2011-11-02um: finish conversion to mcontext_tAl Viro
now we don't mix host and guest signal frame layouts anymore; moreover, we don't need host's struct sigcontext at all. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>

2011-11-02um: simplify set_handler()Al Viro
For one thing, we always block the same signals (IRQ ones - IO, WINCH, VTALRM), so there's no need to pass sa_mask elements in arguments. For another, the flags depend only on whether it's an IRQ signal or not (we add SA_RESTART for them).

2011-11-02um: don't bother blocking SIGARLM and SIGUSR1Al Viro

only sysdep/sigcontext.h uses it and very few definitions are actually used. The rest refers to symbols that don't even exist anymore anyway. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>

2011-11-02um: series of __get_user() is costly in sigframe handlingAl Viro
It's not x86, where __get_user() is a single dereference; here it's a single ptrace(2) call in host, which obviously costs a lot more. IOW, it's cheaper to do copy_{to,from}_user() once than bother with fields one by one... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>

2011-11-02vfs: add d_prune dentry operationSage Weil
This adds a d_prune dentry operation that is called by the VFS prior to pruning (i.e. unhashing and killing) a hashed dentry from the dcache. Wrap dentry_lru_del() and use the new _prune() helper in the cases where we are about to unhash and kill the dentry. This will be used by Ceph to maintain a flag indicating whether the complete contents of a directory are contained in the dcache, allowing it to satisfy lookups and readdir without addition server communication. Renumber a few DCACHE_* #defines to group DCACHE_OP_PRUNE with the other DCACHE_OP_ bits. Signed-off-by: Sage Weil <sage@newdream.net> Signed-off-by: Christoph Hellwig <hch@lst.de>

2011-11-02readlinkat: ensure we return ENOENT for the empty pathname for normal lookupsAndy Whitcroft
Since the commit below which added O_PATH support to the *at() calls, the error return for readlink/readlinkat for the empty pathname has switched from ENOENT to EINVAL: commit 65cfc6722361570bfe255698d9cd4dccaf47570d Author: Al Viro <viro@zeniv.linux.org.uk> Date: Sun Mar 13 15:56:26 2011 -0400 readlinkat(), fchownat() and fstatat() with empty relative pathnames This is both unexpected for userspace and makes readlink/readlinkat inconsistant with all other interfaces; and inconsistant with our stated return for these pathnames. As the readlinkat call does not have a flags parameter we cannot use the AT_EMPTY_PATH approach used in the other calls. Therefore expose whether the original path is infact entry via a new user_path_at_empty() path lookup function. Use this to determine whether to default to EINVAL or ENOENT for failures.

2011-11-02vmwgfx: Reinstate the update_layout ioctlThomas Hellstrom
We need to redefine a connector as "connected" if it matches a window in the host preferred GUI layout. Otherwise "smart" window managers would turn on Xorg outputs that we don't want to be on. This reinstates the update_layout and adds the following information to the modesetting system. a) Connection status <-> Equivalent to real hardware connection status b) Preferred mode <-> Equivalent to real hardware reading EDID c) Host window position <-> Equivalent to a real hardware scanout address dynamic register. It should be noted that there is no assumption here about what should be displayed and where. Only how to access the host windows. This also bumps minor to signal availability of the new IOCTL.
