MIPS: LD/SD o32 macro GAS fix update

I am about to commit:

http://sourceware.org/ml/binutils/2010-10/msg00033.html

that fixes a problem with the LD/SD macro currently implemented by GAS for
the o32 ABI in an inconsistent way.  This is best illustrated with a
simple program, which I'm copying here from the message above for easier
reference:

$ cat ld.s
ld $5,32767($4)
ld $5,32768($4)

This gets assebled into the following output:

$ mips-linux-as -32 -mips3 -o ld.o ld.s
$ mips-linux-objdump -d ld.o

ld.o:     file format elf32-tradbigmips

Disassembly of section .text:

00000000 <.text>:
   0: dc857fff  ld a1,32767(a0)
   4: 3c010001  lui at,0x1
   8: 00810821  addu at,a0,at
   c: 8c258000  lw a1,-32768(at)
  10: 8c268004  lw a2,-32764(at)
...

Oops!

 The GAS fix makes the macro behave in a consistent way and pairs of LW/SW
instructions to be output as appropriate regardless of the size of the
offset associated with the address used.  The machine instruction is still
available, but to reach it macros have to be disabled first.  This has a
side effect of requiring the use of a machine-addressable memory operand.

 As some platforms require 64-bit operations for accesses to some I/O
registers LD/SD instructions are used in a couple of places in Linux
regardless of the ABI selected.  Here's a fix for some pieces of code
affected I've been able to track down.  The fix should be backwards
compatible with all supported binutils releases in existence and can be
used as a reference for any other places or off-tree code.  The use of the
"R" constraint guarantees a machine-addressable operand.

install_special_mapping skips security_file_mmap check.

The install_special_mapping routine (used, for example, to setup the

attacker to bypass the mmap_min_addr security restriction by limiting
the available pages for special mappings.

bprm_mm_init() also skips the check, and although I don't think this can

ARM: 6533/1: Thumb-2: Make CONFIG_THUMB2_KERNEL depend on !CPU_V6

This makes sense, because Thumb-2 code can't execute on plain
ARMv6 processors.

This will avoid accidentally configuring a broken kernel where the
config otherwise would allow multiple architecture versions to
coexist in the same kernel.

Not adding !CPU_V5 etc., because the chance of anyone trying to
put v5 and v7 in the same kernel is low, and I'm not aware of
any mach which can do this.  These could be added later if it
matters.

Note that the rules may need to be refined if support for the
ARM1156J(F)-S processor is later added to the kernel, since this
processor supports the rare ARMv6T2 extensions, which add support

ext4: Turn off multiple page-io submission by default

Jon Nelson has found a test case which causes postgresql to fail with
the error:

psql:t.sql:4: ERROR: invalid page header in block 38269 of relation base/16384/16581

Under memory pressure, it looks like part of a file can end up getting
replaced by zero's.  Until we can figure out the cause, we'll roll
back the change and use block_write_full_page() instead of
ext4_bio_write_page().  The new, more efficient writing function can
be used via the mount option mblk_io_submit, so we can test and fix
the new page I/O code.

To reproduce the problem, install postgres 8.4 or 9.0, and pin enough
memory such that the system just at the end of triggering writeback
before running the following sql script:

begin;
create temporary table foo as select x as a, ARRAY[x] as b FROM
generate_series(1, 10000000 ) AS x;
create index foo_a_idx on foo (a);
create index foo_b_idx on foo USING GIN (b);
rollback;

If the temporary table is created on a hard drive partition which is
encrypted using dm_crypt, then under memory pressure, approximately
30-40% of the time, pgsql will issue the above failure.

This patch should fix this problem, and the problem will come back if
the file system is mounted with the mblk_io_submit mount option.

13 years agoworkqueue: It is likely that WORKER_NOT_RUNNING is true

workqueue: It is likely that WORKER_NOT_RUNNING is true

Running the annotate branch profiler on three boxes, including my
main box that runs firefox, evolution, xchat, and is part of the distcc farm,
showed this with the likelys in the workqueue code:

 correct incorrect  %        Function                  File              Line
 ------- ---------  -        --------                  ----              ----
      96   996253  99 wq_worker_sleeping             workqueue.c          703
      96   996247  99 wq_worker_waking_up            workqueue.c          677

The likely()s in this case were assuming that WORKER_NOT_RUNNING will
most likely be false. But this is not the case. The reason is
(and shown by adding trace_printks and testing it) that most of the time
WORKER_PREP is set.

In worker_thread() we have:

worker_clr_flags(worker, WORKER_PREP);

[ do work stuff ]

worker_set_flags(worker, WORKER_PREP, false);

(that 'false' means not to wake up an idle worker)

The wq_worker_sleeping() is called from schedule when a worker thread
is putting itself to sleep. Which happens most of the time outside
of that [ do work stuff ].

The wq_worker_waking_up is called by the wakeup worker code, which
is also callod outside that [ do work stuff ].

Thus, the likely and unlikely used by those two functions are actually
backwards.

Remove the annotation and let gcc figure it out.

Btrfs: prevent RAID level downgrades when space is low

The extent allocator has code that allows us to fill
allocations from any available block group, even if it doesn't
match the raid level we've requested.

This was put in because adding a new drive to a filesystem
made with the default mkfs options actually upgrades the metadata from
single spindle dup to full RAID1.

But, the code also allows us to allocate from a raid0 chunk when we
really want a raid1 or raid10 chunk.  This can cause big trouble because
mkfs creates a small (4MB) raid0 chunk for data and metadata which then
goes unused for raid1/raid10 installs.

The allocator will happily wander in and allocate from that chunk when
things get tight, which is not correct.

The fix here is to make sure that we provide duplication when the
caller has asked for it.  It does all the dups to be any raid level,
which preserves the dup->raid1 upgrade abilities.

Btrfs: account for missing devices in RAID allocation profiles

When we mount in RAID degraded mode without adding a new device to
replace the failed one, we can end up using the wrong RAID flags for
allocations.

This results in strange combinations of block groups (raid1 in a raid10
filesystem) and corruptions when we try to allocate blocks from single
spindle chunks on drives that are actually missing.

The first device has two small 4MB chunks in it that mkfs creates and
these are usually unused in a raid1 or raid10 setup.  But, in -o degraded,
the allocator will fall back to these because the mask of desired raid groups
isn't correct.

The fix here is to count the missing devices as we build up the list
of devices in the system.  This count is used when picking the
raid level to make sure we continue using the same levels that were
in place before we lost a drive.
