2005-04-18[PATCH] usb suspend updates (interface suspend)David Brownell
This is the first of a few installments of PM API updates to match the recent switch to "pm_message_t". This installment primarily affects USB device drivers (for USB interfaces), and it changes the handful of drivers which currently implement suspend methods: - <linux/usb.h> and usbcore, signature change - Some drivers only changed the signature, net effect this just shuts up "sparse -Wbitwise": * hid-core * stir4200 - Two network drivers did that, and also grew slightly more featureful suspend code ... they now properly shut down their activities. (As should stir4200...) * pegasus * usbnet Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks to me like it's missing a request to turn it on, vs just configuring it. The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

2005-04-18[PATCH] usb resume fixesDavid Brownell
This has a variety of updates to the shared suspend/resume code for PCI based USB host controllers. - Cope with pm_message_t replacing the target system state. This is actually a loss of functionality; PCI D1 and D2 states will no longer be used, and it's no longer knowable that D3cold is on the way so power will be lost. - Most importantly, some of the resume paths are reworked and cleaned up. They're now an exact mirror of suspend paths, and more care is taken to ensure the hardware is reactivated before the hardware re-enables interrupts. Plus comment and diagnostic cleanups; there are some nasty cases here especially combined with swsusp, now they're somewhat commented.

2005-04-18[PATCH] sparc64: Fix statDavid S. Miller
Like Alpha, sparc64's struct stat was defined before we had the nanosecond et al. fields added. So like Alpha I have to cons up a struct stat64 to get this stuff. I'll work on the glibc bits soon.

2005-04-18[PATCH] Add 32-bit compatibility for NFSv4 mountDavid Howells
This adds 32-bit compatibility for mounting an NFSv4 mount on a 64-bit kernel (such as happens with PPC64). The problem is that the mount data for the NFS4 mount process includes auxilliary data pointers, probably because the NFS4 mount data may conceivably exceed PAGE_SIZE in size - thus breaking against the hard limit imposed by sys_mount().

2005-04-18[PATCH] SELinux: fix deadlock on dcache lockStephen Smalley
This fixes a deadlock on the dcache lock detected during testing at IBM by moving the logging of the current executable information from the SELinux avc_audit function to audit_log_exit (via an audit_log_task_info helper) for processing upon syscall exit. For consistency, the patch also removes the logging of other task-related information from avc_audit, deferring handling to audit_log_exit instead. This allows simplification of the avc_audit code, allows the exe information to be obtained more reliably, always includes the comm information (useful for scripts), and avoids including bogus task information for checks performed from irq or softirq.

2005-04-17[PATCH] sparc64: Reduce ptrace cache flushingDavid S. Miller
We were flushing the D-cache excessively for ptrace() processing and this makes debugging threads so slow as to be totally unusable. All process page accesses via ptrace() go via access_process_vm(). This routine, for each process page, uses get_user_pages(). That in turn does a flush_dcache_page() on the child pages before we copy in/out the ptrace request data. Therefore, all we need to do after the data movement is: 1) Flush the D-cache pages if the kernel maps the page to a different color than userspace does. 2) If we wrote to the page, we need to flush the I-cache on older cpus. Previously we just flushed the entire cache at the end of a ptrace() request, and that was beyond stupid. Signed-off-by: David S.

2005-04-17[PATCH] sparc: Fix PTRACE_CONT bogosityDavid S. Miller
SunOS aparently had this weird PTRACE_CONT semantic which we copied. If the addr argument is something other than 1, it sets the process program counter to whatever that value is. This is different from every other Linux architecture, which don't do anything with the addr and data args. This difference in particular breaks the Linux native GDB support for fork and vfork tracing on sparc and sparc64. There is no interest in running SunOS binaries using this weird PTRACE_CONT behavior, so just delete it so we behave like other platforms do. Signed-off-by: David S.

2005-04-17[PATCH] sparc64: Do not flush dcache for ZERO_PAGE.David S. Miller
This case actually can get exercised a lot during an ELF coredump of a process which contains a lot of non-COW'd anonymous pages. GDB has this test case which in partiaular creates near terabyte process full of ZERO_PAGEes. It takes forever to just walk through the page tables because of all of these spurious cache flushes on sparc64. With this change it takes only a second or so. Signed-off-by: David S.

2005-04-17[PATCH] revert fs/char_dev.c CONFIG_BASE_FULL changeDavid Brownell
This reverts a fs/char_dev.c patch that was merged into BK on March 3. The problem is that it breaks things ... __register_chrdev_region() has a block of code, commented "temporary" for over two years now, which fails rudely during PCMCIA initialization or other register_chrdev() calls, because it doesn't "degrade to linked list". This keeps whole subsystems from working. A real fix to that "temporary" code should be possible, using some better scheme to allocate major numbers, but it's not something I want to spend time on just now.

2005-04-16[PATCH] jbd dirty buffer leak fixakpm@osdl.org
This fixes the lots-of-fsx-linux-instances-cause-a-slow-leak bug. It's been there since 2.6.6, caused by: ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.5/2.6.5-mm4/broken-out/jbd-move-locked-buffers.patch That patch moves under-writeout ordered-data buffers onto a separate journal list during commit. It took out the old code which was based on a single list. The old code (necessarily) had logic which would restart I/O against buffers which had been redirtied while they were on the committing transaction's t_sync_datalist list. The new code only writes buffers once, ignoring redirtyings by a later transaction, which is good. But over on the truncate side of things, in journal_unmap_buffer(), we're treating buffers on the t_locked_list as inviolable things which belong to the committing transaction, and we just leave them alone during concurrent truncate-vs-commit. The net effect is that when truncate tries to invalidate a page whose buffers are on t_locked_list and have been redirtied, journal_unmap_buffer() just leaves those buffers alone. truncate will remove the page from its mapping and we end up with an anonymous clean page with dirty buffers, which is an illegal state for a page. The JBD commit will not clean those buffers as they are removed from t_locked_list. The VM (try_to_free_buffers) cannot reclaim these pages. The patch teaches journal_unmap_buffer() about buffers which are on the committing transaction's t_locked_list. These buffers have been written and I/O has completed. We can take them off the transaction and undirty them within the context of journal_invalidatepage()->journal_unmap_buffer(). Acked-by: "Stephen C.
