From: Maneesh Soni <maneesh@in.ibm.com> o This patch introduces the new sysfs_dirent data structure. The sysfs_dirent is added to the dentry corresponding to each of the element which can be represented in sysfs like, kobject (directory), text or binary attributes (files), attribute groups (directory) and symlinks. o It uses dentry's d_fsdata field to attach the corresponding sysfs_dirent. o The sysfs_dirents are maintained in a tree of all the sysfs entries using the s_children and s_sibling list pointers. o This patch also changes how we access attributes and kobjects in file_operations from a given dentry, basically introducing one more level of indirection. o The sysfs_dirents are freed and the sysfs_dirent tree is updated accordingly upon the deletion of corresponding dentry. The sysfs dirents are kept alive as long as there is corresponding dentry around. The are freed when the dentry is finally out of dcache using the ->d_iput() method. o This also fixes the dentry leaks in case of error paths after sysfs has got a newly alocated (and hashed) dentry from sysfs_get_dentry() by d_drop()'ing the dentry.

From: Maneesh Soni <maneesh@in.ibm.com> o The following patch provides dumb helpers to access the corresponding kobject, attribute or binary attribute given a dentry and prepare the sysfs_file_operation methods for using sysfs_dirents. Signed-off-by:

Calling sys_restart_syscall without having taking a signal across a syscall leaves the restart_block uninitialized, allowing malicious user code to crash the kernel. FIX: Define INIT_THREAD_INFO such that restart_block.fn is set to the default do_not_restart_syscall. Committed-by: -

Fix N class SMP The main fixes are: - memory barriers to our space and control register moves - fix for the N class merced bus problem which can't have more than one PxTLB broadcast outstanding at once - make smp_call_function() wait until the function completes This now boots and runs on a 32MB N4000 in Fort Collins with 2 cpus and discontig mem support.

Add build support for new CPU families and boards. Specifically for the 527x ColdFire family, and the generic 528x CPU family. Also made the switch to -O1, gives smaller code on m68k and ColdFire platforms. Signed-off-by:

Re-work the udelay() function. On fast ColdFire CPU's we are overflowing in the calculation and getting totally bogus results. On old 68k and ColdFire CPU's we have no 32*32->64 multiply instruction. So we resort to a mul/shift calculation similar to what ARM uses. Signed-off-by:

A few updates to the m68knommu configuration: . Made the Morotola 5280 and 5282 support be a common 528x family . Add support for selecting the 527x ColdFire family (5270/5271/5274/5275) . Add support for selecting Freescale M5271EVB board . Add support for selecting Freescale M5275EVB board . Add support for selecting Sneha CPU16B board . Add support for selecting Feith SCALES and CANCAM boards . Fix some gramatical errors in help lines Signed-off-by:

Looks like Al's patch to sparsify the byteorder code prevented use of the assembler-optimised code. Not that I can blame him -- three underscores are C-coded and two underscores are assembly-optimised.

If "utf8" option was specified and app uses VFAT_IOCTL_READDIR_BOTH ioctl, utf8_wcstombs() is used. utf8_wcstombs() doesn't add the nul terminate. Then fat_ioctl_filldir() uses a wrong length of name by strlen(). This patch passes the correct length to fat_ioctl_filldir(), and doesn't use nul terminate anymore. Many helps by Alex Villacís Lasso. Thanks. Signed-off-by:
