| | | | | | | | | | | | | when commit 6166c24 (usb: gadget: pxa25x_udc: convert to udc_start/udc_stop) converted this driver to udc_start/udc_stop, it failed to consider the fact that stop_activity() is called from disconnect interrupt.

* usb: musb: omap2430: fix omap_musb_mailbox glue check againAaro Koskinen2013-03-051-3/+7
| | | | | | | | | | | | | | | | | | Commit 80ab72e1 (usb: musb: omap2430: fix the readiness check in omap_musb_mailbox) made the check incorrect, as we will lose the glue/link status during the normal built-in probe order (twl4030_usb is probed after musb omap2430, but before musb core is ready). As a result, if you boot with USB cable on and load g_ether, the connection does not work as the code thinks the cable is off and the phy gets powered down immediately. This is a major regression in 3.9-rc1. So the proper check should be: exit if _glue is NULL, but if it's initialized we memorize the status, and then check if the musb core is ready.

Stefan Bader dug in this deep and found out that: "That makes it clearer as this will do reserve_memtype(...) --> pat_x_mtrr_type --> mtrr_type_lookup --> __mtrr_type_lookup And that can return -1/0xff in case of MTRR not being enabled/initialized. Which is not the case (given there are no messages for it in dmesg). This is not equal to MTRR_TYPE_WRBACK and thus becomes _PAGE_CACHE_UC_MINUS. It looks like the problem starts early in reserve_memtype: if (!pat_enabled) { /* This is identical to page table setting without PAT */ if (new_type) { if (req_type == _PAGE_CACHE_WC) *new_type = _PAGE_CACHE_UC_MINUS; else *new_type = req_type & _PAGE_CACHE_MASK; } return 0; } This would be what we want, that is clearing the PWT and PCD flags from the supported flags - if pat_enabled is disabled." This patch does that - disabling PAT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Note that this thing does *not* contribute to inode refcount; it's pinned down by dentry. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | ... otherwise the path we'd built isn't worth much. Don't accept such fids obtained from paths unless dentry is still alived by the end of the work. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
