2012-06-29powerpc: Fix BPF_JIT code to link with multiple TOCsMichael Ellerman1-0/+2
If the kernel is big enough (eg. allyesconfig), the linker may need to switch TOCs when calling from the BPF JIT code out to the external helpers (skb_copy_bits() & bpf_internal_load_pointer_neg_helper()). In order to do that we need to leave space after the bl for the linker to insert a reload of our TOC pointer.

In commit 7a87982420e5e126bfefeb42232d1fd92052794e we added a wrapper for the WDIOC_GETSTATUS ioctl call. The code results however in a different behaviour: it returns an error if the driver doesn't support the status operation. This is not according to the API that says that when we don't support the status operation, that we just should return a 0 value. Only when the device isn't there anymore, we should return an error.

As the lpc_ich driver now creates a platform device, auto-loading can easily be done by having a respective module alias in place.

2012-06-27PM / ACPI: Fix suspend/resume regression caused by cpuidle cleanup.Deepthi Dharwar1-2/+30
Commit e978aa7d7d57d04eb5f88a7507c4fb98577def77 ( cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state) was breaking suspend on laptops, as reported in the below link - https://lkml.org/lkml/2011/11/11/164 This was fixed in commit 3439a8da16bcad6b0982ece938c9f8299bb53584 (ACPI / cpuidle: Remove acpi_idle_suspend (to fix suspend regression) by removing acpi_idle_suspend flag. - https://lkml.org/lkml/2011/11/14/74 But this did fix did not work on all systems as Suspend/resume regression was reported on Lenovo S10-3 recently by Dave. - https://lkml.org/lkml/2012/5/27/115 It looked like with commit e978aa7d broke suspend and with commit 3439a8da resume was not working with acpi_idle driver. This patch fixes the regression that caused this issue in the first place. acpi_idle_suspend flag is essential on some x86 systems to prevent the cpus from going to deeper C-states when suspend is triggered ( commit b04e7bdb984 ) So reverting the commit 3439a8da is essential. By default, irqs are disabled in cpu_idle arch specific call and re-enabled in idle state return path . During suspend, the acpi_idle_suspend flag is set, which prevents the cpus from going to deeper idle states, it is essential to enabling the irqs in this return path too. To address the suspend issue, we were not re-enabling the interrupts while returning from acpi_idle_enter_bm() routine if acpi_idle_suspend flag is set. and this caused suspend failure. In addition to the above, to improve the readability of the code, return of -ENIVAL is replaced with -EBUSY in acpi_idle_suspend return path. Implying that the system is currently busy when suspend is in progress, which prevents the cpus from entering deeper C-states.

2012-06-26bridge: Assign rtnl_link_ops to bridge devices created via ioctl (v2)stephen hemminger3-1/+3
This ensures that bridges created with brctl(8) or ioctl(2) directly also carry IFLA_LINKINFO when dumped over netlink. This also allows to create a bridge with ioctl(2) and delete it with RTM_DELLINK.

2012-06-26vhost: use USER_DS in vhost_worker threadJens Freimann1-0/+3
On some architectures address spaces are set up in a way that this is not necessary to work properly but on some others (like s390) it is. Make sure we operate on the user address space to allow copy_xxx_user() from the vhost_worker() thread by setting it explicitly before calling use_mm() and revert it after unuse_mm().

2012-06-26ixgbe: Do not pad FCoE frames as this can cause issues with FCoE DDPAlexander Duyck3-7/+13
FCoE target mode was experiencing issues due to the fact that we were sending up data frames that were padded to 60 bytes after the DDP logic had already stripped the frame down to 52 or 56 depending on the use of VLANs. This was resulting in the FCoE DDP logic having issues since it thought the frame still had data in it due to the padding. To resolve this, adding code so that we do not pad FCoE frames prior to handling them to the stack.

2012-06-26Revert "mmc: omap_hsmmc: Enable Auto CMD12"Ming Lei1-12/+3
This patch reverts the commit dba3c29ea4a1d5d544. After bisecting, this commit dba3c29 is found to ruin micro-SD card data (writing incorrect file, or fs is corrupt after several times mount) on the beagle-xm revB, and reverting the commit will fix the problem. Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about the Auto CMD12 Enable bit. - SDIO does not support this feature. - SD card only. Looks it is not suitable to always enable Auto CMD12 in host controller driver. Considered that the commit is not mature enough, so ask to revert it first.
