2008-01-30x86: assign IRQs to HPET timers, fixBalaji Rao
Looks like IRQ 31 is assigned to timer 3, even without the patch! I wonder who wrote the number 31. But the manual says that it is zero by default. I think we should check whether the timer has been allocated an IRQ before proceeding to assign one to it. Here is a patch that does this.

2008-01-30x86: assign IRQs to HPET timersBalaji Rao
The userspace API for the HPET (see Documentation/hpet.txt) did not work. The HPET_IE_ON ioctl was failing as there was no IRQ assigned to the timer device. This patch fixes it by allocating IRQs to timer blocks in the HPET. arch/x86/kernel/hpet.c | 13 +++++-------- drivers/char/hpet.c | 45 ++++++++++++++++++++++++++++++++++++++------- include/linux/hpet.h | 2 +- 3 files changed, 44 insertions(+), 16 deletions(-) Signed-off-by: Balaji Rao <balajirrao@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Cleaning out all the incorrect 'no change made' checks for termios settings showed up a problem with the PL2303. The hardware here seems to lose sync and bits if you tell it to make no changes. This shows up with a real world application. To fix this the driver check for meaningful hardware changes is restored but doing the tests correctly and as a tty layer function so it doesn't get duplicated wrongly everywhere if other drivers turn out to need it.

2007-12-23tty: fix logic change introduced by wait_event_interruptible_timeout()Cory T. Tusar
Commit 5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8 introduced a subtle logic change in tty_wait_until_sent(). The original version would only error out of the 'do { ... } while (timeout)' loop if signal_pending() evaluated to true; a timeout or break due to an empty buffer would fall out of the loop and into the tty->driver->wait_until_sent handling. The current implementation will error out on either a pending signal or an empty buffer, falling through to the tty->driver->wait_until_sent handling only on a timeout. The ->wait_until_sent() will not be reached if the buffer empties before timeout jiffies have elapsed. This behavior differs from that prior to commit 5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8. I turned this up while using a little serial download utility to bootstrap an ARM-based eval board. The util worked fine on 2.6.22.x, but consistently failed on 2.6.23.x. Once I'd determined that, I narrowed things down with git bisect, and found the above difference in logic in tty_wait_until_sent() by inspection. This change reverts the logic flow in tty_wait_until_sent() to match that prior to the aforementioned commit. Signed-off-by: Cory T.

The AMD CS5535/CS5536 GPIO has two alternate output modes: AUX-1 and AUX-2. When either AUX is enabled, the cs5535_gpio driver cannot control the output.

2007-11-14rtc: fall back to requesting only the ports we actually useBjorn Helgaas
Firmware like PNPBIOS or ACPI can report the address space consumed by the RTC. The actual space consumed may be less than the size (RTC_IO_EXTENT) assumed by the RTC driver. The PNP core doesn't request resources yet, but I'd like to make it do so. If/when it does, the RTC_IO_EXTENT request may fail, which prevents the RTC driver from loading. Since we only use the RTC index and data registers at RTC_PORT(0) and RTC_PORT(1), we can fall back to requesting just enough space for those. If the PNP core requests resources, this results in typical I/O port usage like this: 0070-0073 : 00:06 <-- PNP device 00:06 responds to 70-73 0070-0071 : rtc <-- RTC driver uses only 70-71 instead of the current: 0070-0077 : rtc <-- RTC_IO_EXTENT == 8 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-11-07[TTY]: Fix network driver interactions with TCGET/SET calls.Alan Cox
Dave Miller noted various cases where line disciplines for things like ppp go poking around in termios themselves in ways that broke with the new termios code. Rather than have them all learning about termios internals provide proper methods for this - tty_mode_ioctl() This handles all the terminal mode handling for speed/carrier etc and none of the methods are ldisc dependant so they can be called by any user - tty_perform_flush() This extracts the flush functionality and enables pppd the ppp layer to share it cleanly. The existing n_tty_ioctl code is refactored in this patch to provide the new functions and to call them itself appropriately. This patch has no (intended) behaviour changes and simply prepares for the other fixes. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-10-23Char: cyclades, fix potential NULL dereferenceJiri Slaby
ztxdone is jumped to even if tty is NULL and tty_wakeup placed after this label doesn't expect NULLed parameter, so this will cause an oops in some situations (why they scheduled a wakeup there before remove bottom half processing patch?). wakeup only in the case when we have non-null tty struct.
