the case where the target gets request that is so large that it cannot
execute it in one dma operation. So max_secotors or a segment limit may

This same bug has now been introduced twice: it was done earlier by

We must NOT try to queue up notify handlers to another thread than the
normal ACPI execution thread, because the notifications on some systems
seem to just keep on accumulating until we run out of memory and/or

Keeping events within the one deferred execution thread automatically

[PATCH] i386/x86_64: ACPI cpu_idle_wait() fix

The scheduler on Andreas Friedrich's hyperthreading system stopped
working properly: the scheduler would never move tasks to another CPU!
The lask known working kernel was 2.6.8.

After a couple of attempts to corner the bug, the following smoking gun
was found:

  BIOS reported wrong ACPI idfor the processor

   [<c0103a87>] kernel_thread_helper+0x7/0x10

a quick look at cpu_idle_wait() shows how broken that code is
on i386: it changes the init task's affinity map but never
restores it ...

and because all userspace tasks get forked by init, they all
inherited that single-CPU affinity mask. x86_64 cloned this
bug too.

this crash happened because it did not sanitize the dwarf2 data it
got, and got an unaligned stack pointer - which happily walked past
the process stack (and eventually reached the end of kernel memory
and pagefaulted there) due to this naive iteration condition:

        HANDLE_STACK (((long) stack & (THREAD_SIZE-1)) != 0);

note that i386 is alot more conservative when it comes to trusting
stack pointers:

  static inline int valid_stack_ptr(struct thread_info *tinfo, void *p)
  {
         return  p > (void *)tinfo &&
                 p < (void *)tinfo + THREAD_SIZE - 3;
  }

but the x86_64 code did not take this bit of i386 code.

The fix is to align the stack pointer.

USB: correct keymapping on Powerbook built-in USB ISO keyboards

similar to the version in adbhid_input_register(): The '<>' key and the
'^°' key on a german keyboard is swapped.  Provide correct keys to
userland, external USB keyboards will not work correctly when the
'badmap'/'goodmap' workarounds from xkeyboard-config are used.

It is expected that distributions drop the badmap/goodmap part from
keycodes/macintosh in the xkeyboard-config package.

This is probably 2.6.18.x material, if major distros settle on 2.6.18.

USB: OHCI: fix root-hub resume bug

When a suspended OHCI controller sees a port's status change, it sets
both the Root-Hub-Status-Change and the Resume-Detect bits in the
Interrupt Status register.  Processing both these bits, the driver
tries to resume the root hub twice!

This patch (as807) fixes the bug by ignoring RD if RHSC is set.  It
also prints a slightly more informative log message when a
remote-wakeup event occurs.
