[PATCH v2] ARC: Use 40-bit physical page mask for PAE

by Vladimir Isaev

32-bit PAGE_MASK can not be used as a mask for physical addresses when PAE is enabled. PAGE_MASK_PHYS must be used for physical addresses instead of PAGE_MASK. Without this, init gets SIGSEGV if pte_modify was called: potentially unexpected fatal signal 11.

[PATCH v1 2/2] mmc: cavium: Remove redundant if-statement checkup

by Bean Huo

From: Bean Huo <beanhuo(a)micron.com> Currently, we have two ways to issue multiple-block read/write the command to the eMMC. One is by normal IO request path fs->block->mmc. Another one is that we can issue multiple-block read/write through MMC ioctl interface. For the first path, mrq->stop, and mrq->stop->opcode will be initialized in mmc_blk_data_prep(). However, for the second IO path, mrq->stop is not initialized since it is a pre-defined multiple blocks read/write. Meanwhile, if it is open-ended multiple block read/write command, STOP_TRANSMISSION CMD12 will be issued later in mmc_blk_issue_drv_op(), since it is MMC_IOC_MULTI_CMD. So, delete these if-statement checkups, let these kinds of multiple-block read/write request go.

[PATCH] xen/gntdev: fix gntdev_mmap() error exit path

by Juergen Gross

Commit d3eeb1d77c5d0af ("xen/gntdev: use mmu_interval_notifier_insert") introduced an error in gntdev_mmap(): in case the call of mmu_interval_notifier_insert_locked() fails the exit path should not call mmu_interval_notifier_remove(), as this might result in NULL dereferences. One reason for failure is e.g. a signal pending for the running process.

[PATCH v3 1/7] mtd: rawnand: cs553x: Fix external use of SW Hamming ECC helper

by Miquel Raynal

Since the Hamming software ECC engine has been updated to become a proper and independent ECC engine, it is now mandatory to either initialize the engine before using any one of his functions or use one of the bare helpers which only perform the calculations. As there is no actual need for a proper ECC initialization, let's just use the bare helper instead of the rawnand one.
