Add blacklisting capability to serial_pci to avoid misdetection of serial ports

The serial_pci driver tries to guess serial ports on unknown devices based
on the PCI class (modem or serial).  On certain softmodems (AC'97 modems)
this can lead to the recognition of non-existing serial ports.

This patch adds a blacklist of PCI IDs that are to be ignored by the driver.

Serial 8250: handle saving the clear-on-read bits from the LSR and MSR

Reading the LSR clears the break, parity, frame error, and overrun bits in
the 8250 chip, but these are not being saved in all places that read the
LSR.  Same goes for the MSR delta bits.  Save the LSR bits off whenever the
lsr is read so they can be handled later in the receive routine.  Save the
MSR bits to be handled in the modem status routine.

Also, clear the stored bits and clear the interrupt registers before
enabling interrupts, to avoid handling old values of the stored bits in the
interrupt routines.

serial: don't optimise away baud rate changes when BOTHER is used

The uart_set_termios() function will bail out early without bothering to
touch the hardware, if it decides that nothing "relevant" has changed.
Unfortunately, its idea of "relevant" doesn't include c_[io]speed.  So if
the baud rate bits are BOTHER and you just change the speed, the change
gets optimised away.

This patch makes it ignore the old Bfoo bits in c_cflag and just check
whether c_ispeed and c_ospeed have changed.  Those integers are always set
appropriately for us by set_termios().

This occurs because the section to node id mapping is not being

Error opening lower file for lower_dentry [0xffff810233a6f150], lower_mnt [0xffff810235bb4c80], and flags [0x8000]

  # mount -t ecryptfs /root/crypt /mnt/crypt

[S390] kprobes: fix instruction length calculation

Placing a kprobe on "bc" instruction (s390/s390x) can cause an oops.
The instruction length is encoded into the first two bits of the s390
instruction. Kprobe is incorrectly computing the instruction length.
The instruction length is used for determining what type of "fix-up" is
needed for conditional branch instruction. The problem can bee seen by
placing a kprobe on a "bc" instruction that will not branch. The

CCQ=96 was issued regardless whether buffer states for at least one
buffer were extracted or not.
This caused FCP devices to hang when running under z/VM and having

In order to fix this qdio return code processing of EQBS instruction
after CCQ=96 is changed that buffers are returned and if no buffers
where extracted the instruction is repeated at once.

Cornelia Huck [Wed, 22 Aug 2007 11:51:37 +0000]
[S390] cio: change confusing message in cmf.

cmf currently prints a message that more than 4096 channels are not
allowed in basic mode - however, this can only be enforced if cmf was
a module (which is no longer possible). It makes much more sense to
not check the specified number of channels and just print a message if
the block for basic mode could not be allocated (which may happen for
any number of specified channels).

12 years agodio: zero struct dio with kzalloc instead of manually
Zach Brown [Tue, 21 Aug 2007 00:12:01 +0000]
dio: zero struct dio with kzalloc instead of manually

This patch uses kzalloc to zero all of struct dio rather than manually
trying to track which fields we rely on being zero.  It passed aio+dio
stress testing and some bug regression testing on ext3.

This patch was introduced by Linus in the conversation that lead up to
Badari's minimal fix to manually zero .map_bh.b_state in commit:

  6a648fa72161d1f6468dabd96c5d3c0db04f598a

It makes the code a bit smaller.  Maybe a couple fewer cachelines to
load, if we're lucky:

   text    data     bss     dec     hex filename
3285925  568506 1304616 5159047  4eb887 vmlinux
3285797  568506 1304616 5158919  4eb807 vmlinux.patched

I was unable to measure a stable difference in the number of cpu cycles
spent in blockdev_direct_IO() when pushing aio+dio 256K reads at
~340MB/s.

So the resulting intent of the patch isn't a performance gain but to
avoid exposing ourselves to the risk of finding another field like
.map_bh.b_state where we rely on zeroing but don't enforce it in the
code.

This ensures that a bootconsole is unregistered if it is not replaced.
The current implementation spews garbage out the bootconsole in this case,
since the bootconsole structure is normally in the init section, and is
freed, but still used.

V4L/DVB (6027): Get rid of an ill-behaved msleep in i2c write

Configuring the OLPC camera requires something over 150 register
writes.  Unfortunately, querying the CAFE i2c controller too
soon after a write causes the hardware to flake.  The problem had
been "solved" with an msleep() call, but, between the number of
registers and how msleep() behaves, that resulted in a 3-second
delay on camera initialization.  Instead, we hand-code a wait for
the completion interrupt which avoids reading the status registers.

12 years agox86: properly initialize temp insn buffer for paravirt patching
Chris Wright [Sat, 18 Aug 2007 21:31:41 +0000]
x86: properly initialize temp insn buffer for paravirt patching

With commit ab144f5ec64c42218a555ec1dbde6b60cf2982d6 the patching code
now collects the complete new instruction stream into a temp buffer
before finally patching in the new insns.  In some cases the paravirt
patchers will choose to leave the patch site unpatched (length mismatch,
clobbers mismatch, etc).

This causes the new patching code to copy an uninitialized temp buffer,
i.e.  garbage, to the callsite.  Simply make sure to always initialize
the buffer with the original instruction stream.  A better fix is to
audit all the patchers and return proper length so that apply_paravirt()
can skip copies when we leave the patch site untouched.

x86_64: Fail dma_alloc_coherent on dma less devices

This should fix an oops with PCMCIA PATA devices

http://bugzilla.kernel.org/show_bug.cgi?id=8424

This is not a full fix for the problem, but probably
still the right thing to do.

[ I'm almost certain it's *not* the right thing to do, but it avoids an
  oops, and I want comments from others on what the right thing would
  actually be..  I suspect we should just remove the use of dma_mask
  entirely in this function, and just use coherent_dma_mask.  - Linus ]

12 years agofix random hang in forcedeth driver when using netconsole
Timo Jantunen [Tue, 14 Aug 2007 18:56:57 +0000]
fix random hang in forcedeth driver when using netconsole

If the forcedeth driver receives too much work in an interrupt, it
assumes it has a broken hardware with stuck IRQ.  It works around the
problem by disabling interrupts on the nic but makes a printk while
holding device spinlog - which isn't smart thing to do if you have
netconsole on the same nic.

This patch moves the printk's out of the spinlock protected area.

Without this patch the machine hangs hard.  With this patch everything
still works even when there is significant increase on CPU usage while
using the nic.

12 years agoi386: Fix a couple busy loops in mach_wakecpu.h:wait_for_init_deassert()
Satyam Sharma [Thu, 16 Aug 2007 00:39:25 +0000]
i386: Fix a couple busy loops in mach_wakecpu.h:wait_for_init_deassert()

Use cpu_relax() in the busy loops, as atomic_read() doesn't automatically
imply volatility for i386 and x86_64. x86_64 doesn't have this issue because
it open-codes the while loop in smpboot.c:smp_callin() itself that already
uses cpu_relax().

For i386, however, smpboot.c:smp_callin() calls wait_for_init_deassert()
which is buggy for mach-default and mach-es7000 cases.

[ I test-built a kernel -- smp_callin() itself got inlined in its only
  callsite, smpboot.c:start_secondary() -- and the relevant piece of
  code disassembles to the following:

0xc1019704 <start_secondary+12>:        mov    0xc144c4c8,%eax
0xc1019709 <start_secondary+17>:        test   %eax,%eax
0xc101970b <start_secondary+19>:        je     0xc1019709 <start_secondary+17>

  init_deasserted (at 0xc144c4c8) gets fetched into %eax only once and
  then we loop over the test of the stale value in the register only,
  so these look like real bugs to me. With the fix below, this becomes:

0xc1019706 <start_secondary+14>:        pause
0xc1019708 <start_secondary+16>:        cmpl   $0x0,0xc144c4c8
0xc101970f <start_secondary+23>:        je     0xc1019706 <start_secondary+14>

  which looks nice and healthy. ]

Thanks to Heiko Carstens for noticing this.
