2005-07-07[PATCH] dvb: Twinhan DST: frontend fixesManu Abraham
o Make the inversion setting specific, ie, only for the 200103A DVB-S This should not be flagged on other cards. o Make the frequency setting card specific o Make the bandwidth setting generic such that it supports more DVB-T cards o Set QAM size for DVB-C cards that do not autodetect QAM size o Fix a bug that caused the polarization not to be set. Set polarization for cards that do not autodetect polarization o Fix a bogus frontend signal lock, that caused a tuning delay as well. o Make the Symbolrate setting card specific Signed-off-by: Manu Abraham <manu@kromtek.com> Signed-off-by: Johannes Stezenbach <js@linuxtv.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-07-07[PATCH] dvb: flexcop: woraround irq stop problemPatrick Boettcher
The flexcop chip often stops generating interrupts after some hours of operation. Apparently this can be fixed by resetting register block 0x300 at each channel change (this is not detailed in the flexcop data books). This patch also restructures DMA handling and adds a bit of debug code for the irq problem in case it still happens for someone.

2005-07-07[PATCH] IB uverbs: core API extensionsRoland Dreier
First of a series of patches which add support for direct userspace access to InfiniBand hardware -- so-called "userspace verbs." I believe these patches are ready to merge, but a final review would be useful. These patches should incorporate all of the feedback from the discussion when I posted an earlier version back in April (see http://lkml.org/lkml/2005/4/4/267 for the start of the thread). In particular, memory pinned for use by userspace is accounted for in current->mm->vm_locked and requests to pin memory are checked against RLIMIT_MEMLOCK. This patch: Modify the ib_verbs.h header file with changes required for InfiniBand userspace verbs support. We add a few structures to keep track of userspace context, and extend the driver API so that low-level drivers know when they're creating resources that will be used from userspace.

2005-07-07[PATCH] mostly_read data sectionChristoph Lameter
Add a new section called ".data.read_mostly" for data items that are read frequently and rarely written to like cpumaps etc. If these maps are placed in the .data section then these frequenly read items may end up in cachelines with data is is frequently updated. In that case all processors in an SMP system must needlessly reload the cachelines again and again containing elements of those frequently used variables. The ability to share these cachelines will allow each cpu in an SMP system to keep local copies of those shared cachelines thereby optimizing performance.

2005-07-07[PATCH] tty output lossage fixRoman Zippel
The patch fixes a few corner cases around tty line editing with very long input lines: - n_tty_receive_char(): don't simply drop eol characters, otherwise canon_data isn't increased and the reader isn't woken up. - n_tty_receive_room(): If there is no newline pending and the edit buffer is full, allow only a single character to be written (until eol is found and the line is flushed), so characters from the next line aren't dropped. - write_chan(): if an incomplete line was written, continue writing until write() returns 0, otherwise it might not write the eol character to flush the line and the writer goes to sleep without ever being woken up. BTW the core problem is that part of this should be handled in the receive_buf path, but for this it has to return the number of written characters, as the amount of written characters may not be the same as the amount of characters going into the write buffer, so the receive_room() usage in pty_write() is not really reliable. Alan said: The problem looks valid. The behaviour of 'traditional unix' appears to be the following If you exceed the line limit then beep and drop the character Always allow EOL to complete a canonical line input Always do signal/control processing if enabled Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
