perf parse: Fix event parser error for hybrid systems

This bug happened on hybrid systems when both cpu_core and cpu_atom
have the same event name such as "UOPS_RETIRED.MS" while their event
terms are different, then during perf stat, the event for cpu_atom
will parse fail and then no output for cpu_atom.

UOPS_RETIRED.MS -> cpu_core/period=0x1e8483,umask=0x4,event=0xc2,frontend=0x8/
UOPS_RETIRED.MS -> cpu_atom/period=0x1e8483,umask=0x1,event=0xc2/

It is because event terms in the "head" of parse_events_multi_pmu_add
will be changed to event terms for cpu_core after parsing UOPS_RETIRED.MS
for cpu_core, then when parsing the same event for cpu_atom, it still
uses the event terms for cpu_core, but event terms for cpu_atom are
different with cpu_core, the event parses for cpu_atom will fail. This
patch fixes it, the event terms should be parsed from the original
event.

This patch can work for the hybrid systems that have the same event
in more than 2 PMUs. It also can work in non-hybrid systems.

x86/sgx: Free backing memory after faulting the enclave page

There is a limited amount of SGX memory (EPC) on each system.  When that
memory is used up, SGX has its own swapping mechanism which is similar
in concept but totally separate from the core mm/* code.  Instead of
swapping to disk, SGX swaps from EPC to normal RAM.  That normal RAM
comes from a shared memory pseudo-file and can itself be swapped by the
core mm code.  There is a hierarchy like this:

EPC <-> shmem <-> disk

After data is swapped back in from shmem to EPC, the shmem backing
storage needs to be freed.  Currently, the backing shmem is not freed.
This effectively wastes the shmem while the enclave is running.  The
memory is recovered when the enclave is destroyed and the backing
storage freed.

Sort this out by freeing memory with shmem_truncate_range(), as soon as
a page is faulted back to the EPC.  In addition, free the memory for
PCMD pages as soon as all PCMD's in a page have been marked as unused
by zeroing its contents.

cachefiles: Fix volume coherency attribute

A network filesystem may set coherency data on a volume cookie, and if
given, cachefiles will store this in an xattr on the directory in the
cache corresponding to the volume.

The function that sets the xattr just stores the contents of the volume
coherency buffer directly into the xattr, with nothing added; the
checking function, on the other hand, has a cut'n'paste error whereby it
tries to interpret the xattr contents as would be the xattr on an
ordinary file (using the cachefiles_xattr struct).  This results in a
failure to match the coherency data because the buffer ends up being
shifted by 18 bytes.

Fix this by defining a structure specifically for the volume xattr and
making both the setting and checking functions use it.

Since the volume coherency doesn't work if used, take the opportunity to
insert a reserved field for future use, set it to 0 and check that it is
0.  Log mismatch through the appropriate tracepoint.

Note that this only affects cifs; 9p, afs, ceph and nfs don't use the
volume coherency data at the moment.

afs: Fix potential thrashing in afs writeback

In afs_writepages_region(), if the dirty page we find is undergoing
writeback or write to cache, but the sync_mode is WB_SYNC_NONE, we go

watch_queue: Fix lack of barrier/sync/lock between post and read

There's nothing to synchronise post_one_notification() versus
pipe_read().  Whilst posting is done under pipe->rd_wait.lock, the
reader only takes pipe->mutex which cannot bar notification posting as
that may need to be made from contexts that cannot sleep.

Fix this by setting pipe->head with a barrier in post_one_notification()
and reading pipe->head with a barrier in pipe_read().

If that's not sufficient, the rd_wait.lock will need to be taken,
possibly in a ->confirm() op so that it only applies to notifications.
The lock would, however, have to be dropped before copy_page_to_iter()
is invoked.

watch_queue: Fix to always request a pow-of-2 pipe ring size

The pipe ring size must always be a power of 2 as the head and tail
pointers are masked off by AND'ing with the size of the ring - 1.
watch_queue_set_size(), however, lets you specify any number of notes
between 1 and 511.  This number is passed through to pipe_resize_ring()
without checking/forcing its alignment.

Fix this by rounding the number of slots required up to the nearest
power of two.  The request is meant to guarantee that at least that many
notifications can be generated before the queue is full, so rounding
down isn't an option, but, alternatively, it may be better to give an
error if we aren't allowed to allocate that much ring space.

watch_queue, pipe: Free watchqueue state after clearing pipe ring

case of a notification message, this is watch_queue_pipe_buf_release()

watch_queue: Fix filter limit check

In watch_queue_set_filter(), there are a couple of places where we check
that the filter type value does not exceed what the type_filter bitmap
can hold.  One place calculates the number of bits by:

   if (tf[i].type >= sizeof(wfilter->type_filter) * 8)

which is fine, but the second does:

   if (tf[i].type >= sizeof(wfilter->type_filter) * BITS_PER_LONG)

which is not.  This can lead to a couple of out-of-bounds writes due to
a too-large type:

 (1) __set_bit() on wfilter->type_filter
 (2) Writing more elements in wfilter->filters[] than we allocated.

Fix this by just using the proper WATCH_TYPE__NR instead, which is the
number of types we actually know about.

riscv: Fix auipc+jalr relocation range checks

RISC-V can do PC-relative jumps with a 32bit range using the following
two instructions:

auipc t0, imm20 ; t0 = PC + imm20 * 2^12
jalr ra, t0, imm12 ; ra = PC + 4, PC = t0 + imm12

Crucially both the 20bit immediate imm20 and the 12bit immediate imm12
are treated as two's-complement signed values. For this reason the
immediates are usually calculated like this:

imm20 = (offset + 0x800) >> 12
imm12 = offset & 0xfff

..where offset is the signed offset from the auipc instruction. When
the 11th bit of offset is 0 the addition of 0x800 doesn't change the top
20 bits and imm12 considered positive. When the 11th bit is 1 the carry
of the addition by 0x800 means imm20 is one higher, but since imm12 is
then considered negative the two's complement representation means it
all cancels out nicely.

However, this addition by 0x800 (2^11) means an offset greater than or
equal to 2^31 - 2^11 would overflow so imm20 is considered negative and
result in a backwards jump. Similarly the lower range of offset is also
moved down by 2^11 and hence the true 32bit range is

[-2^31 - 2^11, 2^31 - 2^11)

so ice_plug_aux_dev() is called from ice_service_task() context.
This unfortunately opens a race window that can result in dead-lock
when interface has left LAG and immediately enters LAG again.

Reproducer:
```
#!/bin/sh

ip link add lag0 type bond mode 1 miimon 100
ip link set lag0

for n in {1..10}; do

1. Command 'ip link ... set nomaster' causes that ice_plug_aux_dev()
   is called from ice_service_task() context, aux device is created
   and associated device->lock is taken.
2. Command 'ip link ... set master...' calls ice's notifier under
   RTNL lock and that notifier calls ice_unplug_aux_dev(). That
   function tries to take aux device->lock but this is already taken
   by ice_plug_aux_dev() in step 1
3. Later ice_plug_aux_dev() tries to take RTNL lock but this is already
   taken in step 2
4. Dead-lock

The patch fixes this issue by following changes:
- Bit ICE_FLAG_PLUG_AUX_DEV is kept to be set during ice_plug_aux_dev()
  call in ice_service_task()
- The bit is checked in ice_clear_rdma_cap() and only if it is not set
  then ice_unplug_aux_dev() is called. If it is set (in other words
  plugging of aux device was requested and ice_plug_aux_dev() is
  potentially running) then the function only clears the bit
- Once ice_plug_aux_dev() call (in ice_service_task) is finished
  the bit ICE_FLAG_PLUG_AUX_DEV is cleared but it is also checked
  whether it was already cleared by ice_clear_rdma_cap(). If so then
  aux device is unplugged.

net: phy: meson-gxl: improve link-up behavior

Sometimes the link comes up but no data flows. This patch fixes
this behavior. It's not clear what's the root cause of the issue.

According to the tests one other link-up issue remains.
In very rare cases the link isn't even reported as up.

net: bcmgenet: Don't claim WOL when its not available

Some of the bcmgenet platforms don't correctly support WOL, yet
ethtool returns:

"Supports Wake-on: gsf"

which is false.

Ideally if there isn't a wol_irq, or there is something else that
keeps the device from being able to wakeup it should display:

"Supports Wake-on: d"

This patch checks whether the device can wakup, before using the
hard-coded supported flags. This corrects the ethtool reporting, as
well as the WOL configuration because ethtool verifies that the mode
is supported before attempting it.

net: arc_emac: Fix use after free in arc_mdio_probe()

If bus->state is equal to MDIOBUS_ALLOCATED, mdiobus_free(bus) will free
the "bus". But bus->name is still used in the next line, which will lead
to a use after free.

We can fix it by putting the name in a local variable and make the
bus->name point to the rodata section "name",then use the name in the
error message without referring to bus to avoid the uaf.
