2007-11-13[PKT_SCHED]: Check subqueue status before calling hard_start_xmitPeter P Waskiewicz Jr
The only qdiscs that check subqueue state before dequeue'ing are PRIO and RR. The other qdiscs, including the default pfifo_fast qdisc, will allow traffic bound for subqueue 0 through to hard_start_xmit. The check for netif_queue_stopped() is done above in pkt_sched.h, so it is unnecessary for qdisc_restart(). However, if the underlying driver is multiqueue capable, and only sets queue states on subqueues, this will allow packets to enter the driver when it's currently unable to process packets, resulting in expensive requeues and driver entries. This patch re-adds the check for the subqueue status before calling hard_start_xmit, so we can try and avoid the driver entry when the queues are stopped.

2007-11-13Revert "ext2/ext3/ext4: add block bitmap validation"Linus Torvalds
This reverts commit 7c9e69faa28027913ee059c285a5ea8382e24b5d, fixing up conflicts in fs/ext4/balloc.c manually. The cost of doing the bitmap validation on each lookup - even when the bitmap is cached - is absolutely prohibitive. We could, and probably should, do it only when adding the bitmap to the buffer cache. However, right now we are better off just reverting it. Peter Zijlstra measured the cost of this extra validation as a 85% decrease in cached iozone, and while I had a patch that took it down to just 17% by not being _quite_ so stupid in the validation, it was still a big slowdown that could have been avoided by just doing it right.

The patch "KVM: fix !SMP build error" change the way smp_call_function() actually uses the passed in function names on non-SMP builds. So previously it was never caught that the function passed in was never actually defined. This causes a build error on ppc64_defconfig + CONFIG_SMP=n: arch/powerpc/mm/tlb_64.c: In function 'pgtable_free_now': arch/powerpc/mm/tlb_64.c:71: error: 'pte_free_smp_sync' undeclared (first use in this function) arch/powerpc/mm/tlb_64.c:71: error: (Each undeclared identifier is reported only once arch/powerpc/mm/tlb_64.c:71: error: for each function it appears in.)

2007-11-13[POWERPC] Avoid unpaired stwcx. on some processorsBecky Bruce
The context switch code in the kernel issues a dummy stwcx. to clear the reservation, as recommended by the architecture. However, some processors can have issues if this stwcx to address A occurs while the reservation is already held to a different address B. To avoid this problem, the dummy stwcx. needs to be paired with a dummy lwarx to the same address. This adds the dummy lwarx, and creates a cpu feature bit to indicate which cpus are affected. Tested on mpc8641_hpcn_defconfig in arch/powerpc; build tested in arch/ppc. Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-11-12[TG3]: 5784 / 5764 GPHY power down fixMatt Carlson
5784 and 5764 devices fail to link / pass traffic after one load / unload cycle. This happens because of a hardware bug in the new CPMU. During normal operation, the MAC depends on the PHY clock being available. When the PHY is powered down, the clock the MAC depends on is disabled. The fix is to switch the MAC clock to an alternate source before powering down the PHY, and to restore the MAC clock to the PHY source upon device resume.

2007-11-12[TG3]: Fix 5761 PXEboot crashMatt Carlson
When 5761 devices boot the machine using PXEboot, PXE leaves the device active when it terminates. The tg3 driver has code to detect this condition and resets the device during initialization. On 5761 devices, device resets involve sending a driver state update message to the APE on the 5761. However, during this initialization stage, communications to the APE registers have not yet been set up. The driver then dereferences a NULL pointer and crashes the machine. The fix is to move the APE register access setup earlier in the initialization code to cover this condition.

2007-11-12[SUNGEM]: Fix suspend regression due to NAPI changes.Johannes Berg
Commit bea3348e (the NAPI changes) made sungem unconditionally enable NAPI when resuming and unconditionally disable when suspending, this, however, makes napi_disable() hang when suspending when the interface was taken down before suspend because taking the interface down also disables NAPI. This patch makes touching the napi struct in suspend/resume code paths depend on having the interface up, thereby fixing the hang on suspend. The patch also moves the napi_disable() in gem_close() under the lock so that the NAPI state is always modified atomically together with the "opened" variable.

This works right most of the time, but is broken when a sigwait (rt_sigtimedwait) is in progress.

2007-11-12nfsd4: recheck for secure ports in fh_verifyJ. Bruce Fields
As with commit 7fc90ec93a5eb71f4b08403baf5ba7176b3ec6b1 ("knfsd: nfsd: call nfsd_setuser() on fh_compose(), fix nfsd4 permissions problem") this is a case where we need to redo a security check in fh_verify() even though the filehandle already has an associated dentry--if the filehandle was created by fh_compose() in an earlier operation of the nfsv4 compound, then we may not have done these checks yet. Without this fix it is possible, for example, to traverse from an export without the secure ports requirement to one with it in a single compound, and bypass the secure port check on the new export. While we're here, fix up some minor style problems and change a printk() to a dprintk(), to make it harder for random unprivileged users to spam the logs. Signed-off-by: J.
