2011-08-21OMAP4: clock: fix compile warningPaul Walmsley
Fix the following compile warning: arch/arm/mach-omap2/clock44xx_data.c: In function 'omap4xxx_clk_init': arch/arm/mach-omap2/clock44xx_data.c:3371:6: warning: 'cpu_clkflg' may be used uninitialized in this function The approach taken here is intended to work if omap4xxx_clk_init() is converted into an initcall.

2011-08-20sparc: Allow handling signals when stack is corrupted.David S. Miller
If we can't push the pending register windows onto the user's stack, we disallow signal delivery even if the signal would be delivered on a valid seperate signal stack. Add a register window save area in the signal frame, and store any unsavable windows there. On sigreturn, if any windows are still queued up in the signal frame, try to push them back onto the stack and if that fails we kill the process immediately. This allows the debug/tst-longjmp_chk2 glibc test case to pass. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-08-19OMAP4: clock: re-enable previous clockdomain enable/disable sequencePaul Walmsley
After commit 665d001338b494d6d62810aa99b4c0fa1a0884b9 ("OMAP2+: hwmod: Follow the recommended PRCM module enable sequence"), device drivers for OMAP IP blocks that do not use runtime PM can cause oopses or kernel instability[1][2]. This is because those non-runtime PM drivers do not use the hwmod code, which implements the correct IP block enable and disable sequence. Several options for dealing with this problem have been proposed: 1. Add a new field to the OMAP struct clk to mark clocks that are currently used by non-runtime PM drivers. Modify the clock code to use the old clockdomain sequence for these marked clocks. As drivers are converted to use runtime PM, remove the annotation from the clocks. 2. Similar to #1, but associate the flag with the struct omap_clk instead. 3. Add IDLEST wait support to the OMAP4 clock code, similar to the way it is implemented for OMAP2/3, and enable it in each struct clk currently used by non-runtime PM drivers. As drivers are converted to use runtime PM, remove the annotation from the clocks. 4. Do nothing; leave the problem to those responsible for the unconverted drivers. 5. Re-enable clock-based clockdomain control in the OMAP4 clock code. This would revert back to the behavior of Linux 3.0, simply with a slightly longer module enable/disable latency. Unfortunately, no approach seemed particularly good. Options 1 through 3 seemed unwise due to the following reasons: A. The OMAP struct clks are intended primarily to describe hardware clock nodes, and the intention is that no driver-specific data should be stored there (applies to #1) B. The resulting patch would have been quite large for the -rc series (applies to #1, #2, #3) C. The patch would have been a new, yet temporary hack; and similar fixes have drawn negative comments in the recent past (see for example [3]) Option 4 is undesirable because commit 665d001338b494d6d62810aa99b4c0fa1a0884b9 ("OMAP2+: hwmod: Follow the recommended PRCM module enable sequence") has resulted in a less stable kernel; and kernel stability is more important than OMAP4 power management. Option 5 is the approach taken in this patch. This seemed to be the least intrusive approach for 3.1-rc. The approach in this patch was originally proposed by Ohad Ben-Cohen <ohad@wizery.com>. I'm simply writing the commit message and passing it along. ... Thanks to Luciano Coelho <coelho@ti.com> for reporting the problem.

2011-08-19OMAP: clockdomain: Wait for powerdomain to be ON when using clockdomain ↵Santosh Shilimkar
force wakeup While using clockdomain force wakeup method, not waiting for powerdomain to be effectively ON may end up locking the clockdomain FSM until a next wakeup event occurs.

2011-08-17xen/x86: replace order-based range checking of M2P table by linear oneJan Beulich
The order-based approach is not only less efficient (requiring a shift and a compare, typical generated code looking like this mov eax, [machine_to_phys_order] mov ecx, eax shr ebx, cl test ebx, ebx jnz ... whereas a direct check requires just a compare, like in cmp ebx, [machine_to_phys_nr] jae ... ), but also slightly dangerous in the 32-on-64 case - the element address calculation can wrap if the next power of two boundary is sufficiently far away from the actual upper limit of the table, and hence can result in user space addresses being accessed (with it being unknown what may actually be mapped there). Additionally, the elimination of the mistaken use of fls() here (should have been __fls()) fixes a latent issue on x86-64 that would trigger if the code was run on a system with memory extending beyond the 44-bit boundary.

The sparc32 version of arch_write_unlock() is just a plain assignment. Unfortunately this allows the compiler to schedule side-effects in a protected region to occur after the HW-level unlock, which is broken. E.g., the following trivial test case gets miscompiled: #include <linux/spinlock.h> rwlock_t lock; int counter; void foo(void) { write_lock(&lock); ++counter; write_unlock(&lock); } Fixed by adding a compiler memory barrier to arch_write_unlock(). The sparc64 version combines the barrier and assignment into a single asm(), and implements the operation as a static inline, so that's what I did too.

This patch fixes L2 Cache size calculations for L2C-210, L2C-310 and PL310, by changing the L2X0_AUX_CTRL_WAY_SIZE_MASK from 2 bits to 3 bits. The Auxiliary Control Register for L2C-210, L2C-310 and PL310 has 3bits [19:17] for Way size, however the existing code only uses 2 bits to get this value. This results in incorrect cachesize calculations. It also results in performing operations on the whole cache when we erroneously decide that the range is big enough (due to l2x0_size being too small) and also prints incorrect cachesize.

2011-08-12ARM: cache: detect VIPT aliasing I-cache on ARMv6Will Deacon
The current cache detection code does not check for an aliasing I-cache if the D-cache is found to be VIPT aliasing. This patch fixes the problem by always checking for an aliasing I-cache on v6 and later. Signed-off-by: Will Deacon <will.deacon@arm.com>
2011-08-12ARM: twd: register clockevents device before enabling PPIWill Deacon
The smp_twd clockevents driver currently enables the local timer PPI before the clockevents device is registered. This can lead to a kernel panic if a spurious timer interrupt is generated before registration has completed since the kernel will treat it as an IPI timer. This patch moves the clockevents device registration before the IRQ unmasking so that we can always handle timer interrupts once they can occur.

2011-08-12ARM: realview: ensure visibility of writes during resetWill Deacon
The various reset routines in mach-realview rely on an FPGA to power-cycle the board after writing some magic runes to memory-mapped registers. This patch adds a dsb() following the writes, so that they become visible before we mdelay(1000) in the arch_reset code. Without this patch, the timeout would expire sporadically, causing the reset to fail. Signed-off-by: Will Deacon <will.deacon@arm.com>
2011-08-12ARM: perf: make name of arm_pmu_type consistentMark Rutland
Commit f12482c9 ("ARM: 6974/1: pmu: refactor reservation") changed {release,reserve}_pmu to take an enum arm_pmu_type as a parameter, but inconsistently named the parameter `type' or `device'. It would be nice if these were consistent. This patch makes use of enum arm_pmu_type consistent, always using `type'. Related printks are updated, explicitly mentioning `type' also.

2011-08-12ARM: perf: fix prototype of release_pmuMark Rutland
Commit f12482c9 ("ARM: 6974/1: pmu: refactor reservation") changed the prototype of release_pmu, but missed the stub for when CONFIG_CPU_HAS_PMU is not selected by the platform. This patch changes the prototype of the stub, preventing possible build failures when CONFIG_CPU_HAS_PMU is not selected.
