2013-06-21ARM: Kirkwood: Fix the internal register ranges translationEzequiel Garcia
Although the internal register window size is 1 MiB, the previous ranges translation for the internal register space had a size of 0x4000000. This was done to allow the crypto and nand node to access the corresponding 'sram' and 'nand' decoding windows. In order to describe the hardware more accurately, we declare the real 1 MiB internal register space in the ranges, and add a translation entry for the nand node to access the 'nand' window. This commit will make future improvements on the MBus DT binding easier. Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>

2013-06-21ARM: ux500: Correct the EN_3v3 regulator's on/off GPIOLee Jones
When this node was added, the AB8500 GPIO driver was pretty broken. As a hack, we pretended that NOMADIK GPIO 26 was the correct on/off pin, as it was unused. It worked because AB8500 GPIO 26 was in an 'always on from boot' state. Now the AB8500 GPIO driver is working, the default state for all the pins is 'off'. Let's flip back over to use the correct GPIO which is _actually_ attached to the regulator. We're also taking the opportunity to straighten out some formatting misdemeanours, swapping spaces for tabs.

2013-06-21tick: Fix tick_broadcast_pending_mask not clearedDaniel Lezcano
The recent modification in the cpuidle framework consolidated the timer broadcast code across the different drivers by setting a new flag in the idle state. It tells the cpuidle core code to enter/exit the broadcast mode for the cpu when entering a deep idle state. The broadcast timer enter/exit is no longer handled by the back-end driver. This change made the local interrupt to be enabled *before* calling CLOCK_EVENT_NOTIFY_EXIT. On a tegra114, a four cores system, when the flag has been introduced in the driver, the following warning appeared: WARNING: at kernel/time/tick-broadcast.c:578 tick_broadcast_oneshot_control CPU: 2 PID: 0 Comm: swapper/2 Not tainted 3.10.0-rc3-next-20130529+ #15 [<c00667f8>] (tick_broadcast_oneshot_control+0x1a4/0x1d0) from [<c0065cd0>] (tick_notify+0x240/0x40c) [<c0065cd0>] (tick_notify+0x240/0x40c) from [<c0044724>] (notifier_call_chain+0x44/0x84) [<c0044724>] (notifier_call_chain+0x44/0x84) from [<c0044828>] (raw_notifier_call_chain+0x18/0x20) [<c0044828>] (raw_notifier_call_chain+0x18/0x20) from [<c00650cc>] (clockevents_notify+0x28/0x170) [<c00650cc>] (clockevents_notify+0x28/0x170) from [<c033f1f0>] (cpuidle_idle_call+0x11c/0x168) [<c033f1f0>] (cpuidle_idle_call+0x11c/0x168) from [<c000ea94>] (arch_cpu_idle+0x8/0x38) [<c000ea94>] (arch_cpu_idle+0x8/0x38) from [<c005ea80>] (cpu_startup_entry+0x60/0x134) [<c005ea80>] (cpu_startup_entry+0x60/0x134) from [<804fe9a4>] (0x804fe9a4) I don't have the hardware, so I wasn't able to reproduce the warning but after looking a while at the code, I deduced the following: 1. the CPU2 enters a deep idle state and sets the broadcast timer 2. the timer expires, the tick_handle_oneshot_broadcast function is called, setting the tick_broadcast_pending_mask and waking up the idle cpu CPU2 3. the CPU2 exits idle handles the interrupt and then invokes tick_broadcast_oneshot_control with CLOCK_EVENT_NOTIFY_EXIT which runs the following code: [...] if (dev->next_event.tv64 == KTIME_MAX) goto out; if (cpumask_test_and_clear_cpu(cpu, tick_broadcast_pending_mask)) goto out; [...] So if there is no next event scheduled for CPU2, we fulfil the first condition and jump out without clearing the tick_broadcast_pending_mask. 4. CPU2 goes to deep idle again and calls tick_broadcast_oneshot_control with CLOCK_NOTIFY_EVENT_ENTER but with the tick_broadcast_pending_mask set for CPU2, triggering the warning. The issue only surfaced due to the modifications of the cpuidle framework, which resulted in interrupts being enabled before the call to the clockevents code. If the call happens before interrupts have been enabled, the warning cannot trigger, because there is still the event pending which caused the broadcast timer expiry. Move the check for the next event below the check for the pending bit, so the pending bit gets cleared whether an event is scheduled on the cpu or not.

2013-06-21spi/pxa2xx: fix memory corruption due to wrong size used in devm_kzalloc()Mika Westerberg
ACPI part of the driver accidentally used sizeof(*ssp) instead of the correct sizeof(*pdata). This leads to nasty memory corruptions like the one below: BUG: unable to handle kernel paging request at 0000000749fd30b8 IP: [<ffffffff813fe8a1>] __list_del_entry+0x31/0xd0 PGD 0 Oops: 0000 [#1] PREEMPT SMP Modules linked in: CPU: 0 PID: 30 Comm: kworker/0:1 Not tainted 3.10.0-rc6v3.10-rc6_sdhci_modprobe+ #443 task: ffff8801483a0940 ti: ffff88014839e000 task.ti: ffff88014839e000 RIP: 0010:[<ffffffff813fe8a1>] [<ffffffff813fe8a1>] __list_del_entry+0x31/0xd0 RSP: 0000:ffff88014839fde8 EFLAGS: 00010046 RAX: ffff880149fd30b0 RBX: ffff880149fd3040 RCX: dead000000200200 RDX: 0000000749fd30b0 RSI: ffff880149fd3058 RDI: ffff88014834d640 RBP: ffff88014839fde8 R08: ffff88014834d640 R09: 0000000000000001 R10: ffff8801483a0940 R11: 0000000000000001 R12: ffff880149fd3040 R13: ffffffff810e0b30 R14: ffff8801483a0940 R15: ffff88014834d640 FS: 0000000000000000(0000) GS:ffff880149e00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000168 CR3: 0000000001e0b000 CR4: 00000000001407f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Stack: ffff88014839fe48 ffffffff810e0baf ffffffff81120abd ffff88014839fe20 ffff8801483a0940 ffff8801483a0940 ffff8801483a0940 ffff8801486b1c90 ffff88014834d640 ffffffff810e0b30 0000000000000000 0000000000000000 Call Trace: [<ffffffff810e0baf>] worker_thread+0x7f/0x390 [<ffffffff81120abd>] ? trace_hardirqs_on+0xd/0x10 [<ffffffff810e0b30>] ? manage_workers.isra.22+0x2b0/0x2b0 [<ffffffff810e6c09>] kthread+0xd9/0xe0 [<ffffffff810f93df>] ? local_clock+0x3f/0x50 [<ffffffff810e6b30>] ? kthread_create_on_node+0x110/0x110 [<ffffffff818c5dec>] ret_from_fork+0x7c/0xb0 [<ffffffff810e6b30>] ? kthread_create_on_node+0x110/0x110 Fix this by using the right structure size in devm_kzalloc().

2013-06-21arm: add basic support for Rockchip RK3066a boardsHeiko Stuebner
This adds a generic devicetree board file and a dtsi for boards based on the RK3066a SoCs from Rockchip. Apart from the generic parts (gic, clocks, pinctrl) the only components currently supported are the timers, uarts and mmc ports (all DesignWare- based).

2013-06-21arm: Add basic clocks for Rockchip rk3066a SoCsHeiko Stuebner
This adds a basic clock setup for rk3066a SoCs. Only the gates are set up currently, as the mux and dividers should use the upcoming generic devicetree bindings. Clocks whose rates need to be known are supplied by fixed-rate "dummy"-clocks that provide the correct rate. This is uncritical insofar that the only bootloader currently in existence for Rockchip devices is the propietary Rockchip one that always setups the clocks in the necessary way.

2013-06-20x86, fpu: Use static_cpu_has_safe before alternativesBorislav Petkov
The call stack below shows how this happens: basically eager_fpu_init() calls __thread_fpu_begin(current) which then does if (!use_eager_fpu()), which, in turn, uses static_cpu_has. And we're executing before alternatives so static_cpu_has doesn't work there yet. Use the safe variant in this path which becomes optimal after alternatives have run. WARNING: at arch/x86/kernel/cpu/common.c:1368 warn_pre_alternatives+0x1e/0x20() You're using static_cpu_has before alternatives have run!

2013-06-20x86: Add a static_cpu_has_safe variantBorislav Petkov
We want to use this in early code where alternatives might not have run yet and for that case we fall back to the dynamic boot_cpu_has. For that, force a 5-byte jump since the compiler could be generating differently sized jumps for each label.

2013-06-20x86: Sanity-check static_cpu_has usageBorislav Petkov
static_cpu_has may be used only after alternatives have run. Before that it always returns false if constant folding with __builtin_constant_p() doesn't happen. And you don't want that. This patch is the result of me debugging an issue where I overzealously put static_cpu_has in code which executed before alternatives have run and had to spend some time with scratching head and cursing at the monitor. So add a jump to a warning which screams loudly when we use this function too early. The alternatives patch that check away in conjunction with patching the rest of the kernel image.

If we want to have an overarching option, it should be an option which selects other options, not as a group option in the source code. ] Signed-off-by: Borislav Petkov <bp@suse.de> Link: http://lkml.kernel.org/r/1370772454-6106-4-git-send-email-bp@alien8.de Signed-off-by: H.
