Merge "SOCFPGA fixes for 3.18" from Dinh Nguyen: These patches fixes an SMP and SDMMC driver hang during boot up on the SOCFPGA platform. Patch "arm: socfpga: fix fetching cpu1start_addr for SMP" fixes the SMP trampoline code in order for CPU1 to correctly fetch it's cpu1start_addr. Patch "ARM: dts: socfpga: rename gpio nodes" renames that GPIO node in order to allow a standard way of specifying status="okay" in the board DTS file. Patch "ARM: dts: socfpga: Fix SD card detect" fixes a SDMMC driver hang during boot. The reason for the hang was the deferred probe of the SDMMC driver was waiting for the GPIO resource that would never come. Patch "ARM: dts: socfpga: Add a 3.3V fixed regulator node" adds a fixed regulator node for the SDMMC driver to use. * tag 'socfpga_fixes_for_3.18' of git://git.rocketboards.org/linux-socfpga-next: ARM: dts: socfpga: Add a 3.3V fixed regulator node ARM: dts: socfpga: Fix SD card detect ARM: dts: socfpga: rename gpio nodes arm: socfpga: fix fetching cpu1start_addr for SMP Signed-off-by: NOlof Johansson <olof@lixom.net>

Without this patch, the booting the SOCFPGA platform would hang at the SDMMC driver loading. The issue, debugged by Doug Anderson, turned out to be that the GPIO bank used by the SD card-detect was not set to status="okay". Also update the cd-gpios to point to portb of the &gpio1 GPIO IP.

Since the Synopsys GPIO IP can support multiple ports of varying widths, it would make more sense to have the GPIO node DTS entry as this: gpio0: gpio@ff708000{ porta{ }; }; Also, this is documented in the snps-dwapb-gpio.txt.

When CPU1 is brought out of reset, it's MMU is not turned on yet, so it will only be able to use physical addresses. For systems with that have the MMU page configured for 0xC0000000, 0x80000000, or 0x40000000 "BIC 0x40000000" will work just fine, as it was just converting the virtual address of &cpu1start_addr into a physical address, ie. 0xC0000000 became 0x80000000. So for systems where the SDRAM controller was able to do a wrap-around access, this was working fine, as it was just dropping the MSB, but for systems where out of bounds memory access is not allowed, this would not allow CPU1 to correctly fetch &cpu1start_addr. This patch fixes the secondary_trampoline code to correctly fetch the physical address of cpu1start_addr directly. The patch will subtract the correct PAGE_OFFSET from &cpu1start_addr. And since on this platform, the physical memory will always start at 0x0, subtracting PAGE_OFFSET from &cpu1start_addr will allow CPU1 to correctly fetch the value of cpu1start_addr. While at it, change the name of cpu1start_addr to socfpga_cpu1start_addr to avoid any future naming collisions for multiplatform image. Signed-off-by: NDinh Nguyen <dinguyen@opensource.altera.com> --- v4: Updated commit log to correctly lay out the usage of PAGE_OFFSET and add comments to the same effect. v3: Used PAGE_OFFSET to get the physical address v2: Correctly get the physical address instead of just a BIC hack.

Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs.

This breaks the stack end corruption detection facility. What that facility does it write a magic value to "end_of_stack()" and checking to see if it gets overwritten. "end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is the beginning of the FPU register save area. So once the user uses the FPU, the magic value is overwritten and the debug checks trigger. Fix this by making the size explicit. Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we are limited to 7 levels of FPU state saves. So each FPU register set is 256 bytes, allocate 256 * 7 for the fpregs area.

Every path that ends up at do_sparc64_fault() must install a valid FAULT_CODE_* bitmask in the per-thread fault code byte. Two paths leading to the label winfix_trampoline (which expects the FAULT_CODE_* mask in register %g4) were not doing so: 1) For pre-hypervisor TLB protection violation traps, if we took the 'winfix_trampoline' path we wouldn't have %g4 initialized with the FAULT_CODE_* value yet. Resulting in using the TLB_TAG_ACCESS register address value instead. 2) In the TSB miss path, when we notice that we are going to use a hugepage mapping, but we haven't allocated the hugepage TSB yet, we still have to take the window fixup case into consideration and in that particular path we leave %g4 not setup properly. Errors on this sort were largely invisible previously, but after commit 4ccb9272 ("sparc64: sun4v TLB error power off events") we now have a fault_code mask bit (FAULT_CODE_BAD_RA) that triggers due to this bug. FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS (see #1 above) and thus we get seemingly random bus errors triggered for user processes.
