2018-03-23irqchip/gic-v3: Ensure GICR_CTLR.EnableLPI=0 is observed before enablingShanker Donthineni
Booting with GICR_CTLR.EnableLPI=1 is usually a bad idea, and may result in subtle memory corruption. Detecting this is thus pretty important. On detecting that LPIs are still enabled, we taint the kernel (because we're not sure of anything anymore), and try to disable LPIs. This can fail, as implementations are allowed to implement GICR_CTLR.EnableLPI as a one-way enable, meaning the redistributors cannot be reprogrammed with new tables. Should this happen, we fail probing the redistributor and warn the user that things are pretty dire.

2018-03-23tpm: fix intermittent failure with self testsJames Bottomley
My Nuvoton 6xx in a Dell XPS-13 has been intermittently failing to work (necessitating a reboot). The problem seems to be that the TPM gets into a state where the partial self-test doesn't return TPM_RC_SUCCESS (meaning all tests have run to completion), but instead returns TPM_RC_TESTING (meaning some tests are still running in the background). There are various theories that resending the self-test command actually causes the tests to restart and thus triggers more TPM_RC_TESTING returns until the timeout is exceeded. There are several issues here: firstly being we shouldn't slow down the boot sequence waiting for the self test to complete once the TPM backgrounds them. It will actually make available all functions that have passed and if it gets a failure return TPM_RC_FAILURE to every subsequent command. So the fix is to kick off self tests once and if they return TPM_RC_TESTING log that as a backgrounded self test and continue on. In order to prevent other tpm users from seeing any TPM_RC_TESTING returns (which it might if they send a command that needs a TPM subsystem which is still under test), we loop in tpm_transmit_cmd until either a timeout or we don't get a TPM_RC_TESTING return. Finally, there have been observations of strange returns from a partial test. One Nuvoton is occasionally returning TPM_RC_COMMAND_CODE, so treat any unexpected return from a partial self test as an indication we need to run a full self test.

2018-03-23tpm: add retry logicJames Bottomley
TPM2 can return TPM2_RC_RETRY to any command and when it does we get unexpected failures inside the kernel that surprise users (this is mostly observed in the trusted key handling code). The UEFI 2.6 spec has advice on how to handle this: The firmware SHALL not return TPM2_RC_RETRY prior to the completion of the call to ExitBootServices(). Implementer’s Note: the implementation of this function should check the return value in the TPM response and, if it is TPM2_RC_RETRY, resend the command. The implementation may abort if a sufficient number of retries has been done. So we follow that advice in our tpm_transmit() code using TPM2_DURATION_SHORT as the initial wait duration and TPM2_DURATION_LONG as the maximum wait time. This should fix all the in-kernel use cases and also means that user space TSS implementations don't have to have their own retry handling.

2018-03-23tpm: self test failure should not cause suspend to failChris Chiu
The Acer Acer Veriton X4110G has a TPM device detected as: tpm_tis 00:0b: 1.2 TPM (device-id 0xFE, rev-id 71) After the first S3 suspend, the following error appears during resume: tpm tpm0: A TPM error(38) occurred continue selftest Any following S3 suspend attempts will now fail with this error: tpm tpm0: Error (38) sending savestate before suspend PM: Device 00:0b failed to suspend: error 38 Error 38 is TPM_ERR_INVALID_POSTINIT which means the TPM is not in the correct state. This indicates that the platform BIOS is not sending the usual TPM_Startup command during S3 resume. >From this point onwards, all TPM commands will fail. The same issue was previously reported on Foxconn 6150BK8MC and Sony Vaio TX3. The platform behaviour seems broken here, but we should not break suspend/resume because of this. When the unexpected TPM state is encountered, set a flag to skip the affected TPM_SaveState command on later suspends.

2018-03-23tpm: cmd_ready command can be issued only after granting localityTomas Winkler
The correct sequence is to first request locality and only after that perform cmd_ready handshake, otherwise the hardware will drop the subsequent message as from the device point of view the cmd_ready handshake wasn't performed. Symmetrically locality has to be relinquished only after going idle handshake has completed, this requires that go_idle has to poll for the completion and as well locality relinquish has to poll for completion so it is not overridden in back to back commands flow. Two wrapper functions are added (request_locality relinquish_locality) to simplify the error handling. The issue is only visible on devices that support multiple localities.

2018-03-23usb/gadget: Add an EP dispose() callback for EP lifetime trackingBenjamin Herrenschmidt
Some UDC may want to allocate endpoints dynamically, either because the HW supports an arbitrary large number or because (like the Aspeed BMC SoCs), the pool of HW endpoints is shared between multiple gadgets. The allocation side can be done rather easily using the existing match_ep() UDC hook. However we have no good place to "free" them. This implements a "simple" variant of this, which calls an EP dispose callback on all EPs associated with a gadget when the composite device gets unbound.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm fixes from Dan Williams: "Two regression fixes, two bug fixes for older issues, two fixes for new functionality added this cycle that have userspace ABI concerns, and a small cleanup. These have appeared in a linux-next release and have a build success report from the 0day robot. * The 4.16 rework of altmap handling led to some configurations leaking page table allocations due to freeing from the altmap reservation rather than the page allocator. The impact without the fix is leaked memory and a WARN() message when tearing down libnvdimm namespaces. The rework also missed a place where error handling code needed to be removed that can lead to a crash if devm_memremap_pages() fails. * acpi_map_pxm_to_node() had a latent bug whereby it could misidentify the closest online node to a given proximity domain. * Block integrity handling was reworked several kernels back to allow calling add_disk() after setting up the integrity profile. The nd_btt and nd_blk drivers are just now catching up to fix automatic partition detection at driver load time. * The new peristence_domain attribute, a platform indicator of whether cpu caches are powerfail protected for example, is meant to be a single value enum and not a set of flags. This oversight was caught while reviewing new userspace code in libndctl to communicate the attribute. Fix this new enabling up so that we are not stuck with an unwanted userspace ABI" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: libnvdimm, nfit: fix persistence domain reporting libnvdimm, region: hide persistence_domain when unknown acpi, numa: fix pxm to online numa node associations x86, memremap: fix altmap accounting at free libnvdimm: remove redundant assignment to pointer 'dev' libnvdimm, {btt, blk}: do integrity setup before add_disk() kernel/memremap: Remove stale devres_free() call
