The kbuild test robot reported this objtool warning [1]: arch/x86/kvm/emulate.o: warning: objtool: fastop()+0x69: call without frame pointer save/setup The issue seems to be caused by CONFIG_PROFILE_ALL_BRANCHES. With that option, for some reason gcc decides not to create a stack frame in fastop() before doing the inline asm call, which can result in a bad stack trace. Force a stack frame to be created if CONFIG_FRAME_POINTER is enabled by listing the stack pointer as an output operand for the inline asm statement. This change has no effect for !CONFIG_PROFILE_ALL_BRANCHES.

This reverts commit 1028b55b. It's broken: it makes ext4 return an error at an invalid point, causing the readdir wrappers to write the the position of the last successful directory entry into the position field, which means that the next readdir will now return that last successful entry _again_. You can only return fatal errors (that terminate the readdir directory walk) from within the filesystem readdir functions, the "normal" errors (that happen when the readdir buffer fills up, for example) happen in the iterorator where we know the position of the actual failing entry. I do have a very different patch that does the "signal_pending()" handling inside the iterator function where it is allowable, but while that one passes all the sanity checks, I screwed up something like four times while emailing it out, so I'm not going to commit it today. So my track record is not good enough, and the stars will have to align better before that one gets committed. And it would be good to get some review too, of course, since celestial alignments are always an iffy debugging model. IOW, let's just revert the commit that caused the problem for now.

An interrupt handler that uses the fpu can kill a KVM VM, if it runs under the following conditions: - the guest's xcr0 register is loaded on the cpu - the guest's fpu context is not loaded - the host is using eagerfpu Note that the guest's xcr0 register and fpu context are not loaded as part of the atomic world switch into "guest mode". They are loaded by KVM while the cpu is still in "host mode". Usage of the fpu in interrupt context is gated by irq_fpu_usable(). The interrupt handler will look something like this: if (irq_fpu_usable()) { kernel_fpu_begin(); [... code that uses the fpu ...] kernel_fpu_end(); } As long as the guest's fpu is not loaded and the host is using eager fpu, irq_fpu_usable() returns true (interrupted_kernel_fpu_idle() returns true). The interrupt handler proceeds to use the fpu with the guest's xcr0 live. kernel_fpu_begin() saves the current fpu context. If this uses XSAVE[OPT], it may leave the xsave area in an undesirable state. According to the SDM, during XSAVE bit i of XSTATE_BV is not modified if bit i is 0 in xcr0. So it's possible that XSTATE_BV[i] == 1 and xcr0[i] == 0 following an XSAVE. kernel_fpu_end() restores the fpu context. Now if any bit i in XSTATE_BV == 1 while xcr0[i] == 0, XRSTOR generates a #GP. The fault is trapped and SIGSEGV is delivered to the current process. Only pre-4.2 kernels appear to be vulnerable to this sequence of events. Commit 653f52c3 ("kvm,x86: load guest FPU context more eagerly") from 4.2 forces the guest's fpu to always be loaded on eagerfpu hosts. This patch fixes the bug by keeping the host's xcr0 loaded outside of the interrupts-disabled region where KVM switches into guest mode.

That limits what the library can do, and we cannot reference uninitialized fields until later. Defer some of the initialization until right after the gpiolib is initialized in these (rare) cases. - As a consequence: do not use devm_* resources when allocating the states in the initial set-up of the gpiochip.

Handling exceptions from modules never worked on parisc. It was just masked by the fact that exceptions from modules don't happen during normal use. When a module triggers an exception in get_user() we need to load the main kernel dp value before accessing the exception_data structure, and afterwards restore the original dp value of the module on exit.

The kernel module testcase (lib/test_user_copy.c) exhibited a kernel crash on parisc if the parameters for copy_from_user were reversed ("illegal reversed copy_to_user" testcase). Fix this potential crash by checking the fault handler if the faulting address is in the exception table.

We want to avoid the kernel module loader to create function pointers for the kernel fixup routines of get_user() and put_user(). Changing the external reference from function type to int type fixes this. This unbreaks exception handling for get_user() and put_user() when called from a kernel module.

Commit 0de79858 (parisc: Use generic extable search and sort routines) changed the exception tables to use 32bit relative offsets. This patch now adds support to the kernel module loader to handle such R_PARISC_PCREL32 relocations for 32- and 64-bit modules. Signed-off-by: NHelge Deller <deller@gmx.de>

After commit f84bb1ea ("net: fix IFF_NO_QUEUE for drivers using alloc_netdev"), default qdisc was changed to noqueue because tuntap does not set tx_queue_len during .setup(). This patch restores default qdisc by setting tx_queue_len in tun_setup().
