[PATCH v4] f_midi_complete to call queue_work

by Jill Donahue

From: Jill Donahue <jilliandonahue58(a)gmail.com> When using USB MIDI, a lock is attempted to be acquired twice through a re-entrant call to f_midi_transmit, causing a deadlock. Fix it by using queue_work() to schedule the inner f_midi_transmit() via a high priority work queue from the completion handler.

[PATCH v3 0/3] alpha: stack fixes

by Ivan Kokshaysky

This series fixes oopses on Alpha/SMP observed since kernel v6.9. [1] Thanks to Magnus Lindholm for identifying that remarkably longstanding bug. The problem is that GCC expects 16-byte alignment of the incoming stack since early 2004, as Maciej found out [2]: Having actually dug speculatively I can see that the psABI was changed in GCC 3.5 with commit e5e10fb4a350 ("re PR target/14539 (128-bit long double improperly aligned)") back in Mar 2004, when the stack pointer alignment was increased from 8 bytes to 16 bytes, and arch/alpha/kernel/entry.S has various suspicious stack pointer adjustments, starting with SP_OFF which is not a whole multiple of 16. Also, as Magnus noted, "ALPHA Calling Standard" [3] required the same: D.3.1 Stack Alignment This standard requires that stacks be octaword aligned at the time a new procedure is invoked. However: - the "normal" kernel stack is always misaligned by 8 bytes, thanks to the odd number of 64-bit words in 'struct pt_regs', which is the very first thing pushed onto the kernel thread stack; - syscall, fault, interrupt etc. handlers may, or may not, receive aligned stack depending on numerous factors. Somehow we got away with it until recently, when we ended up with a stack corruption in kernel/smp.c:smp_call_function_single() due to its use of 32-byte aligned local data and the compiler doing clever things allocating it on the stack. Patche 1 is preparatory; 2 - the main fix; 3 - fixes remaining special cases. Ivan.

[PATCH] cifs: pick channels for individual subrequests

by nspmangalore＠gmail.com

From: Shyam Prasad N <sprasad(a)microsoft.com> The netfs library could break down a read request into multiple subrequests. When multichannel is used, there is potential to improve performance when each of these subrequests pick a different channel. Today we call cifs_pick_channel when the main read request is initialized in cifs_init_request. This change moves this to cifs_prepare_read, which is the right place to pick channel since it gets called for each subrequest. Interestingly cifs_prepare_write already does channel selection for individual subreq, but looks like it was missed for read. This is especially important when multichannel is used with increased rasize. In my test setup, with rasize set to 8MB, a sequential read of large file was taking 11.5s without this change. With the change, it completed in 9s. The difference is even more signigicant with bigger rasize.

[PATCH 2/3] perf/x86/intel: Fix ARCH_PERFMON_NUM_COUNTER_LEAF

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> The EAX of the CPUID Leaf 023H enumerates the mask of valid sub-leaves. To tell the availability of the sub-leaf 1 (enumerate the counter mask), perf should check the bit 1 (0x2) of EAS, rather than bit 0 (0x1). The error is not user-visible on bare metal. Because the sub-leaf 0 and the sub-leaf 1 are always available. However, it may bring issues in a virtualization environment when a VMM only enumerates the sub-leaf 0. Introduce the cpuid35_e?x to replace the macros, which makes the implementation style consistent.
