Merge tag 'omap-fixes-a2-for-v3.8-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8-rc2/fixes Some OMAP PRCM and sparse fixes against v3.8-rc1. A basic set of test logs are available here: http://www.pwsan.com/omap/testlogs/prcm_fixes_b_3.8-rc/20130102120724/ The 3730 Beagle XM here has an intermittent failure mounting SD root, but the suspicion right now is that this is due to a failing SD card, rather than any change introduced by these patches. This second version includes a few changes requested by Tony Lindgren.

Pull LED fix from Bryan Wu. * 'fixes-for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds: leds: leds-gpio: set devm_gpio_request_one() flags param correctly
-
Javier Martinez Canillas authored
commit a99d76f9 leds: leds-gpio: use gpio_request_one changed the leds-gpio driver to use gpio_request_one() instead of gpio_request() + gpio_direction_output() Unfortunately, it also made a semantic change that breaks the leds-gpio driver. The gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | (led_dat->active_low ^ state) Since GPIOF_DIR_OUT is 0, the final flags value will just be the XOR'ed value of led_dat->active_low and state. This value were used to distinguish between HIGH/LOW output initial level and call gpio_direction_output() accordingly. With this new semantic gpio_request_one() will take the flags value of 1 as a configuration of input direction (GPIOF_DIR_IN) and will call gpio_direction_input() instead of gpio_direction_output(). int gpio_request_one(unsigned gpio, unsigned long flags, const char *label) { .. if (flags & GPIOF_DIR_IN) err = gpio_direction_input(gpio); else err = gpio_direction_output(gpio, (flags & GPIOF_INIT_HIGH) ? 1 : 0); .. } The right semantic is to evaluate led_dat->active_low ^ state and set the output initial level explicitly.

Paul Walmsley authored
On OMAP2xxx chips, the register bitfields for the PM_PWSTCTRL_*.POWERSTATE and PM_PWSTST_*.LASTSTATEENTERED are different than those used on OMAP3/4. The order is reversed. So, for example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0 indicates 'OFF'. Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on OMAP3/4, 0x3 indicates 'ON'. To fix this, we treat the OMAP3/4 values as the powerdomain API values, and create new low-level powerdomain functions for the OMAP2xxx chips which translate between the OMAP2xxx values and the OMAP3/4 values. Without this patch, the conversion of the OMAP2xxx PM code to the functional powerstate code results in a non-booting kernel. Signed-off-by:

The ETM/ETB drivers for OMAP3, enable the emu_src_ck clock in order to access the ETM/ETB hardware. The emu_src_ck should enable the EMU clock domain so that the ETM/ETB hardware is accessible. However, currently when enabling the emu_src_ck the EMU clock domain is not being enabled and so the ETM/ETB drivers are failing. Add enable/disable clock functions to enable the EMU clock domain when enabling the emu_src_ck. Signed-off-by:

Hugh Dickins authored
Recently I suggested using "mount -o remount,mpol=local /tmp" in NUMA mempolicy testing. Very nasty. Reading /proc/mounts, /proc/pid/mounts or /proc/pid/mountinfo may then corrupt one bit of kernel memory, often in a page table (causing "Bad swap" or "Bad page map" warning or "Bad pagetable" oops), sometimes in a vm_area_struct or rbnode or somewhere worse. "mpol=prefer" and "mpol=prefer:Node" are equally toxic. Recent NUMA enhancements are not to blame: this dates back to 2.6.35, when commit e17f74af "mempolicy: don't call mpol_set_nodemask() when no_context" skipped mpol_parse_str()'s call to mpol_set_nodemask(), which used to initialize v.preferred_node, or set MPOL_F_LOCAL in flags. With slab poisoning, you can then rely on mpol_to_str() to set the bit for node 0x6b6b, probably in the next page above the caller's stack. mpol_parse_str() is only called from shmem_parse_options(): no_context is always true, so call it unused for now, and remove !no_context code. Set v.nodes or v.preferred_node or MPOL_F_LOCAL as mpol_to_str() might expect. Then mpol_to_str() can ignore its no_context argument also, the mpol being appropriately initialized whether contextualized or not. Rename its no_context unused too, and let subsequent patch remove them (that's not needed for stable backporting, which would involve rejects). I don't understand why MPOL_LOCAL is described as a pseudo-policy: it's a reasonable policy which suffers from a confusing implementation in terms of MPOL_PREFERRED with MPOL_F_LOCAL. I believe this would be much more robust if MPOL_LOCAL were recognized in switch statements throughout, MPOL_F_LOCAL deleted, and MPOL_PREFERRED use the (possibly empty) nodes mask like everyone else, instead of its preferred_node variant (I presume an optimization from the days before MPOL_LOCAL). But that would take me too long to get right and fully tested. Signed-off-by:

Eric Wong authored
EPOLL_CTL_MOD sets the interest mask before calling f_op->poll() to ensure events are not missed. Since the modifications to the interest mask are not protected by the same lock as ep_poll_callback, we need to ensure the change is visible to other CPUs calling ep_poll_callback. We also need to ensure f_op->poll() has an up-to-date view of past events which occured before we modified the interest mask. So this barrier also pairs with the barrier in wq_has_sleeper(). This should guarantee either ep_poll_callback or f_op->poll() (or both) will notice the readiness of a recently-ready/modified item.
