While making some other changes to ti_usb_3410_5052, I noticed that the changes made to move the firmware loading to a separate function are broken (in ti_download_firmware(), status is set to -ENOMEM and never changed). This means the driver will never initialize the device properly. It looks like status was supposed to get the result of ti_do_download().

2008-09-23USB: fix EHCI periodic transfersDavid Brownell
As noted by Stefan Neis <Stefan.Neis@kobil.com>, we had a recent regression with EHCI periodic transfers, in some (seemingly not all that common) cases. The root cause was that the schedule activation was only loosely coupled to the addition or removal of transfers, so two different execution contexts could both think they had to deactivate (or conversely activate) the schedule. So this fix tightens that coupling, managing it more like a refcount. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-09-23USB: fix hcd interrupt disablingGeoff Levand
Commit de85422b94ddb23c021126815ea49414047c13dc, 'USB: fix interrupt disabling for HCDs with shared interrupt handlers' changed usb_add_hcd() to strip IRQF_DISABLED from irqflags prior to calling request_irq() with the justification that such a removal was necessary for shared interrupts to work properly. Unfortunately, the change in that commit unconditionally removes the IRQF_DISABLED flag, causing problems on platforms that don't use a shared interrupt but require IRQF_DISABLED. This change adds a check for IRQF_SHARED prior to removing the IRQF_DISABLED flag. Fixes the PS3 system startup hang reported with recent Fedora and OpenSUSE kernels. Note that this problem is hidden when CONFIG_LOCKDEP=y (ps3_defconfig), as local_irq_enable_in_hardirq() is defined as a null statement for that config.

2008-09-23USB: ehci: fix some ehci hangs and crashesDavid Brownell
I noticed that the "Refactor "if (handshake()) state = HC_STATE_HALT" patch from earlier this year perpetuated a potential problem: it can mark the controller as halted when it's still running (but not acting as, perhaps wrongly, expected). That caused some hangs and crashes, rather than more polite failure modes of a truly halted controller. This patch forces a true halt, and emits a (previously missing) diagnostic.

Sometimes, particularly for USB devices with the last sector bug, requests get completed in chunks. There's a bug in this in that if one of the chunks gets an error, we complete that chunk with an error but never move on to the remaining ones, leading to the request hanging (because it's not fully completed).

2008-09-23atmel_serial: update the powersave handler to match serial coreAnti Sullin
This problem seems to be unnoticed so far: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b3b708fa2780cd2b5d8266a8f0c3a1cab364d4d2 has changed the serial core behavior to not to suspend the port if the device is enabled as a wakeup source. If the AT91 system goes to slow clock mode, the port should be suspended always and the clocks should be switched off. The patch attached updates the atmel_serial driver to match the changes in serial core. Also, the interrupts are disabled when the clock is disabled. If we disable the clock with interrupts enabled, an interrupt may get stuck. If this is the DBGU interrupt, this blocks the OR logic at system controller and thus all other sysc interrupts.

2008-09-23memcg: check under limit at shrink_usageDaisuke Nishimura
Current memory cgroup(both in mainline and -mm) doesn't account swap caches as memory(swap cache support is dropped temporarily now). So try_to_free_mem_cgroup_pages doesn't reflect the count of pages that have been moved to swap cache. But this makes mem_cgroup_shrink_usage fail easily if most of the pages are anon/shmem, and then shmem_getpage returns -ENOMEM and the process will be killed. This patch adds res_counter_check_under_limit to avoid these cases. BTW, even if swap cache support is enabled again, if a process is moved to another cgroup, which has been just made, between precharge and shrink_usage in shmem_getpage, shrink_usage may fail just because there is no pages to reclaim. So this change would make sense anyway.

2008-09-23sys_paccept: disable paccept() until API design is resolvedMichael Kerrisk
The reasons for disabling paccept() are as follows: * The API is more complex than needed. There is AFAICS no demonstrated use case that the sigset argument of this syscall serves that couldn't equally be served by the use of pselect/ppoll/epoll_pwait + traditional accept(). Roland seems to concur with this opinion (http://thread.gmane.org/gmane.linux.kernel/723953/focus=732255). I have (more than once) asked Ulrich to explain otherwise (http://thread.gmane.org/gmane.linux.kernel/723952/focus=731018), but he does not respond, so one is left to assume that he doesn't know of such a case. * The use of a sigset argument is not consistent with other I/O APIs that can block on a single file descriptor (e.g., read(), recv(), connect()). * The behavior of paccept() when interrupted by a signal is IMO strange: the kernel restarts the system call if SA_RESTART was set for the handler. I think that it should not do this -- that it should behave consistently with paccept()/ppoll()/epoll_pwait(), which never restart, regardless of SA_RESTART. The reasoning here is that the very purpose of paccept() is to wait for a connection or a signal, and that restarting in the latter case is probably never useful. (Note: Roland disagrees on this point, believing that rather paccept() should be consistent with accept() in its behavior wrt EINTR (http://thread.gmane.org/gmane.linux.kernel/723953/focus=732255).) I believe that instead, a simpler API, consistent with Ulrich's other recent additions, is preferable: accept4(int fd, struct sockaddr *sa, socklen_t *salen, ind flags); (This simpler API was originally proposed by Ulrich: http://thread.gmane.org/gmane.linux.network/92072) If this simpler API is added, then if we later decide that the sigset argument really is required, then a suitable bit in 'flags' could be added to indicate the presence of the sigset argument. At this point, I am hoping we either will get a counter-argument from Ulrich about why we really do need paccept()'s sigset argument, or that he will resubmit the original accept4() patch.

2008-09-23kexec: fix segmentation fault in kimage_add_entryJonathan Steel
A segmentation fault can occur in kimage_add_entry in kexec.c when loading a kernel image into memory. The fault occurs because a page is requested by calling kimage_alloc_page with gfp_mask GFP_KERNEL and the function may actually return a page with gfp_mask GFP_HIGHUSER. The high mem page is returned because it was swapped with the kernel page due to the kernel page being a page that will shortly be copied to. This patch ensures that kimage_alloc_page returns a page that was created with the correct gfp flags. I have verified the change and fixed the whitespace damage of the original patch.

2008-09-23x86: c1e_idle: don't mark TSC unstable if CPU has invariant TSCAndreas Herrmann
Impact: Functional TSC is marked unstable on AMD family 0x10 and 0x11 CPUs. This would be wrong because for those CPUs "invariant TSC" means: "The TSC counts at the same rate in all P-states, all C states, S0, or S1" (See "Processor BIOS and Kernel Developer's Guides" for those CPUs.)

2008-09-23x86: prevent C-states hang on AMD C1E enabled machinesThomas Gleixner
Impact: System hang when AMD C1E machines switch into C2/C3 AMD C1E enabled systems do not work with normal ACPI C-states even if the BIOS is advertising them. Limit the C-states to C1 for the ACPI processor idle code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-09-23clockevents: prevent mode mismatch on cpu onlineThomas Gleixner
Impact: timer hang on CPU online observed on AMD C1E systems When a CPU is brought online then the broadcast machinery can be in the one shot state already. Check this and setup the timer device of the new CPU in one shot mode so the broadcast code can pick up the next_event value correctly. Another AMD C1E oddity, as we switch to broadcast immediately and not after the full bring up via the ACPI cpu idle code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-09-23clockevents: check broadcast device not tick deviceThomas Gleixner
Impact: Possible hang on CPU online observed on AMD C1E machines. The broadcast setup code looks at the mode of the tick device to determine whether it needs to be shut down or setup. This is wrong when the broadcast mode is set to one shot already. This can happen when a CPU is brought online as it goes through the periodic setup first. The problem went unnoticed as sane systems do not call into that code before the switch to one shot for the clock event device happens. The AMD C1E idle routine switches over immediately and thereby shuts down the just setup device before the first interrupt happens. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-09-23clockevents: prevent stale tick_next_period for onlining CPUsThomas Gleixner
Impact: possible hang on CPU onlining in timer one shot mode. The tick_next_period variable is only used during boot on nohz/highres enabled systems, but for CPU onlining it needs to be maintained when the per cpu clock events device operates in one shot mode.

2008-09-23x86: prevent stale state of c1e_mask across CPU offline/onlineThomas Gleixner
Impact: hang which happens across CPU offline/online on AMD C1E systems. When a CPU goes offline then the corresponding bit in the broadcast mask is cleared. For AMD C1E enabled CPUs we do not reenable the broadcast when the CPU comes online again as we do not clear the corresponding bit in the c1e_mask, which keeps track which CPUs have been switched to broadcast already. So on those !$@#& machines we never switch back to broadcasting after a CPU offline/online cycle. Clear the bit when the CPU plays dead. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-09-23clockevents: prevent cpu online to interfere with nohzThomas Gleixner
Impact: rare hang which can be triggered on CPU online. tick_do_timer_cpu keeps track of the CPU which updates jiffies via do_timer. The value -1 is used to signal, that currently no CPU is doing this. There are two cases, where the variable can have this state: boot: necessary for systems where the boot cpu id can be != 0 nohz long idle sleep: When the CPU which did the jiffies update last goes into a long idle sleep it drops the update jiffies duty so another CPU which is not idle can pick it up and keep jiffies going. Using the same value for both situations is wrong, as the CPU online code can see the -1 state when the timer of the newly onlined CPU is setup. The setup for a newly onlined CPU goes through periodic mode and can pick up the do_timer duty without being aware of the nohz / highres mode of the already running system. Use two separate states and make them constants to avoid magic numbers confusion. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-09-23x86: fix 27-rc crash on vsmp due to paravirt during module loadRavikiran G Thirumalai
27-rc fails to boot up if configured to use modules. Turns out vsmp_patch was marked __init, and vsmp_patch being the pvops 'patch' routine for vsmp, a call to vsmp_patch just turns out to execute a code page with series of 0xcc (POISON_FREE_INITMEM -- int3). vsmp_patch has been marked with __init ever since pvops, however, apply_paravirt can be called during module load causing calls to freed memory location. Since apply_paravirt can only be called during init/module load, make vsmp_patch with "__init_or_module" Signed-off-by: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
