2009-01-30memcg: get/put parents at create/freeDaisuke Nishimura1-1/+22
The lifetime of struct cgroup and struct mem_cgroup is different and mem_cgroup has its own reference count for handling references from swap_cgroup. This causes strange problem that the parent mem_cgroup dies while child mem_cgroup alive, and this problem causes a bug in case of use_hierarchy==1 because res_counter_uncharge climbs up the tree. This patch is for avoiding it by getting the parent at create, and putting it at freeing.

2009-01-30Fix OOPS in mmap_region() when merging adjacent VM_LOCKED file segmentsLinus Torvalds1-20/+6
As of commit ba470de43188cdbff795b5da43a1474523c6c2fb ("map: handle mlocked pages during map, remap, unmap") we now use the 'vma' variable at the end of mmap_region() to handle the page-in of newly mapped mlocked pages. However, if we merged adjacent vma's together, the vma we're using may be stale. We historically consciously avoided using it after the merge operation, but that got overlooked when redoing the locked page handling. This commit simplifies mmap_region() by doing any vma merges early, avoiding the issue entirely, and 'vma' will always be valid. As pointed out by Hugh Dickins, this depends on any drivers that change the page offset of flags to have set one of the VM_SPECIAL bits (so that they cannot trigger the early merge logic), but that's true in general.

2009-01-30gianfar: Fix Wake-on-LAN supportAnton Vorontsov1-0/+2
commit 0f0ca340e57bd7446855fefd07a64249acf81223 ("phy: power management support") caused a regression in the gianfar driver. Now phylib turns off PHY power during suspend, and thus WOL doesn't work anymore. This patch workarounds the issue by enabling wakeup in the MDIO device, i.e. just restores the old behaviour for the gianfar driver. Note that this way all PHYs on a given MDIO bus won't be turned off during suspend, which isn't good from the power saving point of view. A proper, per netdevice wakeup management support will need a bit reworked phylib suspend/resume logic. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.

2009-01-30wimax: fix build issue when debugfs is disabledInaky Perez-Gonzalez4-25/+29
As reported by Toralf Förster and Randy Dunlap. - http://linuxwimax.org/pipermail/wimax/2009-January/000460.html - http://lkml.org/lkml/2009/1/29/279 The definitions needed for the wimax stack and i2400m driver debug infrastructure was, by mistake, compiled depending on CONFIG_DEBUG_FS (by them being placed in the debugfs.c files); thus the build broke in 2.6.29-rc3 when debugging was enabled (CONFIG_WIMAX_DEBUG) and DEBUG_FS was disabled. These definitions are always needed if debug is enabled at compile time (independently of DEBUG_FS being or not enabled), so moving them to a file that is always compiled fixes the issue.

It oopsd for me in skb_seq_read. addr2line said it was linux-2.6/net/core/skbuff.c:2228, which is this line: while (st->frag_idx < skb_shinfo(st->cur_skb)->nr_frags) { I added some printks in there and it looks like we hit this: } else if (st->root_skb == st->cur_skb && skb_shinfo(st->root_skb)->frag_list) { st->cur_skb = skb_shinfo(st->root_skb)->frag_list; st->frag_idx = 0; goto next_skb; } Actually I did some testing and added a few printks and found that the st->cur_skb->data was 0 and hence the ptr used by iscsi_tcp was null. This caused the kernel panic. if (abs_offset < block_limit) { - *data = st->cur_skb->data + abs_offset; + *data = st->cur_skb->data + (abs_offset - st->stepped_offset); I enabled the debug_tcp and with a few printks found that the code did not go to the next_skb label and could find that the sequence being followed was this - It hit this if condition - if (st->cur_skb->next) { st->cur_skb = st->cur_skb->next; st->frag_idx = 0; goto next_skb; And so, now the st pointer is shifted to the next skb whereas actually it should have hit the second else if first since the data is in the frag_list. else if (st->root_skb == st->cur_skb && skb_shinfo(st->root_skb)->frag_list) { st->cur_skb = skb_shinfo(st->root_skb)->frag_list; goto next_skb; } Reversing the two conditions the attached patch fixes the issue for me on top of Herbert's patches.

2009-01-30powerpc/5200: Bugfix for PCI mapping of memory and IMMRGrant Likely1-14/+10
This patch ensures that memory gets properly mapped into the PCI address space. Without this patch, the memory window BAR is left at whatever value happened to be loaded into the BAR when Linux was booted. Without this patch, memory could end up getting mapped at any of the 1G address boundaries instead of at '0' where Linux expects it. Similarly, this patch also ensures that the internally memory mapped registers (IMMR) are mapped to the correct PCI address range. Without this patch, PCI appears to work correctly until a PCI device is inserted which DMAs into memory.

According to https://bugs.launchpad.net/bugs/294391 - 3rd generation iPods need the "fix capacity" workaround after all (apparently they crash after the last sector was accessed), - 2nd generation iPods need the "128 kB maximum request size" workaround. Alas both iPod generations feature the same model ID in the config ROM, hence we can only define a shared quirks list entry for them. Luckily the fix capacity workaround did not show a negative effect in Jarod's tests with 2nd gen. iPod. A side note: Apple computers in target mode (or at least an x86 Mac mini) don't have firmware_version and model_id, hence none of the iPod quirks list entries is active for them.

2009-01-29ARM: OMAP: Mask interrupts when disabling interrupts, v2김규원1-0/+1
By Ingo Molnar, interrupts are not masked by default. (refer to 76d2160147f43f982dfe881404cfde9fd0a9da21) But if interrupts are not masked, the processor can wake up while in Suspend-to-RAM state by an external interrupt. For example, if an OMAP3 board is connected to Host PC by USB and entered to Suspend-to-RAM state, it wake up automatically by M_IRQ_92. The disable_irq() function can't disable the interrupt in H/W level, So I modified arch/arm/mach-omap2/irq.c Signed-off-by: Kim Kyuwon <chammoru@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-01-29ARM: OMAP: gptimer min_delta_ns correctedAaro Koskinen1-1/+2
When 32 kHz timer is used the min_delta_ns should be initialized so that it reflects the timer programming cost. A write to the timer device will be usually posted, but it takes roughly 3 cycles before it is effective. If the timer is reprogrammed before that, the CPU will stall until the previous write completes. This was pointed out by Richard Woodruff. Since the lower bound for min_delta_ns is 1000, the change is visible only with tick rates less than 3 MHz. Also note that the old value is incorrect for 32 kHz also due to a rounding error, and it can cause the timer queue to hang (due to clockevent code trying to program the timer with zero ticks).

2009-01-29ARM: OMAP: DMA: Fix uninitialized channel flagsJarkko Nikula1-0/+1
This has similar symptoms than 66c23551b1b774e2be3c7bdf91c0ebf2c7a3519e where just omap_request_dma, omap_dma_link_lch and omap_dma_unlink_lch can cause incorrect dump_stack(). Here it can happen if channel has been used before and the channel flags variable holds old status.

2009-01-29ARM: OMAP: Fix race in OMAP2/3 DMA IRQ handlingJuha Yrjola1-2/+2
CSR must be cleared before invoking the callback. If the callback function starts a new, fast DMA transfer on the same channel, the completion status might lost if CSR is cleared after the callback invocation.
