2018-04-16clk: meson: honor CLK_MUX_ROUND_CLOSEST in clk_regmapJerome Brunet
Using __clk_mux_determine_rate effectively ignores CLK_MUX_ROUND_CLOSEST if set the related clk_regmap mux instance. Use clk_mux_determine_rate_flags() to make sure the flag is honored.

2018-04-16clk: honor CLK_MUX_ROUND_CLOSEST in generic clk muxJerome Brunet
CLK_MUX_ROUND_CLOSEST is part of the clk_mux documentation but clk_mux directly calls __clk_mux_determine_rate(), which overrides the flag. As result, if clk_mux is instantiated with CLK_MUX_ROUND_CLOSEST, the flag will be ignored and the clock rounded down. To solve this, this patch expose clk_mux_determine_rate_flags() in the clk-provider API and uses it in the determine_rate() callback of clk_mux.

2018-04-16netfilter: nf_tables: can't fail after linking rule into active rule listFlorian Westphal
rules in nftables a free'd using kfree, but protected by rcu, i.e. we must wait for a grace period to elapse. Normal removal patch does this, but nf_tables_newrule() doesn't obey this rule during error handling. It calls nft_trans_rule_add() *after* linking rule, and, if that fails to allocate memory, it unlinks the rule and then kfree() it -- this is unsafe. Switch order -- first add rule to transaction list, THEN link it to public list. Note: nft_trans_rule_add() uses GFP_KERNEL; it will not fail so this is not a problem in practice (spotted only during code review).

2018-04-16netfilter: fix CONFIG_NF_REJECT_IPV6=m link errorArnd Bergmann
We get a new link error with CONFIG_NFT_REJECT_INET=y and CONFIG_NF_REJECT_IPV6=m after larger parts of the nftables modules are linked together: net/netfilter/nft_reject_inet.o: In function `nft_reject_inet_eval': nft_reject_inet.c:(.text+0x17c): undefined reference to `nf_send_unreach6' nft_reject_inet.c:(.text+0x190): undefined reference to `nf_send_reset6' The problem is that with NF_TABLES_INET set, we implicitly try to use the ipv6 version as well for NFT_REJECT, but when CONFIG_IPV6 is set to a loadable module, it's impossible to reach that. The best workaround I found is to express the above as a Kconfig dependency, forcing NFT_REJECT itself to be 'm' in that particular configuration.

2018-04-16ibmvnic: Clear pending interrupt after device resetThomas Falcon
Due to a firmware bug, the hypervisor can send an interrupt to a transmit or receive queue just prior to a partition migration, not allowing the device enough time to handle it and send an EOI. When the partition migrates, the interrupt is lost but an "EOI-pending" flag for the interrupt line is still set in firmware. No further interrupts will be sent until that flag is cleared, effectively freezing that queue. To workaround this, the driver will disable the hardware interrupt and send an H_EOI signal prior to re-enabling it. This will flush the pending EOI and allow the driver to continue operation.

The new support for the standard _LSR and _LSW methods neglected to also update the nvdimm_init_config_data() and nvdimm_set_config_data() to return the translated error code from failed commands. This precision is necessary because the locked status that was previously returned on ND_CMD_GET_CONFIG_SIZE commands is now returned on ND_CMD_{GET,SET}_CONFIG_DATA commands.

2018-04-17powerpc/lib: Fix off-by-one in alternate feature patchingMichael Ellerman
When we patch an alternate feature section, we have to adjust any relative branches that branch out of the alternate section. But currently we have a bug if we have a branch that points to past the last instruction of the alternate section, eg: FTR_SECTION_ELSE 1: b 2f or 6,6,6 2: ALT_FTR_SECTION_END(...) nop This will result in a relative branch at 1 with a target that equals the end of the alternate section. That branch does not need adjusting when it's moved to the non-else location. Currently we do adjust it, resulting in a branch that goes off into the link-time location of the else section, which is junk. The fix is to not patch branches that have a target == end of the alternate section.

2018-04-16xen: xen-pciback: Replace GFP_ATOMIC with GFP_KERNEL in pcistub_reg_addJia-Ju Bai
pcistub_reg_add() is never called in atomic context. pcistub_reg_add() is only called by pcistub_quirk_add, which is only set in DRIVER_ATTR(). Despite never getting called from atomic context, pcistub_reg_add() calls kzalloc() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it.

2018-04-16net: mvpp2: Fix TCAM filter reserved rangeMaxime Chevallier
Marvell's PPv2 controller has a Packet Header parser, which uses a fixed-size TCAM array of filter entries. The mvpp2 driver reserves some ranges among the 256 TCAM entries to perform MAC and VID filtering. The rest of the TCAM ids are freely usable for other features, such as IPv4 proto matching. This commit fixes the MVPP2_PE_LAST_FREE_TID define that sets the end of the "free range", which included the MAC range. This could therefore allow some other features to use entries dedicated to MAC filtering, lowering the number of unicast/multicast addresses that could be allowed before switching to promiscuous mode.
