Some work is needed in the tpm device driver to discover the TPM out of the device tree rather than based on set address on Power PPC. This patch exports a couple of functions for the parsing. Signed-off-by:

The access_ok_tt() macro is bogus, in that a read access is unconditionally considered valid. I couldn't find in SCM logs the introduction of this check, but I went back to 2.4.20-1um and the definition was the same. Possibly this was done to avoid problems with missing set_fs() calls, but there can't be any I think because they would fail with SKAS mode. TT-specific code is still to check. Also, this patch joins common code together, and makes the "address range wrapping" check happen for all cases, rather than for only some. This may, possibly, be reoptimized at some time, but the current code doesn't seem clever, just confused. * Important: I've also had to change references to access_ok_{tt,skas} back to access_ok - the kernel wasn't that happy otherwise.

Since the 4th param is unused, remove it altogether. Signed-off-by:

Paolo 'Blaisorblade' Giarrusso authored
We were using a long series of (stupid) wrappers which all call generic_console_write(). Since the wrappers only change the 4th param, which is unused by the called proc, remove them and call generic_console_write() directly. If needed at any time in the future to reintroduce this stuff, the member could be moved to a generic struct, to avoid this duplicated handling. Signed-off-by:

printk clears the host errno (I verified this in debugging and it's reasonable enough, given that it ends via a write call on some fd, especially since printk() goes on /dev/tty0 which is often the host stdout). So save errno earlier. There's no reason to change the printk calls to use -err rather than errno - the assignment can't clear errno. And in the first failure path, we used to return 0 too (and this time more clearly), which is totally wrong. 0 is a success fd, which is then registered and gives a "registering fd twice" warning. Finally, fix up some whitespace. Signed-off-by:

A few fixups - show the new submenu only for x86 subarchitecture (it does not make sense to show it for x86_64 users) and remove X86_CMPXCHG, which is now a duplicate of Kconfig.i386, even though Kconfig doesn't complain (we also miss the dependency on !M386 CPU). Signed-off-by:

The below warning was added in place of pte_mkyoung(); if (is_write) pte_mkdirty(); In fact, if the PTE is not marked young/dirty, our dirty/accessed bit emulation would cause the TLB permission not to be changed, and so we'd loop, and given we don't support preemption yet, we'd busy-hang here. However, I've seen this warning trigger without crashes during a loop of concurrent kernel builds, at random times (i.e. like a race condition), and I realized that two concurrent faults on the same page, one on read and one on write, can trigger it. The read fault gets serviced and the PTE gets marked writable but clean (it's possible on a shared-writable mapping), while the generic code sees the PTE was already installed and returns without action. In this case, we'll see another fault and service it normally. Signed-off-by:

Remove task_work structure, use the standard thread flags functions and use shifts in entry.S to test the thread flags. Add a few local labels to entry.S to allow gas to generate short jumps. Finally it changes a number of inline functions in thread_info.h to macros to delay the current_thread_info() usage, which requires on m68k a structure (task_struct) not yet defined at this point.

a) in smp_lock.h #include of sched.h and spinlock.h moved under #ifdef CONFIG_LOCK_KERNEL. b) interrupt.h now explicitly pulls sched.h (not via smp_lock.h from hardirq.h as it used to) c) in three more places we need changes to compensate for (a) - one place in arch/sparc needs string.h now, hardirq.h needs forward declaration of task_struct and preempt.h needs direct include of thread_info.h. d) thread_info-related helpers in sched.h and thread_info.h put under ifndef __HAVE_THREAD_FUNCTIONS. Obviously safe. Signed-off-by:

Fix http://bugzilla.kernel.org/show_bug.cgi?id=5546 The cpu_khz global is not initialized and remains 0 if you boot with clock=pit, even if the processor does have a TSC. This may have bad ramifications since the variable is used in various places scattered around the kernel, though I didn't check them all to see if they can tolerate cpu_khz = 0. You can observe the problem by doing "cat /proc/cpuinfo"; the cpu MHz line says 0.000. The fix is trivial; call init_cpu_khz() from init_pit(), just as it's called from the timers/timer_foo.c:init_foo() for other values of foo. Cc: john stultz <johnstul@us.ibm.com> Signed-off-by:

The MPC8349 PIBs system has a expansion board with 6 PCI slots. We needed to update the IDSEL interrupt mapping for it to work properly. However, only PCI1 is supported as the first revision of this expansion board doesn't function properly for PCI2. For the time being we have zero'd out the entries for the IDSELs related to PCI2. When a functioning expansion board exists we can fix the table. Signed-off-by:

Patch from Richard Purdie Add a driver for the extra GPIOs found on the Sharp SL-C1000 (Akita). These GPIOs are found on a Maxim MAX7310 I2C i/o expander chip. A generic GPIO driver for the MAX7310 was attempted but this mini driver is a much simpler and much more effective solution avoiding several issues and complexity the generic driver had (as discussed on LKML). The platform device is required so the device parent can be set correctly which ensures the device is one of the last to suspend and first to resume. Whilst the i2c suspend/resume calls can be influenced, nothing guarantees this is easlier/later than the subsystems the gpios are used on which are all independent of i2c (sound, irda, video/backlight etc.).
