2017-12-18eeprom: at25: Add DT support for EEPROMs with odd address bitsGeert Uytterhoeven1-0/+3
Certain EEPROMS have a size that is larger than the number of address bytes would allow, and store the MSB of the address in bit 3 of the instruction byte. This can be described in platform data using EE_INSTR_BIT3_IS_ADDR, or in DT using the obsolete legacy "at25,addr-mode" property. But currently there exists no non-deprecated way to describe this in DT. Hence extend the existing "address-width" DT property to allow specifying 9 address bits, and enable support for that in the driver. This has been tested with a Microchip 25LC040A.

When mei driver is powering down due to suspend or shutdown it will iterate over the mei client bus and disconnect each client device attached in turn. The power down flow consist of the link rest, which causes all clients get disconnected at once, hence the individual disconnection can be omitted and significantly reduce power down flow.

The at24 driver creates dummy I2C devices to access offsets in the chip that are outside the area supported using a single I2C address.

There's an ilog2() expansion in AT24_DEVICE_MAGIC() which rounds down the actual size of EUI-48 byte array in at24mac402 eeproms to 4 from 6, making it impossible to read it all.

Highlights: - Support for a new OPAL call on bare metal machines which gives us a true NMI (ie. is not masked by MSR[EE]=0) for debugging etc. - Support for Power9 DD2 in the CXL driver. - Improvements to machine check handling so that uncorrectable errors can be reported into the generic memory_failure() machinery. - Some fixes and improvements for VPHN, which is used under PowerVM to notify the Linux partition of topology changes. - Plumbing to enable TM (transactional memory) without suspend on some Power9 processors (PPC_FEATURE2_HTM_NO_SUSPEND). - Support for emulating vector loads form cache-inhibited memory, on some Power9 revisions. - Disable the fast-endian switch "syscall" by default (behind a CONFIG), we believe it has never had any users. - A major rework of the API drivers use when initiating and waiting for long running operations performed by OPAL firmware, and changes to the powernv_flash driver to use the new API. - Several fixes for the handling of FP/VMX/VSX while processes are using transactional memory. - Optimisations of TLB range flushes when using the radix MMU on Power9. - Improvements to the VAS facility used to access coprocessors on Power9, and related improvements to the way the NX crypto driver handles requests. - Implementation of PMEM_API and UACCESS_FLUSHCACHE for 64-bit.

2017-11-15kmemcheck: remove annotationsLevin, Alexander (Sasha Levin)1-2/+0
Patch series "kmemcheck: kill kmemcheck", v2. As discussed at LSF/MM, kill kmemcheck. KASan is a replacement that is able to work without the limitation of kmemcheck (single CPU, slow). KASan is already upstream. We are also not aware of any users of kmemcheck (or users who don't consider KASan as a suitable replacement). The only objection was that since KASAN wasn't supported by all GCC versions provided by distros at that time we should hold off for 2 years, and try again. Now that 2 years have passed, and all distros provide gcc that supports KASAN, kill kmemcheck again for the very same reasons. This patch (of 4): Remove kmemcheck annotations, and calls to kmemcheck from the kernel.
