saa7134: fix thread shutdown handling

This patch changes the test for the thread pid from >= 0 to > 0.

When the saa8134 driver initialization fails after a certain point, it goes
through the complete shutdown process for the driver.  Part of shutting it
down includes tearing down the thread for tv audio.

The test for tearing down the thread tests for >= 0.  Since the dev
structure is kzalloc'd, the test will always be true if we haven't tried to
start the thread yet.  We end up waiting on pid 0 to complete, which will
never happen, so we lock up.

Fix Kconfig dependency problems wrt boolean menuconfigs

If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result.  If BAZ=m, then BAR can be set
y, which allows FOO=y.  It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ.  In effect, the bool
promotes the tristate from m to y.

This ends up causing a problem with several menuconfigs that look like:

menuconfig BAR
bool
depends on BAZ [tristate]
if BAR
config FOO
tristate
endif

The solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ.  This is how it would work if a menu

mm: kill validate_anon_vma to avoid mapcount BUG

validate_anon_vma gave a useful check on the integrity of the anon_vma list
when Andrea was developing obj rmap; but it was not enabled in SLES9
itself, nor in mainline, until Nick changed commented-out RMAP_DEBUG to
configurable CONFIG_DEBUG_VM in 2.6.17.  Now Petr Vandrovec reports that
its BUG_ON(mapcount > 100000) can easily crash a CONFIG_DEBUG_VM=y system.

That limit was just an arbitrary number to protect against an infinite
loop.  We could raise it to something enormous (depending on sizeof struct
vma and size of memory?); but I rather think validate_anon_vma has outlived
its usefulness, and is better just removed - which gives a magnificent
performance boost to anything like Petr's test program ;)

Of course, a very long anon_vma list is bad news for preemption latency,
and I believe there has been one recent report of such: let's not forget
that, but validate_anon_vma only makes it worse not better.

PNP SMCf010 quirk: auto-config device if BIOS left it broken

Some HP firmware leaves the SMCf010 IRDA device incompletely configured, or
reports the wrong resources in _CRS.  As a workaround, when we find such a
device, try to auto-configure the device.

This ignores the _CRS data, picks a config from _PRS, and runs _SRS to
configure the device.  This makes smsc-ircc2 work correctly with PNP
resources (with no preconfiguration!) on all the machines I tested.

I think Windows does something like this by default for all devices,
so we should consider doing the same thing in Linux.

This patch addresses part of the 2.6.22 regression:
    "no irda0 interface (2.6.21 was OK), smsc does not find chip"
It fixes smsc-ircc2 PNP device detection on HP nc6000, nc6220, nw8000,
nw8240, and possibly other machines.

x86_64 irq: use mask/unmask and proper locking in fixup_irqs()

Force irq migration path during cpu offline, is not using proper locks and
irq_chip mask/unmask routines.  This will result in some races(especially
the device generating the interrupt can see some inconsistent state,
resulting in issues like stuck irq,..).

Appended patch fixes the issue by taking proper lock and encapsulating
irq_chip set_affinity() with a mask() before and an unmask() after.

This fixes a MSI irq stuck issue reported by Darrick Wong.

There are several more general bugs in this area(irq migration in the
process context). For example,

 1. Possibility of missing edge triggered irq.
 2. Reliable method of migrating level triggered irq in the process context.

We plan to look and close these in the near future.

Eric says:
In addition even with the fix from Suresh there is still at least one
nasty hardware race in fixup_irqs().   However we exercise that code
path rarely enough that we are unlikely to hit it in the real world,
and that race seems to have existed since the code was merged.  And a
fix for that is not coming soon as it is an open investigation area
if we can fix irq migration to work outside of irq context or if
we have to rework the requirements imposed by the generic cpu hotplug
and layer on fixup_irqs().  So this may come up again.

[POWERPC] Fix subtle FP state corruption bug in signal return on SMP

This fixes a bug which can cause corruption of the floating-point state
on return from a signal handler.  If we have a signal handler that has
used the floating-point registers, and it happens to context-switch to
another task while copying the interrupted floating-point state from the
user stack into the thread struct (e.g. because of a page fault, or
because it gets preempted), the context switch code will think that the
FP registers contain valid FP state that needs to be copied into the
thread_struct, and will thus overwrite the values that the signal return
code has put into the thread_struct.

This can occur because we clear the MSR bits that indicate the presence
of valid FP state after copying the state into the thread_struct.  To fix
this we just move the clearing of the MSR bits to before the copy.  A
similar potential problem also occurs with the Altivec state, and this
fixes that in the same way.

x86_64: fix misplaced `continue' in mce.c

Background:
  When a userspace application wants to know about machine check events, it
  opens /dev/mcelog and does a read(). Usually, we found that this interface
  works well, but in some cases, when the system was taking large numbers of
  machine check exceptions, the read() would hang. The system would output a
  soft-lockup warning, and the daemon reading from /dev/mcelog would suck up
  as much of a single CPU as it could spinning in system space.

Description:
  This patch fixes this bug. In particular, there was a "continue" inside a
  timeout loop that presumably was intended to break out of the outer loop,
  but instead caused the inner loop to continue. This patch also makes the
  condition for the break-out a little more evident by changing a
  !time_before to a time_after_eq.

Result:
  The read() no longer hangs in this test case.

Testing:
  On my system, I could replicate the bug with the following command:
    # for i in `seq 15000`; do ./inject_sbe.sh; done
  where inject_sbe.sh contains commands to inject a single-bit error into the
  next memory write transaction.

alpha: fix alignment problem in csum_ipv6_magic()

Hopefully this fixes http://bugzilla.kernel.org/show_bug.cgi?id=8635

The struct in6_addr passed to csum_ipv6_magic() is 4 byte aligned, so we
can't use the regular 64-bit loads.  Since the cost of handling of 4 byte

any src/dst [mis]alignment.

17 years agoconsole UTF-8 fixes (fix)
Egmont Koblinger [Sun, 24 Jun 2007 00:16:27 +0000 (17:16 -0700)]
console UTF-8 fixes (fix)

Recently my console UTF-8 patch went mainline.  Here is an additional patch
that fixes two nasty issues and improves a third one, namely:

1. My patch changed the behavior if a glyph is not found in the Unicode
   mapping table. Previously for Unicode values less than 256 or 512 the
   kernel tried to display the glyph from that position of the glyph table,
   which could lead to a different accented letter being displayed. I
   removed this fallback possibility and changed it to display the
   replacement symbol.

   As Behdad pointed out, some fonts (e.g. sun12x22 from the kbd package)
   lack Unicode mapping information, hence all you get is lots of question
   marks. Though theoretically it's actually a user-space bug (the font
   should be fixed), Behdad and I both believe that it'd be good to work
   around in the kernel by re-introducing the fallback solution for ASCII
   characters only. This sounds a quite reasonable decision, since all fonts
   ship the ASCII characters in the first 128 positions. This way users
   won't be surprised by lots of question marks just because s/he issued a
   not-so-perfectly parameterized setfont command. As this fallback is only
   re-introduced for code points below 128, you still won't see an accented
   letter replaced by another, but at least you'll always get the English
   letters right.

2. My patch introduced "question mark with inverted color attributes" as a
   last resort fallback glyph. Though it perfectly works on VGA console, on
   framebuffer you may end up with question marks that are highlighed but
   shouldn't be, and normal characters that are accidentally highlighed.
   This is caused by missing FLUSHes when changing the color attribute.

3. I've updated the table of double-width character based on Markus's
   updated version. Only ten new code poings (one interval) is added.
