x86, selftests: Add sigreturn selftest This is my sigreturn test, added mostly unchanged from its old home. It exercises the sigreturn(2) syscall, specifically focusing on its interactions with various IRET corner cases. It tests for correct behavior in several areas that were historically dangerously buggy. For example, it exercises espfix on kernels of both bitnesses under various conditions, and it contains testcases for several now-fixed bugs in IRET error handling. If you run it on older kernels without the fixes, your system will crash. It probably won't eat your data in the process. There is no released kernel on which the sigreturn_64 test will pass, but it passes on tip:x86/asm. I plan to switch to lib.mk for Linux 4.2. I'm not using the ksft_ helpers at all yet. I can do that later.

selftests/zram: Adding zram tests zram: Compressed RAM based block devices ---------------------------------------- The zram module creates RAM based block devices named /dev/zram<id> (<id> = 0, 1, ...). Pages written to these disks are compressed and stored in memory itself. These disks allow very fast I/O and compression provides good amounts of memory savings. Some of the usecases include /tmp storage, use as swap disks, various caches under /var and maybe many more :) Statistics for individual zram devices are exported through sysfs nodes at /sys/block/zram<id>/ This patch is to validate the zram functionality. Test interacts with block device /dev/zram<id> and sysfs nodes /sys/block/zram<id>/ zram.sh: sanity check of CONFIG_ZRAM and to run zram01 and zram02 tests zram01.sh: creates general purpose ram disks with different filesystems zram02.sh: creates block device for swap zram_lib.sh: create library with initialization/cleanup functions README: ZRAM introduction and Kconfig required.
