Instead a Kconfig confusion that I think I have finally nailed, then some ordinary driver noise and trivia. This fixes a Kconfig issue with UM: when I made GPIOLIB available to all archs, that included UM, but the OF part of GPIOLIB requires HAS_IOMEM, so we add HAS_IOMEM as a dependency to OF_GPIO. This in turn exposed the fact that a few GPIO drivers were implicitly assuming OF_GPIO as their dependency but instead depended on OF alone (the typical problem being a pointer inside gpio_chip not existing unless OF_GPIO is selected) and then UM would fail to compile with these drivers instead. Then I lost patience and made any GPIO driver depending on just OF depend on OF_GPIO instead, that is certainly what they meant and the only thing that makes sense anyway. GPIO with just OF but !OF_GPIO does not make sense.

This is an entirely new driver instead of yet another set of patches to sb_edac.c because: 1) Mapping from PCI devices to socket/memory controller is significantly different. Skylake scatters devices on a socket across a number of PCI buses. 2) There is an extra level of interleaving via the "mcroute" register that would be a little messy to squeeze into the old driver. 3) Validation is getting too expensive. Changes to sb_edac need to be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and Knights Landing.

When building gccgo in userspace, errno.h gets parsed and the go include file sysinfo.go is generated. Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED is defined later on in errno.h, this leads to go complaining that EREFUSED isn't defined yet. Fix this trivial problem by moving the define of EREFUSED down after ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

The kernel test robot reported a usercopy failure in the new hardened sanity checks, due to a page-crossing copy of the FPU state into the task structure. This happened because the kernel test robot was testing with SLOB, which doesn't actually do the required book-keeping for slab allocations, and as a result the hardening code didn't realize that the task struct allocation was one single allocation - and the sanity checks fail. Since SLOB doesn't even claim to support hardening (and you really shouldn't use it), the straightforward solution is to just make the usercopy hardening code depend on the allocator supporting it.

The syscall ABI includes the gcc functional calling ABI since a syscall implies userland caller and kernel callee. The current gcc ABI (v3) for ARCv2 ISA required 64-bit data be passed in even-odd register pairs, (potentially punching reg holes when passing such values as args). This was partly driven by the fact that the double-word LDD/STD instructions in ARCv2 expect the register alignment and thus gcc forcing this avoids extra MOV at the cost of a few unused register (which we have plenty anyways). This however was rejected as part of upstreaming gcc port to HS. So the new ABI v4 doesn't enforce the even-odd reg restriction. Do note that for ARCompact ISA builds v3 and v4 are practically the same in terms of gcc code generation. In terms of change management, we infer the new ABI if gcc 6.x onwards is used for building the kernel. This also needs a stable backport to enable older kernels to work with new tools/user-space Cc: <stable@vger.kernel.org> Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

User mode callee regs are explicitly collected before signal delivery or breakpoint trap. r25 is special for kernel as it serves as task pointer, so user mode value is clobbered very early. It is saved in pt_regs where generally only scratch (aka caller saved) regs are saved. The code to access the corresponding pt_regs location had a subtle bug as it was using load/store with scaling of offset, whereas the offset was already byte wise correct. So fix this by replacing LD.AS with a standard LD Cc: <stable@vger.kernel.org> Signed-off-by: NLiav Rehana <liavr@mellanox.com> Reviewed-by: NAlexey Brodkin <abrodkin@synopsys.com> [vgupta: rewrote title and commit log] Signed-off-by: NVineet Gupta <vgupta@synopsys.com>

The drivers that depend on OF but not OF_GPIO are wreaking havoc with the autobuilders for archs that have all requirements for OF but not for OF_GPIO, particularly the UM (Usermode) arch does not have iomem (NO_IOMEM) which result in configuring GPIOLIB but without OF_GPIO which is wrong if the driver is using the .of_node of the gpiochip, which only appears with OF_GPIO. After a brief look at the drivers just depending on OF it seems most if not all of them actually require stuff from gpiolib-of so the dependency is wrong in the first place. This simply patches the Kconfig so that all GPIO drivers using OF depend on OF_GPIO rather than just OF.

The UserMode (UM) Linux build was failing in gpiolib-of as it requires ioremap()/iounmap() to exist, which is absent from UM. The non-existence of IO memory is negatively defined as CONFIG_NO_IOMEM which means we need to depend on HAS_IOMEM.

Thread A Thread B - inode_lock fileA - inode_lock fileB - inode_lock fileA - inode_lock fileB We may encounter above potential deadlock during moving file range in concurrent scenario.
