It seems that pmac_zilog.c got missed in the dev.power_state to dev.power.power_state conversion. This patch makes that change, and also fixes a problem where it would not compile if CONFIG_MAGIC_SYSRQ was set but CONFIG_SERIAL_CORE_CONSOLE was not. Signed-off-by:

Using the "resume" kernel parameter together with an initramfs revealed a bug that causes removal of the /sys directory in the initramfs' tmpfs, making the system unbootable. The source of the problem is that the try_name() function removes the /sys directory unconditionally, instead of removing it only when it has been created by try_name(). The attached patch only removes /sys if it has been created before. Signed-off-by:

10 weeks ago, http://linux.bkbits.com:8080/linux-2.5/cset@415b3380pxf4sB97gM8ujLqDxi6GfQ The patch was mostly right, and fixed a real problem, but missed a bit. It passed the job of checking if an inode had a current alias off to d_find_alias instead of open-coding it in d_alloc_anon. However there is one case where d_alloc_anon would not return the right dentry. That case being when the inode was for the root of the filesystem. The root is a special case because it is not hashed. All other dentries that are not hashed are quite un-interesting: There are "unlinked" but not yet closed. The root of a filesystem is unhashed, but is interesting. Allowing d_find_alias to return an unhashed alias for a directory solves this problem. It is safe because callers of d_find_alias on a directory inode either have a name for the inode already (so finding an unlinked directory by mistake is impossible) or will soon be looking for a name and will drop the dentry if a name is not found.

I was looking through the radix tree code and came across what I think is a bug in radix_tree_delete. for (idx = 0; idx < RADIX_TREE_TAG_LONGS; idx++) { if (pathp[0].node->tags[tag][idx]) { tags[tag] = 1; nr_cleared_tags--; break; } } The above loop should only be executed if tags[tag] is zero. Otherwise, when walking up the tree, we can decrement nr_cleared_tags twice or more for the same value of tag, thus potentially exiting the outer loop too early. Ensure that nr_cleared_tags is only decremented once for each tag. Signed-off-by:Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by:

Jeff Dike authored
From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> This one covers the fact, that the SIGSEGV signal, which is created by force_sigsegv() in case of an error in handle_signal(), is not delivered to the user immediately. In the worst case it even could be masked if a sigprocmask() systemcall follows immediately after return from kernel. The patch is relevant for other architectures, too. Signed-off-by:

Jeff Dike authored
From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> If the user stack limit is reached or the signal stack assigned with sigaltstack() is invalid when a user signal handler with SA_ONSTACK has to be started, the signal mask of the interrupted user program is modified. This happens because the mask, that should be used with the handler only, is written to "current->blocked" even if the handler could not be started. But without a handler, no rewrite of the original mask at sys_sigreturn will be done. A slightly different case is sys_sigsuspend(), where the mask is already modified when kern_do_signal() is started. "*oldset" and "current->blocked" are not equal here and thus current->blocked has to be set to *oldset, if an error occurs in handle_signal(). For both cases I've written small tests, and with the patch the result is OK. This issue is relevant for other architectures too (e.g. i386, I've seen). Signed-off-by:

From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> Change the do_signal interface to eliminate its argument. Also, remove the calls from the system call handlers since they are redundant.

Jeff Dike authored
This patch fixes a bug introduced in the last batch of signal fixes. The system call return value should only be reset if called diectly from a system call, i.e. sigsuspend. The fixes added earlier caused any interrupted non-zero system call return to be reset, confusing fork and vfork, among others. Signed-off-by:

This patchset was originally from NIIBE Yutaka. These patch update the m32r kernel for a new bootloader "m32r-g00ff". The "m32r-g00ff" has been written and developed by NIIBE Yutaka, and released under the GPL from http://www.gniibe.org/. So far, it supports two types of booting operations, CF boot and Network boot (HTTP boot). * CF boot - boot from CompactFlash or Microdrive(TM) We can boot a kernel from CF device. To make use of m32r-g00ff, we just put a first stage IPL(initial program loader) into a flash memory, and a secondary bootloader into CF media device. Currently, LILO-21.4.4 can be used to write m32r-g00ff into the boot sector of CF device on a cross development environment. * HTTP boot - boot via network with HTTP protocol By using m32r-g00ff, we can download and boot a kernel image from a web-server. The m32r-g00ff downloads a kernel image from a given URL, resolving the webserver's IP address by DNS. As a preparation, we just place a secondary bootloader binary and a kernel image on the webserver. - Position-independent zImage support; this aims at removing constraints of zImage(vmlinuz)'s location.
