Anton Vorontsov 619baba195 gianfar: Revive the driver for eTSEC devices (disable timestamping)
Since commit cc772ab7cd ("gianfar: Add
hardware RX timestamping support"), the driver no longer works on
at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more
boards as well).

That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit:

  Timestamp incoming packets as padding bytes. PAL field is set
  to 8 if the PAL field is programmed to less than 8. Must be set
  to zero if TMR_CTRL[TE]=0.

I see that the commit above sets this bit, but it doesn't handle
TMR_CTRL. Manfred probably had this bit set by the firmware for
his boards. But obviously this isn't true for all boards in the
wild.

Also, I recall that Freescale BSPs were explicitly disabling the
timestamping because of a performance drop.

For now, the best way to deal with this is just disable the
timestamping, and later we can discuss proper device tree bindings
and implement enabling this feature via some property.

David Howells a7f5378e24 FRV: Reinstate null behaviour for the GDB remote protocol 'p' command
Reinstate the null behaviour that the in-kernel gdbstub had for the GDB
remote protocol 'p' command (retrieve a single register value) prior to
commit 7ca8b9c0da ("frv: extend gdbstub to support more features of
gdb").

Before that, the 'p' command just returned an empty reply, which causes
gdb to then go and use the 'g' command.  However, since that commit, the
'p' command returns an error string, which causes gdb to abort its
connection to the target.

Not all gdb versions are affected, some use try 'g' first, and if that
works, don't bother with 'p', and so don't see the error.

If cr0.wp=0, we have to allow the guest kernel access to a page with pte.w=0.
We do that by setting spte.w=1, since the host cr0.wp must remain set so the

user access otherwise we mistakenly allow the user to write the page.

Always invalidate spte and flush TLBs when changing page size, to make

Currently the only case where this occurs is when a non-leaf spte pointer is

logging is disabled on a memslot, for example.

dma_direct_map_sg() sets sg->dma_length, however microblaze doesn't
set NEED_SG_DMA_LENGTH so scatterlist strcutres doesn't include
dma_length.

sg->dma_length is always equal to sg->length on microblaze. So we
don't need to set set dma_length, that is, microblaze can simply use
sg->length.

Dave Chinner d87815cb20 writeback: limit write_cache_pages integrity scanning to current EOF
sync can currently take a really long time if a concurrent writer is
extending a file. The problem is that the dirty pages on the address
space grow in the same direction as write_cache_pages scans, so if
the writer keeps ahead of writeback, the writeback will not
terminate until the writer stops adding dirty pages.

For a data integrity sync, we only need to write the pages dirty at
the time we start the writeback, so we can stop scanning once we get
to the page that was at the end of the file at the time the scan
started.

This will prevent operations like copying a large file preventing
sync from completing as it will not write back pages that were
dirtied after the sync was started. This does not impact the
existing integrity guarantees, as any dirty page (old or new)
within the EOF range at the start of the scan will still be
captured.

This patch will not prevent sync from blocking on large writes into
holes. That requires more complex intervention while this patch only
addresses the common append-case of this sync holdoff.

Dave Chinner 0b5649278e writeback: pay attention to wbc->nr_to_write in write_cache_pages
If a filesystem writes more than one page in ->writepage, write_cache_pages
fails to notice this and continues to attempt writeback when wbc->nr_to_write
has gone negative - this trace was captured from XFS:

    wbc_writeback_start: towrt=1024
    wbc_writepage: towrt=1024
    wbc_writepage: towrt=0
    wbc_writepage: towrt=-1
    wbc_writepage: towrt=-5
    wbc_writepage: towrt=-21
    wbc_writepage: towrt=-85

This has adverse effects on filesystem writeback behaviour. write_cache_pages()
needs to terminate after a certain number of pages are written, not after a
certain number of calls to ->writepage are made.  This is a regression
introduced by 17bc6c30cf ("vfs: Add
no_nrwrite_index_update writeback control flag"), but cannot be reverted
directly due to subsequent bug fixes that have gone in on top of it.

Oleg Nesterov b9b76dfaac tracing: Fix null pointer deref with SEND_SIG_FORCED
BUG: unable to handle kernel NULL pointer dereference at
	0000000000000006
IP: [<ffffffff8107bd37>] ftrace_raw_event_signal_generate+0x87/0x140

TP_STORE_SIGINFO() forgets about SEND_SIG_FORCED, fix.

We should probably export is_si_special() and change TP_STORE_SIGINFO()
to use it in the longer term.

Arnd Bergmann af0d5cb908 hp_sdc_rtc: fix broken ioctl conversion
Commit 55929332c9 "drivers: Push down BKL into various drivers"
introduced a regression in hp_sdc_rtc, caused by a missing
change of the .unlocked_ioctl pointer to the newly introduced
function.

Fixes:

	drivers/input/misc/hp_sdc_rtc.c:681: warning: initialization from
	incompatible pointer type
	drivers/input/misc/hp_sdc_rtc.c:665: warning:
	‘hp_sdc_rtc_unlocked_ioctl’ defined but not used

Khem Raj 9a40ac8615 ARM: 6164/1: Add kto and kfrom to input operands list.
When functions incoming parameters are not in input operands list gcc
4.5 does not load the parameters into registers before calling this
function but the inline assembly assumes valid addresses inside this
function. This breaks the code because r0 and r1 are invalid when
execution enters v4wb_copy_user_page ()

Also the constant needs to be used as third input operand so account
for that as well.

Tested on qemu arm.

Johannes Berg b054b747a6 mac80211: fix deauth before assoc
When we receive a deauthentication frame before
having successfully associated, we neither print
a message nor abort assocation. The former makes
it hard to debug, while the latter later causes
a warning in cfg80211 when, as will typically be
the case, association timed out.

This warning was reported by many, e.g. in
https://bugzilla.kernel.org/show_bug.cgi?id=15981,
but I couldn't initially pinpoint it. I verified
the fix by hacking hostapd to send a deauth frame
instead of an association response.

Anfei 5e27fb78df ARM: 6166/1: Proper prefetch abort handling on pre-ARMv6
Instruction faults on pre-ARMv6 CPUs are interpreted as
a 'translation fault', but do_translation_fault doesn't
handle well if user mode trying to run instruction above
TASK_SIZE, and result in the infinite retry of that
instruction.

Nicolas Pitre 17ebba1fe4 ARM: 6165/1: trap overflows on highmem pages from kmap_atomic when debugging
When CONFIG_DEBUG_HIGHMEM is used, the fixmap entry used for a highmem page
by kmap_atomic() is always cleared by kunmap_atomic().  This helps find
bad usages such as dereferences after the unmap, or overflow into the
adjacent fixmap areas.

But this debugging aid is completely bypassed when a kmap for the same
page already exists as the kmap is reused instead.  ON VIVT systems we
have no choice but to reuse that kmap due to cache coherency issues,
but on non VIVT systems we should always force the fixmap usage when
debugging is active.
