2017-08-22arm64: hugetlb: Spring clean huge pte accessorsSteve Capper
This patch aims to re-structure the huge pte accessors without affecting their functionality. Control flow is changed to reduce indentation and expanded use is made of post for loop variable modification. It is then much easier to add break-before-make semantics in a subsequent patch.

2017-08-22arm64: hugetlb: set_huge_pte_at Add WARN_ON on !pte_presentSteve Capper
This patch adds a WARN_ON to set_huge_pte_at as the accessor assumes that entries to be written down are all present. (There are separate accessors to clear huge ptes). We will need to handle the !pte_present case where memory offlining is used on hugetlb pages. swap and migration entries will be supplied to set_huge_pte_at in this case.

(PDT) This patch adds full support to read PDT info on all machine types. At bootup the PDT is read and bad memory excluded from usage via memblock_reserve(). Later in the boot process a kernel thread is started (kpdtd) which regularily checks firmare for new reported bad memory and tries to soft offline pages in case of correctable errors and to kill processes and exclude such memory in case of uncorrectable errors via memory_failure().

2017-08-21arm64: kexec: have own crash_smp_send_stop() for crash dump for nonpanic coresHoeun Ryu
Commit 0ee5941 : (x86/panic: replace smp_send_stop() with kdump friendly version in panic path) introduced crash_smp_send_stop() which is a weak function and can be overridden by architecture codes to fix the side effect caused by commit f06e515 : (kernel/panic.c: add "crash_kexec_post_ notifiers" option). ARM64 architecture uses the weak version function and the problem is that the weak function simply calls smp_send_stop() which makes other CPUs offline and takes away the chance to save crash information for nonpanic CPUs in machine_crash_shutdown() when crash_kexec_post_notifiers kernel option is enabled. Calling smp_send_crash_stop() in machine_crash_shutdown() is useless because all nonpanic CPUs are already offline by smp_send_stop() in this case and smp_send_crash_stop() only works against online CPUs. The result is that secondary CPUs registers are not saved by crash_save_cpu() and the vmcore file misreports these CPUs as being offline. crash_smp_send_stop() is implemented to fix this problem by replacing the existing smp_send_crash_stop() and adding a check for multiple calling to the function. The function (strong symbol version) saves crash information for nonpanic CPUs and machine_crash_shutdown() tries to save crash information for nonpanic CPUs only when crash_kexec_post_notifiers kernel option is disabled. * crash_kexec_post_notifiers : false panic() __crash_kexec() machine_crash_shutdown() crash_smp_send_stop() <= save crash dump for nonpanic cores * crash_kexec_post_notifiers : true panic() crash_smp_send_stop() <= save crash dump for nonpanic cores __crash_kexec() machine_crash_shutdown() crash_smp_send_stop() <= just return.

2017-08-21KVM: s390: sthyi: fix specification exception detectionHeiko Carstens
sthyi should only generate a specification exception if the function code is zero and the response buffer is not on a 4k boundary. The current code would also test for unknown function codes if the response buffer, that is currently only defined for function code 0, is not on a 4k boundary and incorrectly inject a specification exception instead of returning with condition code 3 and return code 4 (unsupported function code). Fix this by moving the boundary check.

The sthyi inline assembly misses register r3 within the clobber list. The sthyi instruction will always write a return code to register "R2+1", which in this case would be r3. Due to that we may have register corruption and see host crashes or data corruption depending on how gcc decided to allocate and use registers during compile time.

2017-08-21arm64: zynqmp: Add generic compatible string for I2C EEPROMJavier Martinez Canillas
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.
