clean --include-all --define "with emulator"
2. x86/64bit: time gbs build -A x86_64 --clean --include-all --define "with emulator"
3. arm/32bit: time gbs build -A armv7l --clean --include-all --define "with emulator"
4. arm/64bit: time gbs build -A aarch64 --clean --include-all --define "with emulator"

Smack: Signal delivery as an append operation
Under a strict subject/object security policy delivering a
signal or delivering network IPC could be considered either
a write or an append operation. The original choice to make
both write operations leads to an issue where IPC delivery
is desired under policy, but delivery of signals is not.
This patch provides the option of making signal delivery
an append operation, allowing Smack rules that deny signal
delivery while allowing IPC. This was requested for Tizen.

Smack: fix d_instantiate logic for sockfs and pipefs
Since
4b936885a (v2.6.32) all inodes on sockfs and pipefs are disconnected.
It caused filesystem specific code in smack_d_instantiate to be skipped,
because all inodes on those pseudo filesystems were treated as root inodes.
As a result all sockfs inodes had the Smack label set to floor.
In most cases access checks for sockets use socket_smack data so the inode
label is not important. But there are special cases that were broken.
One example would be calling fcntl with F_SETOWN command on a socket fd.
Now smack_d_instantiate expects all pipefs and sockfs inodes to be
disconnected and has the logic in appropriate place.

When there is a CM id object that has port assigned to it, it means that

that port was removed (hot-unplug event) the cm-id was not updated.
In order to fix that the port keeps a list of all the cm-id's that are

multiple CQEs from residing in a 128B cache line,

PM / sleep: don't suspend parent when async child suspend_{noirq, late} fails
commit
6f75c3fd56daf547d684127a7f83c283c3c160d1 upstream.
Consider two devices, A and B, where B is a child of A, and B utilizes
asynchronous suspend (it does not matter whether A is sync or async). If
B fails to suspend_noirq() or suspend_late(), or is interrupted by a
wakeup (pm_wakeup_pending()), then it aborts and sets the async_error
variable. However, device A does not (immediately) check the async_error
variable; it may continue to run its own suspend_noirq()/suspend_late()
callback. This is bad.
We can resolve this problem by doing our error and wakeup checking
(particularly, for the async_error flag) after waiting for children to
suspend, instead of before. This also helps align the logic for the noirq and
late suspend cases with the logic in __device_suspend().
It's easy to observe this erroneous behavior by, for example, forcing a
device to sleep a bit in its suspend_noirq() (to ensure the parent is
waiting for the child to complete), then return an error, and watch the
parent suspend_noirq() still get called. (Or similarly, fake a wakeup
event at the right (or is it wrong?) time.)

RTC can be clocked from an external 32KHz oscillator, or from the

The RTC functional clock is sourced by default from the clock derived
from the Peripheral PLL. In order to select source as external osc clk
the following changes needs to be done:

- Enable the clock mux(RTC_OSC_REG[6]K32CLK_EN = 1)
- Select the external clock source (RTC_OSC_REG[3]32KCLK_SEL = 1)

drm/amdgpu: Attach exclusive fence to prime exported bo's. (v5)
commit
8e94a46c1770884166b31adc99eba7da65a446a7 upstream.
External clients which import our bo's wait only
for exclusive dmabuf-fences, not on shared ones,
ditto for bo's which we import from external
providers and write to.
Therefore attach exclusive fences on prime shared buffers
if our exported buffer gets imported by an external
client, or if we import a buffer from an external
exporter.
See discussion in thread:
https://lists.freedesktop.org/archives/dri-devel/2016-October/122370.html
Prime export tested on Intel iGPU + AMD Tonga dGPU as
DRI3/Present Prime render offload, and with the Tonga
standalone as primary gpu.
v2: Add a wait for all shared fences before prime export,
as suggested by Christian Koenig.
v3: - Mark buffer prime_exported in amdgpu_gem_prime_pin,
so we only use the exclusive fence when exporting a
bo to external clients like a separate iGPU, but not
when exporting/importing from/to ourselves as part of
regular DRI3 fd passing.
- Propagate failure of reservation_object_wait_rcu back
to caller.
v4: - Switch to a prime_shared_count counter instead of a
flag, which gets in/decremented on prime_pin/unpin, so
we can switch back to shared fences if all clients
detach from our exported bo.
- Also switch to exclusive fence for prime imported bo's.
v5: - Drop lret, instead use int ret -> long ret, as proposed
by Christian.

So Sebastian turned off the PIE for kernel builds but that was too late
- Kbuild.include already uses KBUILD_CFLAGS and trying to disable gcc
options with, say cc-disable-warning, fails:

/dev/null:1:0: error: code model kernel does not support PIC mode
because that returns an error and we can't disable the warning. For
example in this case:
KBUILD_CFLAGS += $(call cc-disable-warning,frame-address,)
which leads to gcc issuing all those warnings again.
So let's turn off PIE/PIC at the earliest possible moment, when we
declare KBUILD_CFLAGS so that cc-disable-warning picks it up too.
Also, we need the $(call cc-option ...) because -fno-PIE is supported
since gcc v3.4 and our lowest supported gcc version is 3.2 right now.

mfd: intel-lpss: Do not put device in reset state on suspend

Commit
41a3da2b8e163 ("mfd: intel-lpss: Save register context on
suspend") saved the register context while going to suspend and
also put the device in reset state.
Due to the resetting of device, system cannot enter S3/S0ix
states when no_console_suspend flag is enabled. The system
and serial console both hang. The resetting of device is not
needed while going to suspend. Hence remove this code.

x86/cpu/AMD: Fix cpu_llc_id for AMD Fam17h systems
commit
b0b6e86846093c5f8820386bc01515f857dd8faa upstream.
cpu_llc_id (Last Level Cache ID) derivation on AMD Fam17h has an
underflow bug when extracting the socket_id value. It starts from 0
so subtracting 1 from it will result in an invalid value. This breaks
scheduling topology later on since the cpu_llc_id will be incorrect.
For example, the the cpu_llc_id of the *other* CPU in the loops in
set_cpu_sibling_map() underflows and we're generating the funniest
thread_siblings masks and then when I run 8 threads of nbench, they get
spread around the LLC domains in a very strange pattern which doesn't
give you the normal scheduling spread one would expect for performance.
Other things like EDAC use cpu_llc_id so they will be b0rked too.
So, the APIC ID is preset in APICx020 for bits 3 and above: they contain
the core complex, node and socket IDs.
The LLC is at the core complex level so we can find a unique cpu_llc_id
by right shifting the APICID by 3 because then the least significant bit
will be the Core Complex ID.

sparc64: Handle extremely large kernel TLB range flushes more gracefully.
[ Upstream commit
a74ad5e660a9ee1d071665e7e8ad822784a2dc7f ]
When the vmalloc area gets fragmented, and because the firmware
mapping area sits between where modules live and the vmalloc area, we
can sometimes receive requests for enormous kernel TLB range flushes.
When this happens the cpu just spins flushing billions of pages and
this triggers the NMI watchdog and other problems.
We took care of this on the TSB side by doing a linear scan of the
table once we pass a certain threshold.
Do something similar for the TLB flush, however we are limited by
the TLB flush facilities provided by the different chip variants.
First of all we use an (mostly arbitrary) cut-off of 256K which is
about 32 pages. This can be tuned in the future.
The huge range code path for each chip works as follows:
1) On spitfire we flush all non-locked TLB entries using diagnostic
acceses.
2) On cheetah we use the "flush all" TLB flush.
3) On sun4v/hypervisor we do a TLB context flush on context 0, which
unlike previous chips does not remove "permanent" or locked
entries.
We could probably do something better on spitfire, such as limiting
the flush to kernel TLB entries or even doing range comparisons.
However that probably isn't worth it since those chips are old and
the TLB only had 64 entries.

sparc64 mm: Fix base TSB sizing when hugetlb pages are used
[ Upstream commit
af1b1a9b36b8f9d583d4b4f90dd8946ed0cd4bd0 ]
do_sparc64_fault() calculates both the base and huge page RSS sizes and
uses this information in calls to tsb_grow(). The calculation for base
page TSB size is not correct if the task uses hugetlb pages. hugetlb
pages are not accounted for in RSS, therefore the call to get_mm_rss(mm)
does not include hugetlb pages. However, the number of pages based on
huge_pte_count (which does include hugetlb pages) is subtracted from
this value. This will result in an artificially small and often negative
RSS calculation. The base TSB size is then often set to max_tsb_size
as the passed RSS is unsigned, so a negative value looks really big.
THP pages are also accounted for in huge_pte_count, and THP pages are
accounted for in RSS so the calculation in do_sparc64_fault() is correct
if a task only uses THP pages.
A single huge_pte_count is not sufficient for TSB sizing if both hugetlb
and THP pages can be used. Instead of a single counter, use two: one
for hugetlb and one for THP.

tcp: take care of truncations done by sk_filter()
[ Upstream commit
ac6e780070e30e4c35bd395acfe9191e6268bdd3 ]
With syzkaller help, Marco Grassi found a bug in TCP stack,
crashing in tcp_collapse()
Root cause is that sk_filter() can truncate the incoming skb,
but TCP stack was not really expecting this to happen.
It probably was expecting a simple DROP or ACCEPT behavior.
We first need to make sure no part of TCP header could be removed.
Then we need to adjust TCP_SKB_CB(skb)->end_seq
Many thanks to syzkaller team and Marco for giving us a reproducer.

ipv4: use new_gw for redirect neigh lookup
[ Upstream commit
969447f226b451c453ddc83cac6144eaeac6f2e3 ]
In v2.6, ip_rt_redirect() calls arp_bind_neighbour() which returns 0
and then the state of the neigh for the new_gw is checked. If the state
isn't valid then the redirected route is deleted. This behavior is
maintained up to v3.5.7 by check_peer_redirect() because rt->rt_gateway
is assigned to peer->redirect_learned.a4 before calling
ipv4_neigh_lookup().
After commit
5943634fc559 ("ipv4: Maintain redirect and PMTU info in
struct rtable again."), ipv4_neigh_lookup() is performed without the
rt_gateway assigned to the new_gw. In the case when rt_gateway (old_gw)
isn't zero, the function uses it as the key. The neigh is most likely
valid since the old_gw is the one that sends the ICMP redirect message.
Then the new_gw is assigned to fib_nh_exception. The problem is: the
new_gw ARP may never gets resolved and the traffic is blackholed.
So, use the new_gw for neigh lookup.
Changes from v1:
- use __ipv4_neigh_lookup instead (per Eric Dumazet).

net: __skb_flow_dissect() must cap its return value
[ Upstream commit
34fad54c2537f7c99d07375e50cb30aa3c23bd83 ]
After Tom patch, thoff field could point past the end of the buffer,
this could fool some callers.
If an skb was provided, skb->len should be the upper limit.
If not, hlen is supposed to be the upper limit.
