patch "iio: mma8452: Fix ignoring MMA8452_INT_DRDY" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: mma8452: Fix ignoring MMA8452_INT_DRDY to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From b02ec67a8e38875cdc5f9214be885022f11c0017 Mon Sep 17 00:00:00 2001 From: Leonard Crestez <leonard.crestez(a)nxp.com> Date: Thu, 7 Jun 2018 21:52:50 +0300 Subject: iio: mma8452: Fix ignoring MMA8452_INT_DRDY Interrupts are ignored if no event bit is set in the status status register and this breaks the buffer interface. No data is shown when running "iio_generic_buffer -n mma8451 -a" and interrupt counts go crazy. Fix by not returning IRQ_NONE if DRDY is set.

[PATCH v6] tpm: separate cmd_ready/go_idle from runtime_pm

by Tomas Winkler

We cannot use go_idle cmd_ready commands via runtime_pm handles as with the introduction of localities this is no longer an optional feature, while runtime pm can be not enabled. Though cmd_ready/go_idle provides a power saving, it's also a part of TPM2 protocol and should be called explicitly. This patch exposes cmd_read/go_idle via tpm class ops and removes runtime pm support as it is not used by any driver. A new tpm transmit flag is added TPM_TRANSMIT_NESTED, which implies TPM_TRANSMIT_UNLOCKED and TPM_TRANSMIT_RAW. Both are needed to resolve tpm spaces and locality request recursive calls to tpm_transmit(). New wrappers are added tpm_cmd_ready() and tpm_go_idle() to streamline tpm_try_transmit code. tpm_crb no longer needs own power saving functions and can drop using tpm_pm_suspend/resume. This patch cannot be really separated from the locality fix. Fixes: 888d867df441 (tpm: cmd_ready command can be issued only after granting locality) Cc: stable(a)vger.kernel.org Fixes: 888d867df441 (tpm: cmd_ready command can be issued only after granting locality) Signed-off-by: Tomas Winkler <tomas.winkler(a)intel.com> --- V2-3:resent V4: 1. Use tpm_pm_suspend/resume in tpm_crb 2. Drop cmd_ready/go_idle around tpm_chip_register, as there is no usage counter like in runtime_pm. V5: 1. add tpm_cmd_ready and tpm_go_idle wrappers. 2. Abuse TPM_TRANSMIT_UNLOCKED flag to resolve tpm space recursion. V6: 1. Add new flags TPM_TRANSMIT_NESTED which implies TPM_TRANSMIT_UNLOCKED and TPM_TRANSMIT_RAW, as not all unlocked flows are recursive i.e. tpm2_unseal_trusted. drivers/char/tpm/tpm-interface.c | 51 +++++++++++++++---- drivers/char/tpm/tpm.h | 13 ++++- drivers/char/tpm/tpm2-space.c | 12 ++--- drivers/char/tpm/tpm_crb.c | 101 ++++++++++---------------------------- drivers/char/tpm/tpm_vtpm_proxy.c | 2 +- include/linux/tpm.h | 2 + 6 files changed, 88 insertions(+), 93 deletions(-) diff --git a/drivers/char/tpm/tpm-interface.c b/drivers/char/tpm/tpm-interface.c index e32f6e85dc6d..1abd8261651b 100644 --- a/drivers/char/tpm/tpm-interface.c +++ b/drivers/char/tpm/tpm-interface.c @@ -29,7 +29,6 @@ #include <linux/mutex.h> #include <linux/spinlock.h> #include <linux/freezer.h> -#include <linux/pm_runtime.h> #include <linux/tpm_eventlog.h> #include "tpm.h" @@ -369,10 +368,13 @@ static int tpm_validate_command(struct tpm_chip *chip, return -EINVAL; } -static int tpm_request_locality(struct tpm_chip *chip) +static int tpm_request_locality(struct tpm_chip *chip, unsigned int flags) { int rc; + if (flags & __TPM_TRANSMIT_RAW) + return 0; + if (!chip->ops->request_locality) return 0; @@ -385,10 +387,13 @@ static int tpm_request_locality(struct tpm_chip *chip) return 0; } -static void tpm_relinquish_locality(struct tpm_chip *chip) +static void tpm_relinquish_locality(struct tpm_chip *chip, unsigned int flags) { int rc; + if (flags & __TPM_TRANSMIT_RAW) + return; + if (!chip->ops->relinquish_locality) return; @@ -399,6 +404,28 @@ static void tpm_relinquish_locality(struct tpm_chip *chip) chip->locality = -1; } +static int tpm_cmd_ready(struct tpm_chip *chip, unsigned int flags) +{ + if (flags & __TPM_TRANSMIT_RAW) + return 0; + + if (!chip->ops->cmd_ready) + return 0; + + return chip->ops->cmd_ready(chip); +} + +static int tpm_go_idle(struct tpm_chip *chip, unsigned int flags) +{ + if (flags & __TPM_TRANSMIT_RAW) + return 0; + + if (!chip->ops->go_idle) + return 0; + + return chip->ops->go_idle(chip); +} + static ssize_t tpm_try_transmit(struct tpm_chip *chip, struct tpm_space *space, u8 *buf, size_t bufsiz, @@ -449,14 +476,15 @@ static ssize_t tpm_try_transmit(struct tpm_chip *chip, /* Store the decision as chip->locality will be changed. */ need_locality = chip->locality == -1; - if (!(flags & TPM_TRANSMIT_RAW) && need_locality) { - rc = tpm_request_locality(chip); + if (need_locality) { + rc = tpm_request_locality(chip, flags); if (rc < 0) goto out_no_locality; } - if (chip->dev.parent) - pm_runtime_get_sync(chip->dev.parent); + rc = tpm_cmd_ready(chip, flags); + if (rc) + goto out; rc = tpm2_prepare_space(chip, space, ordinal, buf); if (rc) @@ -516,13 +544,16 @@ static ssize_t tpm_try_transmit(struct tpm_chip *chip, } rc = tpm2_commit_space(chip, space, ordinal, buf, &len); + if (rc) + dev_err(&chip->dev, "tpm2_commit_space: error %d\n", rc); out: - if (chip->dev.parent) - pm_runtime_put_sync(chip->dev.parent); + rc = tpm_go_idle(chip, flags); + if (rc) + goto out; if (need_locality) - tpm_relinquish_locality(chip); + tpm_relinquish_locality(chip, flags); out_no_locality: if (chip->ops->clk_enable != NULL) diff --git a/drivers/char/tpm/tpm.h b/drivers/char/tpm/tpm.h index 4426649e431c..beb0a763016c 100644 --- a/drivers/char/tpm/tpm.h +++ b/drivers/char/tpm/tpm.h @@ -511,9 +511,18 @@ extern const struct file_operations tpm_fops; extern const struct file_operations tpmrm_fops; extern struct idr dev_nums_idr; +/** + * enum tpm_transmit_flags + * + * @TPM_TRANSMIT_UNLOCKED: used to lock sequence of tpm_transmit calls. + * @__TPM_TRANSMIT_RAW: prevent recursive calls into setup steps + * (go idle, locality,..).

[PATCH v3 03/17] arm64: dts: marvell: fix CP110 ICU node size

[PATCH] Revert "mm: page_alloc: skip over regions of invalid pfns where possible"

by Daniel Vacek

This reverts commit b92df1de5d289c0b5d653e72414bf0850b8511e0. The commit is meant to be a boot init speed up skipping the loop in memmap_init_zone() for invalid pfns. But given some specific memory mapping on x86_64 (or more generally theoretically anywhere but on arm with CONFIG_HAVE_ARCH_PFN_VALID) the implementation also skips valid pfns which is plain wrong and causes 'kernel BUG at mm/page_alloc.c:1389!' crash> log | grep -e BUG -e RIP -e Call.Trace -e move_freepages_block -e rmqueue -e freelist -A1 kernel BUG at mm/page_alloc.c:1389!
