REGPARM has already gotten much testing, what about removing the dependency on EXPERIMENTAL? Additionally, this patch does: - remove the useless "default n" - remove note regarding binary only modules (nowadays, there are even some binary only modules compiled with REGPARM=y available) Signed-off-by:

This patch address several issues in the current BSD Secure Levels code: o plaintext_to_sha1: Missing check for a NULL return from __get_free_page o passwd_write_file: A page is leaked if the password is wrong. o fix securityfs registration order o seclvl_init is a mess and can't properly tolerate failures, failure path is upside down (deldif and delf should be switched) Cleanups: o plaintext_to_sha1: Use buffers passed in o passwd_write_file: Use kmalloc() instead of get_zeroed_page() o passwd_write_file: hashedPassword comparison is just memcmp o s/ENOSYS/EINVAL/ o misc (akpm: after some discussion it appears that the BSD secure levels feature should be scheduled for removal. But for now, let's fix these problems up). Signed-off-by:

free_hba() sets hba[i] to NULL, the dereference afterwards results in this crash.

We have noticed lockups during boot when stress testing kexec on ppc64. Two cpus would deadlock in scheduler code trying to grab already taken spinlocks. The double_rq_lock code uses the address of the runqueue to order the taking of multiple locks. This address is a per cpu variable: if (rq1 < rq2) { spin_lock(&rq1->lock); spin_lock(&rq2->lock); } else { spin_lock(&rq2->lock); spin_lock(&rq1->lock); } On the other hand, the code in wake_sleeping_dependent uses the cpu id order to grab locks: for_each_cpu_mask(i, sibling_map) spin_lock(&cpu_rq(i)->lock); This means we rely on the address of per cpu data increasing as cpu ids increase. While this will be true for the generic percpu implementation it may not be true for arch specific implementations. One way to solve this is to always take runqueues in cpu id order. To do this we add a cpu variable to the runqueue and check it in the double runqueue locking functions. Signed-off-by:Anton Blanchard <anton@samba.org> Acked-by:

Remove the assumption that driver_register() returns the number of devices bound to the driver. In fact, it returns zero for success or a negative error value. All callers of macio_register_driver() either ignore the return value or return it as the return value of a module_init() function. Signed-off-by:

[patch 4/6] s390: qeth :allow setting of attribute "route6" to "no_router". From: Ursula Braun <braunu@de.ibm.com> when setting route6 attribute back to no_router qeth does not issue an IP ASSIST command to reset router value to no_router. Once primary_router is set device stays in this mode. Issue an IP ASSIST command when no_router is set in route6. Device will be reset and thus will not longer run as a primary router. Signed-off-by:

With Au1xx0 Ethernet driver, TX bytes/packets always remain zero. The problem seems to be that when packet has been transmitted, the length word in DMA buffer is zero.

The current code follows the spec but uses an overlong delay. This would be great if the hardware did. Several vendors however forget the D7 pulldown. Fortunately 0xFF isnt a sane reset state so we can use it to skip detection as is done in drivers/ide. (ie this is a tested solution over a long time) Signed-off-by:

The problem is in ip_push_pending_frames(), which uses: if (!df) { __ip_select_ident(iph, &rt->u.dst, 0); } else { iph->id = htons(inet->id++); } instead of ip_select_ident(). Right now I think the code is a nonsense. Most likely, I copied it from old ip_build_xmit(), where it was really special, we had to decide whether to generate unique ID when generating the first (well, the last) fragment. In ip_push_pending_frames() it does not make sense, it should use plain ip_select_ident() instead. Signed-off-by:Alexey Kuznetsov <kuznet@ms2.inr.ac.ru> Signed-off-by:
