2009-01-12fbdev: c2p - CleanupsGeert Uytterhoeven
- Improve comments and naming - Convert macros to static inline functions - Remove superfluous `break' after `return' - Make sure we get a build-time error (undefined reference to 'c2p_unsupported') in case of future misuse - Replace `unsigned long' by `u32' in comp(), as that's what all callers use - Use {get,put}_unaligned_be32() in store_planar{,_masked}() - Use void * for arbitrary pointers - Use a union to represent pixels/words, to avoid casts Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

2009-01-12fbdev: atafb - Fix line length handlingGeert Uytterhoeven
- Make sure par->next_line is always set (this was done for Falcon only), as all the text console drawing operations need a valid par->next_line, - Make sure fix->line_length is always set, as some userspace applications need it because they don't have fallback code for the case where it's zero.

2009-01-12rt2x00: Fix rt2500usb HW crypto: WEP 128 & AESIvo van Doorn
The TXD_W0_CIPHER field is a 1-bit field. It only acts as boolean value to indicate if the frame must be encrypted or not. The way rt2x00_set_field32() worked it would grab the least signifcant bit from txdesc->cipher and use that as value. Because of that WEP 64 and TKIP worked since they had odd-numbered values, while WEP 128 and AES were even numbers and didn't work. Correctly booleanize the txdecs->cipher value to allow the hardware to encrypt the outgoing data. After this we can enable HW crypto by default again.

Due to misunderstanding of the returned values allowed for the tx callback of mac80211, rtl8187 was using skb's that had been freed. This problem was triggered when the module was sujected to a rmmod/insmod cycle. After that was fixed, the modules would not work after the rmmod/insmod cycle until the USB device was reset.

This patch hopefully fixes a mac80211<->p54 interaction problem, which was described by Larry Finger (ref: http://marc.info/?l=linux-wireless&m=123009889327707 ) I guess the warning was triggered by pending frames in the receive queue, while we're doing a band change 5GHz.

2009-01-12ath9k: Revert fix to TX status reporting for retries and MCS indexJouni Malinen
This patch reverts "ath9k: Fix TX status reporting for retries and MCS index" because that change ended up breaking ath9k rate control. While the MCS index reporting to mac80211 was indeed fixed by the patch, it did not take into account that the ath9k rate control algorithm was updating private tables based on this index and the index comes through the rate control API call, i.e., based on mac80211 TX status call. In addition, it looks like the "fix" to remove +1 from TX status 'count' field was not correct based on ieee80211_tx_status() implementation that counts the total of count values, but starting from -1, not 0. The TX status reporting for frames using MCS needs to be fixed somehow, but it does not look like there is any easy fix for the ath9k rate control algorithm, so the best option now seems to be to revert the change and bring it back once the rate control code is cleaned up to handle this better.

2009-01-12rt2x00: Fix segementation faultIvo van Doorn
The queue_end() macro points to 1 position after the queue, which means that if we want to know if queue is at the end of the queue we should first increment the position and then check if it is a valid entry. This fixes a segmentation fault which only occurs when the device has enough endpoints to provide a dedicated endpoint for all TX queues (which likely won't happen for rt2500usb and rt73usb, but will happen for rt2800usb).

2009-01-12orinoco: take the driver lock in the rx taskletDavid Kilroy
Fix the warning reproduced below. We add to rx_list in interrupt context and remove elements in tasklet context. While removing elements we need to prevent the interrupt modifying the list. Note that "orinoco: Process bulk of receive interrupt in a tasklet" did not preserve locking semantics on what is now orinoco_rx. This patch reinstates the locking semantics and ensures it covers rx_list as well. This leads to additional cleanup required in free_orinocodev.

The commit introduces work_on_cpu() use into the cpufreq code, but that is subtly problematic from a lock hierarchy POV: the hotplug-cpu lock is an highlevel lock that is taken before lowlevel locks, and in this codepath we are called with the policy lock taken. Dieter did not have lockdep enabled so we dont have a nice stack trace proof for this, but using work_on_cpu() in such a lowlevel place certainly looks wrong, so we revert the patch. work_on_cpu() needs to be reworked to be more generally usable.

2009-01-12x86: avoid theoretical vmalloc fault loopAndi Kleen
Ajith Kumar noticed: I was going through the vmalloc fault handling for x86_64 and am unclear about the following lines in the vmalloc_fault() function. pgd = pgd_offset(current->mm ?: &init_mm, address); pgd_ref = pgd_offset_k(address); Here the intention is to get the pgd corresponding to the current process and sync it up with the pgd in init_mm(obtained from pgd_offset_k). However, for kernel threads current->mm is NULL and hence pgd = pgd_offset(init_mm, address) = pgd_ref which means the fault handler returns without setting the pgd entry in the MM structure in the context of which the kernel thread has faulted. This could lead to never-ending faults and busy looping of kernel threads like pdflush. So, shouldn't the pgd = pgd_offset(current->mm ?: &init_mm, address); be pgd = pgd_offset(current->active_mm ?: &init_mm, address); We can use active_mm unconditionally because it should be always set.

2009-01-12lockdep, mm: fix might_fault() annotationPeter Zijlstra
Some code (nfs/sunrpc) uses socket ops on kernel memory while holding the mmap_sem, this is safe because kernel memory doesn't get paged out, therefore we'll never actually fault, and the might_fault() annotations will generate false positives.

2009-01-12Revert "sched: improve preempt debugging"Ingo Molnar
This reverts commit 7317d7b87edb41a9135e30be1ec3f7ef817c53dd. This has been reported (and bisected) by Alexey Zaytsev and Kamalesh Babulal to produce annoying warnings during bootup on both x86 and powerpc. kernel_locked() is not a valid test in IRQ context (we update the BKL's ->lock_depth and the preempt count separately and non-atomicalyy), so we cannot put it into the generic preempt debugging checks which can run in IRQ contexts too.
