This patch (as1037) makes a small update to the earlier as1035 patch. The minimum-length computation shouldn't be done in usb_stor_access_xfer_buf(), since that routine can be called multiple times for a single transfer. It should be done in usb_stor_set_xfer_buf() instead, which gets called only once. The way it is now isn't really _wrong_, but it isn't really _right_ either. Moving the statement will be an improvement. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This patch removes the buffering of the status register. USB core behavior has changed a bit and this buffering was not refreshed at the right time. The core got buffered old value of HCRHPORT and it did not detect any devices on boot.

USB: ehci: Fixes completion for multi-qtd URB the short read case When use of urb->status in the EHCI driver was reworked last August (commit 14c04c0f), a bug was inserted in the handling of early completion for bulk transactions that need more than one qTD (e.g. more than 20KB in one URB). This patch resolves that problem by ensuring that the early completion status is preserved until the URB is handed back to its submitter, instead of resetting it after each qTD.

Hence we revert them and try again in v2.6.26.

Construct Xen guest e820 map with a hole between 640K-1M. It's pure luck that Xen kernels have gotten away with it in the past. The patch below seems like the right thing to do.

This bug got introduced by the recent i387 merge: commit 44210111 Author: Roland McGrath <roland@redhat.com> Date: Wed Jan 30 13:31:50 2008 +0100 x86: x86 i387 user_regset Current usage of unlazy_fpu() in ptrace specific routines is wrong. unlazy_fpu() will not init fpu if the task never used math. So the ptrace calls can expose the parent tasks FPU data in some cases. Replace it with the init_fpu() which will init the math state, if the task never used math before.

This changes the "freezer" code used by suspend/hibernate in its treatment of tasks in TASK_STOPPED (job control stop) and TASK_TRACED (ptrace) states. As I understand it, the intent of the "freezer" is to hold all tasks from doing anything significant. For this purpose, TASK_STOPPED and TASK_TRACED are "frozen enough". It's possible the tasks might resume from ptrace calls (if the tracer were unfrozen) or from signals (including ones that could come via timer interrupts, etc). But this doesn't matter as long as they quickly block again while "freezing" is in effect. Some minor adjustments to the signal.c code make sure that try_to_freeze() very shortly follows all wakeups from both kinds of stop. This lets the freezer code safely leave stopped tasks unmolested. Changing this fixes the longstanding bug of seeing after resuming from suspend/hibernate your shell report "[1] Stopped" and the like for all your jobs stopped by ^Z et al, as if you had freshly fg'd and ^Z'd them. It also removes from the freezer the arcane special case treatment for ptrace'd tasks, which relied on intimate knowledge of ptrace internals.

KVM tries to run as much as possible with the guest msrs loaded instead of host msrs, since switching msrs is very expensive. It also tries to minimize the number of msrs switched according to the guest mode; for example, MSR_LSTAR is needed only by long mode guests. This optimization is done by setup_msrs(). However, we must not change which msrs are switched while we are running with guest msr state: - switch to guest msr state - call setup_msrs(), removing some msrs from the list - switch to host msr state, leaving a few guest msrs loaded An easy way to trigger this is to kexec an x86_64 linux guest. Early during setup, the guest will switch EFER to not include SCE. KVM will stop saving MSR_LSTAR, and on the next msr switch it will leave the guest LSTAR loaded. The next host syscall will end up in a random location in the kernel. Fix by reloading the host msrs before changing the msr list. Signed-off-by: Avi Kivity <avi@qumranet.com>

For improved concurrency, the guest walk is performed concurrently with other vcpus. This means that we need to revalidate the guest ptes once we have write-protected the guest page tables, at which point they can no longer be modified. The current code attempts to avoid this check if the shadow page table is not new, on the assumption that if it has existed before, the guest could not have modified the pte without the shadow lock. However the assumption is incorrect, as the racing vcpu could have modified the pte, then instantiated the shadow page, before our vcpu regains control: vcpu0 vcpu1 fault walk pte modify pte fault in same pagetable instantiate shadow page lookup shadow page conclude it is old instantiate spte based on stale guest pte We could do something clever with generation counters, but a test run by Marcelo suggests this is unnecessary and we can just do the revalidation unconditionally. The pte will be in the processor cache and the check can be quite fast. Signed-off-by: Avi Kivity <avi@qumranet.com>
