2012-10-15cfg80211/mac80211: avoid state mishmash on deauthStanislaw Gruszka
Avoid situation when we are on associate state in mac80211 and on disassociate state in cfg80211. This can results on crash during modules unload (like showed on this thread: http://marc.info/?t=134373976300001&r=1&w=2) and possibly other problems.

2012-10-15ARM: fix oops on initial entry to userspace with Thumb2 kernelsRussell King

In init/main.c, we issue: kernel_thread(kernel_init, NULL, CLONE_FS | CLONE_SIGHAND); This creates a new thread, which falls through to the ret_from_fork assembly, with r4 set NULL and r5 set to kernel_init. You can see this in your oops dump register set - r5 is 0xc0344555, which is the address of kernel_init plus 1 which marks the function as Thumb code. Now, let's look at this code a little closer - this is what the disassembly looks like: c000d180 <ret_from_fork>: c000d180: f03a fe08 bl c0047d94 <schedule_tail> c000d184: 2d00 cmp r5, #0 c000d186: bf1e ittt ne c000d188: 4620 movne r0, r4 c000d18a: 46fe movne lr, pc <-- XXXXXXX c000d18c: 46af movne pc, r5 c000d18e: 46e9 mov r9, sp c000d190: ea4f 3959 mov.w r9, r9, lsr #13 c000d194: ea4f 3949 mov.w r9, r9, lsl #13 c000d198: e7c8 b.n c000d12c <ret_to_user> c000d19a: bf00 nop c000d19c: f3af 8000 nop.w This code was introduced in 9fff2fa0db911 (arm: switch to saner kernel_execve() semantics). I have marked one instruction, and it's the significant one - I'll come back to that later. Eventually, having had a successful call to kernel_execve(), kernel_init() returns zero. In returning, it uses the value in 'lr' which was set by the instruction I marked above. Unfortunately, this causes lr to contain 0xc000d18e - an even address. This switches the ISA to ARM on return but with a non word aligned PC value. So, what do we end up executing? Well, not the instructions above - yes the opcodes, but they don't mean the same thing in ARM mode. In ARM mode, it looks like this instead: c000d18c: 46e946af strbtmi r4, [r9], pc, lsr #13 c000d190: 3959ea4f ldmdbcc r9, {r0, r1, r2, r3, r6, r9, fp, sp, lr, pc}^ c000d194: 3949ea4f stmdbcc r9, {r0, r1, r2, r3, r6, r9, fp, sp, lr, pc}^ c000d198: bf00e7c8 svclt 0x0000e7c8 c000d19c: 8000f3af andhi pc, r0, pc, lsr #7 c000d1a0: e88db092 stm sp, {r1, r4, r7, ip, sp, pc} c000d1a4: 46e81fff ; <UNDEFINED> instruction: 0x46e81fff c000d1a8: 8a00f3ef bhi 0xc004a16c c000d1ac: 0a0cf08a beq 0xc03493dc I have included more above, because it's relevant. The PSR flags which we can see in the oops dump are nZCv, so Z and C are set. All the above ARM instructions are not executed, except for two. c000d1a0, which has no writeback, and writes below the current stack pointer (and that data is lost when we take the next exception.) The other instruction which is executed is c000d1ac, which takes us to... 0xc03493dc. However, remember that bit 1 of the PC got set. So that makes the PC value 0xc03493de. And that value is the value we find in the oops dump for PC. What is the instruction here when interpreted in ARM mode? 0: f71e150c ; <UNDEFINED> instruction: 0xf71e150c and there we have our undefined instruction (remember that the 'never' condition code, 0xf, has been deprecated and is now always executed as it is now being used for additional instructions.) This path also nicely explains the state of the stack we see in the oops dump too. The above is a consistent and sane story for how we got to the oops dump, which all stems from the instruction at 0xc000d18a being wrong.

If a USB transfer has already been started, meaning we have already issued StartTransfer command to that particular endpoint, DWC3_EP_BUSY flag has also already been set. When we try to cancel this transfer which is already in controller's cache, we will not receive XferComplete event and we must clear DWC3_EP_BUSY in order to allow subsequent requests to be properly started. The best place to clear that flag is right after issuing DWC3_DEPCMD_ENDTRANSFER.

2012-10-15pinctrl/nomadik: provide stubs for legacy NomadikLinus Walleij
The compilation of the pinctrl driver failed on the legacy Nomadik NHK8815 platform because it was not providing the PRCMU interfaces needed to support the extended alternate functions used by the ux500 series. Solve this by providing some stubs for the legacy platform, to avoid too much #ifdefs in the code per se. Theoretically this actually allows the Nomadik and Ux500 to have a single kernel image with support for the PRCM registers on the Ux500 (though they have incompatible archs, but the spirit is there).

2012-10-15pinctrl: sirf: remove sirfsoc_gpio_set_pull functionArnd Bergmann
The prima2 platform advertises needing no mach/gpio.h header file, but its pinctrl driver now has a sirfsoc_gpio_set_pull function that uses constants defined in arch/arm/mach-prima2/include/mach/gpio.h, which fails to build. Fortunately, the sirfsoc_gpio_set_pull is not used anywhere in the kernel, so we can safely remove it. Any out of tree drivers using it will have to be converted to use proper pinctrl functions to do the same. Without this patch, building prima2_defconfig results in: drivers/pinctrl/pinctrl-sirf.c: In function 'sirfsoc_gpio_set_pull': drivers/pinctrl/pinctrl-sirf.c:1331:7: error: 'SIRFSOC_GPIO_PULL_NONE' undeclared (first use in this function) drivers/pinctrl/pinctrl-sirf.c:1331:7: note: each undeclared identifier is reported only once for each function it appears in drivers/pinctrl/pinctrl-sirf.c:1334:7: error: 'SIRFSOC_GPIO_PULL_UP' undeclared (first use in this function) drivers/pinctrl/pinctrl-sirf.c:1338:7: error: 'SIRFSOC_GPIO_PULL_DOWN' undeclared (first use in this function) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2012-10-14x86, boot: Explicitly include autoconf.h for hostprogsMatt Fleming
The hostprogs need access to the CONFIG_* symbols found in include/generated/autoconf.h. But commit abbf1590de22 ("UAPI: Partition the header include path sets and add uapi/ header directories") replaced $(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary include paths. This has the undesirable effect of breaking the EFI boot stub because the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is never compiled. It should also be noted that because $(USERINCLUDE) isn't exported by the top-level Makefile it's actually empty in arch/x86/boot/Makefile. Cc: H.

Pull ARM update from Russell King: "This is the final round of stuff for ARM, left until the end of the merge window to reduce the number of conflicts. This set contains the ARM part of David Howells UAPI changes, and a fix to the ordering of 'select' statements in ARM Kconfig files (see the appropriate commit for why this happened - thanks to Andrew Morton for pointing out the problem.) I've left this as long as I dare for this window to avoid conflicts, and I regenerated the config patch yesterday, posting it to our mailing list for review and testing. I have several acks which include successful test reports for it. However, today I notice we've got new conflicts with previously unseen code... though that conflict should be trivial (it's my changes vs a one liner.)" * 'late-for-linus' of git://git.linaro.org/people/rmk/linux-arm: ARM: config: make sure that platforms are ordered by option string ARM: config: sort select statements alphanumerically UAPI: (Scripted) Disintegrate arch/arm/include/asm Fix up fairly conflict in arch/arm/Kconfig (the select re-organization vs recent addition of GENERIC_KERNEL_EXECVE)

git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-linus USB 3.0 Link PM fixes. Hi Greg, Here's four fixes for the USB 3.0 Link Power Management code. They work around some USB 3.0 devices that don't support LPM, like the Western Digital My Passport hard drive. They also fix an LPM disable ref count bug that would cause LPM to remain disabled for a device after a failed probe. Please queue for 3.7 after the merge window closes. Several patches are marked for stable. Sarah Sharp

git://git.infradead.org/users/dhowells/linux-headers Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells: "The patches contained herein do the following: (1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked this with Paul Mackerras before I created the patch and he suggested some extra bits to unexport. (2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace applicable, and remove from the UAPI that part of linux/fs.h that was the reason for linux/blk_types.h being exported in the first place. I discussed this with Jens Axboe before creating the patch. (3) The big patch of the series to disintegrate include/linux/*.h as a unit. This could be split up, though there would be collisions in moving stuff between the two Kbuild files when the parts are merged as that file is sorted alphabetically rather than being grouped by subsystem. Of this set of headers, 17 files have changed in the UAPI exported region since the 4th and only 8 since the 9th so there isn't much change in this area - as one might expect. It should be pretty obvious and straightforward if it does come to fixing up: stuff in __KERNEL__ guards stays where it is and stuff outside moves to the same file in the include/uapi/linux/ directory. If a new file appears then things get a bit more complicated as the "headers +=" line has to move to include/uapi/linux/Kbuild. Only one new file has appeared since the 9th and I judge this type of event relatively unlikely. (4) A patch to disintegrate include/linux/byteorder/*.h as a unit.
