This requires the addition\nof new URB flag bits to describe the kind of mapping needed, since we\nhave to call dma_map_sg() if the HCD supports native scatter-gather\noperation and dma_map_page() if it doesn\u0027t. The nice thing about\nhaving the new flags is that they simplify the testing for unmapping.\n\nThe patch removes the only caller of usb_buffer_[un]map_sg(), so those\nfunctions are #if\u0027ed out. A later patch will remove them entirely.\n\nAs a result of this change, urb-\u003esg will be set in situations where\nit wasn\u0027t set previously. Hence the xhci and whci drivers are\nadjusted to test urb-\u003enum_sgs instead, which retains its original\nmeaning and is nonzero only when the HCD has to handle a scatterlist.\n\nFinally, even when a submission error occurs we don\u0027t want to hand\nURBs to usbmon before they are unmapped. The submission path is\nrearranged so that map_urb_for_dma() is called only for non-root-hub\nURBs and unmap_urb_for_dma() is called immediately after a submission\nerror. This simplifies the error handling.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCC: \u003cstable@kernel.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n\n" }, { "commit": "3a229eb13984a2950ee47fb827c8ed1d654b9d68", "tree": "33c12dc014ae7b741e0c2d851bf7763ef71ee627", "parents": [ "0fb2c2a1692b8f77be25d38f8802b0142cb6e6bc" ], "author": { "name": "Heikki Krogerus", "email": "ext-heikki.krogerus@nokia.com", "time": "Mon May 03 09:13:01 2010 +0300" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Thu May 20 13:21:36 2010 -0700" }, "message": "usb: otg: add global ULPI register definitions\n\nDefinitions for registers defined by ULPI specification v1.1.\n\nSigned-off-by: Heikki Krogerus \u003cext-heikki.krogerus@nokia.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "71adf118946957839a13aa4d1094183e05c6c094", "tree": "b99d1113b8a36da96fc7b498b2cea39fcc440914", "parents": [ "e49bbce133a049f6f325db6b0cee49f406d03a6e" ], "author": { "name": "Fabien Chouteau", "email": "fabien.chouteau@barco.com", "time": "Thu Apr 08 09:31:15 2010 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Thu May 20 13:21:35 2010 -0700" }, "message": "USB: gadget: add HID gadget driver\n\ng_hid is a USB gadget driver implementing the Human Interface Device class\nspecification.

To fix it\nright way we need to mark _dentry_ as unsuitable for mounting\nupon; new flag (DCACHE_CANT_MOUNT) is protected by d_flags and\ni_mutex on the inode in question. Set it (with dont_mount(dentry))\nin unlink/rmdir/etc., check (with cant_mount(dentry)) in places\nin namespace.c that used to check for S_DEAD. Setting S_DEAD\nis still needed in places where we used to set it (for directories\ngetting killed), since we rely on it for readdir/rmdir race\nprevention.\n\n2) rename()/mount() protection has another bogosity - we unhash\nthe target before we\u0027d checked that it\u0027s not a mountpoint. Fixed.\n\n3) ancient bogosity in pivot_root() - we locked i_mutex on the\nright directory, but checked S_DEAD on the different (and wrong)\none.

For x86_64, a fork will result in the task-\u003estack_start\nvalue being updated to the current user top of stack and not the stack\nstart address. This unpredictability of the stack_start value makes\nit worthless. That includes the intended use of showing how much stack\nspace a thread has.\n\nOther architectures will get different values. As an example, ia64\ngets 0. The do_fork() and copy_process() functions appear to treat the\nstack_start and stack_size parameters as architecture specific.\n\nI only partially reverted c44972f1 (\"procfs: disable per-task stack usage\non NOMMU\") . If I had completely reverted it, I would have had to change\nmm/Makefile only build pagewalk.o when CONFIG_PROC_PAGE_MONITOR is\nconfigured. Since I could not test the builds without significant effort,\nI decided to not change mm/Makefile.\n\nI only partially reverted 89240ba0 (\"x86, fs: Fix x86 procfs stack\ninformation for threads on 64-bit\") .
