2017-06-06i40e: Fix state flags for bit set and clean operations of PFMauro S. M. Rodrigues1-18/+18
Commit 0da36b9774cc ("i40e: use DECLARE_BITMAP for state fields") introduced changes in the way i40e works with state flags converting them to bitmaps using kernel bitmap API. This change introduced a regression due to a mistaken substitution using __I40E_VSI_DOWN instead of __I40E_DOWN when testing state of a PF at i40e_reset_subtask() function. This caused a flood in the kernel log with the follow message: [49.013] i40e 0002:01:00.0: bad reset request 0x00000020 Commit d19cb64b9222 ("i40e: separate PF and VSI state flags") also introduced some misuse of the VSI and PF flags, so both could be considered as the offenders. This patch simply fixes the flags where it makes sense by changing __I40E_VSI_DOWN to __I40E_DOWN.

2017-06-05iwlwifi: mvm: fix firmware debug restart recordingEmmanuel Grumbach4-19/+27
When we want to stop the recording of the firmware debug and restart it later without reloading the firmware we don't need to resend the configuration that comes with host commands. Sending those commands confused the hardware and led to an NMI 0x66. Change the flow as following: * read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL) * clear those registers * wait for the hardware to complete its write to the buffer * get the data * restore the value of those registers (to restart the recording) For early start (where the configuration is already compiled in the firmware), we don't need to set those registers after the firmware has been loaded, but only when we want to restart the recording without having restarted the firmware.

2017-06-05iwlwifi: mvm: rs: start using LQ command colorGregory Greenman6-36/+47
Up until now, the driver was comparing the rate reported by the FW and the rate of the latest LQ command to avoid processing data belonging to the old LQ command. Recently, FW changed the meaning of the initial rate field in tx response and it holds the actual rate (which is not necessarily the initial rate of LQ's rate table). Use instead LQ cmd color to be able to filter out tx responses/BA notifications which where sent during earlier LQ commands' time frame. This fixes some throughput degradation in noisy environments.

2017-06-05ARM: 8677/1: boot/compressed: fix decompressor header layout for v7-MArd Biesheuvel2-10/+11
As reported by Patrice, the header layout of the decompressor is incorrect when building for v7-M. In this case, the __nop macro resolves to 'mov r0, r0', which is emitted as a narrow encoding, resulting in the header data fields to end up at lower offsets than required. Given the variety of targets we need to support with the same code, the startup sequence is a bit of a jumble, and uses instructions and macros whose encoding widths cannot be specified (badr), or only exist in a narrow encoding (bx) So force the use of a wide encoding in __nop, and replace the start sequence with a simple jump to the label marking the start of code, preceded by a Thumb2 mode switch if required (using explicit wide encodings where appropriate). The label itself can be moved to the start of code [where it belongs] due to the larger range of branch instructions as compared to adr instructions.

2017-06-04net: dsa: Fix stale cpu_switch reference after unbind then bindFlorian Fainelli1-1/+3
Commit 9520ed8fb841 ("net: dsa: use cpu_switch instead of ds[0]") replaced the use of dst->ds[0] with dst->cpu_switch since that is functionally equivalent, however, we can now run into an use after free scenario after unbinding then rebinding the switch driver. The use after free happens because we do correctly initialize dst->cpu_switch the first time we probe in dsa_cpu_parse(), then we unbind the driver: dsa_dst_unapply() is called, and we rebind again. dst->cpu_switch now points to a freed "ds" structure, and so when we finally dereference it in dsa_cpu_port_ethtool_setup(), we oops. To fix this, simply set dst->cpu_switch to NULL in dsa_dst_unapply() which guarantees that we always correctly re-assign dst->cpu_switch in dsa_cpu_parse().

This fixes a problem with reading files larger than 2GB from a UFS-2 file system: https://bugzilla.kernel.org/show_bug.cgi?id=195721 The incorrect UFS s_maxsize limit became a problem as of commit c2a9737f45e2 ("vfs,mm: fix a dead loop in truncate_inode_pages_range()") which started using s_maxbytes to avoid a page index overflow in do_generic_file_read(). That caused files to be truncated on UFS-2 file systems because the default maximum file size is 2GB (MAX_NON_LFS) and UFS didn't update it.

2017-06-04net: qcom/emac: do not use hardware mdio automatic pollingTimur Tabi3-93/+6
Use software polling (PHY_POLL) to check for link state changes instead of relying on the EMAC's hardware polling feature. Some PHY drivers are unable to get a functioning link because the HW polling is not robust enough. The EMAC is able to poll the PHY on the MDIO bus looking for link state changes (via the Link Status bit in the Status Register at address 0x1). When the link state changes, the EMAC triggers an interrupt and tells the driver what the new state is. The feature eliminates the need for software to poll the MDIO bus. Unfortunately, this feature is incompatible with phylib, because it ignores everything that the PHY core and PHY drivers are trying to do. In particular: 1. It assumes a compatible register set, so PHYs with different registers may not work. 2. It doesn't allow for hardware errata that have work-arounds implemented in the PHY driver. 3. It doesn't support multiple register pages. If the PHY core switches the register set to another page, the EMAC won't know the page has changed and will still attempt to read the same PHY register. 4. It only checks the copper side of the link, not the SGMII side. Some PHY drivers (e.g. at803x) may also check the SGMII side, and report the link as not ready during autonegotiation if the SGMII link is still down. Phylib then waits for another interrupt to query the PHY again, but the EMAC won't send another interrupt because it thinks the link is up.

exit_loop is not being initialized, so it contains garbage. Ensure it is initialized to false.

2017-06-04[media] atomisp: don't treat warnings as errorsMauro Carvalho Chehab4-7/+1
Several atomisp files use: ccflags-y += -Werror As, on media, our usual procedure is to use W=1, and atomisp has *a lot* of warnings with such flag enabled,like: ./drivers/staging/media/atomisp/pci/atomisp2/css2400/hive_isp_css_common/host/system_local.h:62:26: warning: 'DDR_BASE' defined but not used [-Wunused-const-variable=] At the end, it causes our build to fail, impacting our workflow. So, remove this crap. If one wants to force -Werror, he can still build with it enabled by passing a parameter to make. Signed-off-by: Mauro Carvalho Chehab <[email protected]>

2017-06-03nfs: Mark unnecessarily extern functions as staticJan Kara2-4/+3
nfs_initialise_sb() and nfs_clone_super() are declared as extern even though they are used only in fs/nfs/super.c. Mark them as static. Also remove explicit 'inline' directive from nfs_initialise_sb() and leave it upto compiler to decide whether inlining is worth it.
