2.6.12-rc1-pa6 use work queue in LED/LCD driver instead of tasklet. Main advantage is it allows use of msleep() in the led_LCD_driver to "atomically" perform two MMIO writes (CMD, then DATA). Lead to nice cleanup of the main led_work_func() and led_LCD_driver(). Kudos to David for being persistent. From: David Pye <dmp@davidmpye.dyndns.org> Signed-off-by:

Optimize ext2_find_next_zero_bit. Gives about 25% perf improvement with a rsync test with ext3. Signed-off-by:
Randolph Chung <tausq@parisc-linux.org> fix ext3 performance - ext2_find_next_zero() was culprit. Kudos to jejb for pointing out the the possibility that ext2_test_bit and ext2_find_next_zero() may in fact not be enumerating bits in the bitmap because of endianess. Took sparc64 implementation and adapted it to our tree. I suspect the real problem is ffz() wants an unsigned long and was getting garbage in the top half of the unsigned int. Not confirmed but that's what I suspect. Signed-off-by:
James Bottomley <jejb@parisc-linux.org> Fixup bitops.h to use volatile for *_bit() ops Based on this email thread: http://marc.theaimsgroup.com/?t=108826637900003 In a nutshell: *_bit() want use of volatile. __*_bit() are "relaxed" and don't use spinlock or volatile. other minor changes: o replaces hweight64() macro with alias to generic_hweight64() (Joel Soete) o cleanup ext2* macros so (a) it's obvious what the XOR magic is about and (b) one version that works for both 32/64-bit. o replace 2 uses of CONFIG_64BIT with __LP64__. bitops.h used both. I think header files that might go to user space should use something userspace will know about (__LP64__). Signed-off-by:

2.6.12-rc4-pa3 : first pass at making sure use of RFI conforms to PA 2.0 arch pages F-4 and F-5, PA 1.1 Arch page 3-19 and 3-20. The discussion revolves around all the rules for clearing PSW Q-bit. The hard part is meeting all the rules for "relied upon translation". .align directive is used to guarantee the critical sequence ends more than 8 instructions (32 bytes) from the end of page.

Fix card-mode Dino crashes on 725 (and probably other Snake) systems. Dino was coming up in fatal mode after a warm reboot. Resetting Dino brings it out of fatal mode, so do that if the status register indicates we're in fatal mode. Since this was never observed on any later systems, I presume firmware does this for us on those. Signed-off-by:

When I originally moved exit_itimers into __exit_signal, that was the only place where we could reliably know it was the last thread in the group dying, without races. Since then we've gotten the signal_struct.live counter, and do_exit can reliably do group-wide cleanup work. This patch moves the call to do_exit, where it's made without locks. This avoids the deadlock issues that the old __exit_signal code's comment talks about, and the one that Oleg found recently with process CPU timers. [ This replaces e03d13e9, which is why it was just reverted. ] Signed-off-by:

AMD recently discovered that on some hardware, there is a race condition possible when a C-state change request goes onto the bus at the same time as a P-state change request. Both requests happen, but the southbridge hardware only acknowledges the C-state change. The PowerNow! driver is then stuck in a loop, waiting for the P-state change acknowledgement. The driver eventually times out, but can no longer perform P-state changes. It turns out the solution is to resend the P-state change, which the southbridge will acknowledge normally. Thanks to Johannes Winkelmann for reporting this and testing the fix. Signed-off-by:

This fixes a stupid typo bug in the iSeries hash table code. When we place a hash PTE in the secondary bucket, instead of setting the SECONDARY flag bit, as we should, we (redundantly) set the VALID flag. This was introduced with the patch abolishing bitfields from the hash table code. Mea culpa, oops. It hasn't been noticed until now because in practice we don't hit the secondary bucket terribly often. Signed-off-by:

While working on 64K pages, I found this little buglet in our update_mmu_cache() implementation. The code calls __hash_page() passing it an "access" parameter (the type of access that triggers the hash) containing the bits _PAGE_RW and _PAGE_USER of the linux PTE. The latter is useless in this case and the former is wrong. In fact, if we have a writeable PTE and we pass _PAGE_RW to hash_page(), it will set _PAGE_DIRTY (since we track dirty that way, by hash faulting !dirty) which is not what we want. In fact, the correct fix is to always pass 0. That means that only read-only or already dirty read write PTEs will be preloaded. The (hopefully rare) case of a non dirty read write PTE can't be preloaded this way, it will have to fault in hash_page on the actual access. Signed-off-by:

This fixes a typo in the div128_by_32 function used in the timekeeping calculations on ppc64. If you look at the code it's quite obvious that we need (rb + c) rather than (rb + b). The "b" is clearly just a typo. Signed-off-by:

It is legitimate to call tcp_fragment with len == skb->len since that is done for FIN packets and the FIN flag counts as one byte. So we should only check for the len > skb->len case. Signed-off-by:

Turns out the problem has nothing to do with use-after-free or double-free. It's just that we're not clearing the CB area and DCCP unlike TCP uses a CB format that's incompatible with IP. Signed-off-by:

icmp_send doesn't use skb->sk at all so even if skb->sk has already been freed it can't cause crash there (it would've crashed somewhere else first, e.g., ip_queue_xmit). I found a double-free on an skb that could explain this though. dccp_sendmsg and dccp_write_xmit are a little confused as to what should free the packet when something goes wrong. Sometimes they both go for the ball and end up in each other's way. This patch makes dccp_write_xmit always free the packet no matter what. This makes sense since dccp_transmit_skb which in turn comes from the fact that ip_queue_xmit always frees the packet. Signed-off-by:

In fact we already have that flag, it's called skb->sk. So here is patch to test that instead of skb_cloned(). Signed-off-by:
