The only difference between these two functions is that in activate_mm we
unconditionally flush context. However, there is no need to keep this

After a wrap (getting a new context version) a process must get a new
context id, which means that we would need to flush the context id from
the TLB before running for the first time with this ID on every CPU. But,
we use mm_cpumask to determine if this process has been running on this CPU
before, and this mask is not reset after a wrap. So, there are two possible
fixes for this issue:
1. Clear mm cpumask whenever mm gets a new context id
2. Unconditionally flush context every time process is running on a CPU
This patch implements the first solution

When a TSB grows beyond its current capacity, a new TSB is allocated
and copy_tsb is called to copy entries from the old TSB to the new.
A hash shift based on page size is used to calculate the index of an
entry in the TSB. copy_tsb has hard coded PAGE_SHIFT in these
calculations. However, for huge page TSBs the value REAL_HPAGE_SHIFT
should be used. As a result, when copy_tsb is called for a huge page
TSB the entries are placed at the incorrect index in the newly
allocated TSB. When doing hardware table walk, the MMU does not
match these entries and we end up in the TSB miss handling code.
This code will then create and write an entry to the correct index
in the TSB. We take a performance hit for the table walk miss and
recreation of these entries.
Pass a new parameter to copy_tsb that is the page size shift to be
used when copying the TSB.

Linux SPARC64 limits NR_CPUS to 4064 because init_cpu_send_mondo_info()
only allocates a single page for NR_CPUS mondo entries. Thus we cannot
use all 4096 CPUs on some SPARC platforms.
To fix, allocate (2^order) pages where order is set according to the size
of cpu_list for possible cpus. Since cpu_list_pa and cpu_mondo_block_pa
are not used in asm code, there are no imm13 offsets from the base PA
that will break because they can only reach one page.

Commit fb9a307d11 ("bpf: Allow CGROUP_SKB eBPF program to

type to use ld_abs/ind instructions. However, at this point,
we cannot use them, since offsets relative to SKF_LL_OFF will
end up pointing skb_mac_header(skb) out of bounds since in the
egress path it is not yet set at that point in time, but only
after __dev_queue_xmit() did a general reset on the mac header.
bpf_internal_load_pointer_neg_helper() will then end up reading
data from a wrong offset.
BPF_PROG_TYPE_CGROUP_SKB programs can use bpf_skb_load_bytes()
already to access packet data, which is also more flexible than
the insns carried over from cBPF.

stmmac_tso_allocator can fail to set the Last Descriptor bit

This happens when the buffer of the last descriptor ends

When the IP eventually reaches the next last descriptor,
which actually has the bit set, the DMA will hang.
When the DMA hangs, we get a tx timeout, however,
since stmmac does not do a complete reset of the IP
in stmmac_tx_timeout, we end up in a state with

This patch generates an unique ID for each BPF_PROG_LOAD-ed prog.
It is worth to note that each BPF_PROG_LOAD-ed prog will have
a different ID even they have the same bpf instructions.
The ID is generated by the existing idr_alloc_cyclic().
The ID is ranged from [1, INT_MAX). It is allocated in cyclic manner,
so an ID will get reused every 2 billion BPF_PROG_LOAD.
The bpf_prog_alloc_id() is done after bpf_prog_select_runtime()
because the jit process may have allocated a new prog. Hence,
we need to ensure the value of pointer 'prog' will not be changed
any more before storing the prog to the prog_idr.
After bpf_prog_select_runtime(), the prog is read-only. Hence,
the id is stored in 'struct bpf_prog_aux'.

For kernel datapath, this action does not make much sense. So with the

Merge tag 'media/v4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media fixes from Mauro Carvalho Chehab:
"Some bug fixes:
- Don't fail build if atomisp has warnings
- Some CEC Kconfig changes to allow it to be used by DRM without
media dependencies
- A race fix at RC initialization code
- A driver fix at rainshadow-cec
IMHO, the one that affects most people in this series is a build fix:
if you try to build the Kernel with W=1 or using gcc7 and
all[yes|mod]config, build will fail due to -Werror at atomisp
makefiles"
* tag 'media/v4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
[media] rc-core: race condition during ir_raw_event_register()
[media] cec: drop MEDIA_CEC_DEBUG
[media] cec: rename MEDIA_CEC_NOTIFIER to CEC_NOTIFIER
[media] cec: select CEC_CORE instead of depend on it
[media] rainshadow-cec: ensure exit_loop is intialized
[media] atomisp: don't treat warnings as errors
The check to see of err is set and the subsequent goto is extraneous
as the next statement is where the goto is jumping to. Remove this
redundant check and goto.

====================
Intel Wired LAN Driver Updates 2017-06-06
This series contains fixes to i40e and i40evf only.
Mauro S. M. Rodrigues fixes a flood in the kernel log which was introduced
in a previous commit because of a mistaken substitution of __I40E_VSI_DOWN
instead of __I40E_DOWN when testing the state of the PF.
Björn Töpel fixes an issue introduced in a previous commit where the
offset was incorrect and could lead to data corruption for architectures
using PAGE_SIZE larger than 8191. Fixed the issue by updating the
page_offset correctly using the proper setting for truesize.
