- Fix mmc_test_alloc_mem. - Use nr_free_buffer_pages() instead of sysinfo.totalram to determine total lowmem pages. - Change variables containing memory sizes to unsigned long. - Limit maximum test area size to 128MiB because that is the maximum MMC high capacity erase size (the maxmium SD allocation unit size is just 4MiB) Signed-off-by: NAdrian Hunter <adrian.hunter@nokia.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

mmc_test provides tests aimed at testing SD/MMC hosts. This patch adds performance tests. It is advantageous to have performance tests in a kernel module like mmc_test for the following reasons: - transfer times can be measured very accurately - arbitrarily large transfers are possible - the effect of contiguous vs scattered pages can be determined The new tests are: 23. Best-case read performance 24. Best-case write performance 25. Best-case read performance into scattered pages 26. Best-case write performance from scattered pages 27. Single read performance by transfer size 28. Single write performance by transfer size 29. Single trim performance by transfer size 30. Consecutive read performance by transfer size 31. Consecutive write performance by transfer size 32. Consecutive trim performance by transfer size Signed-off-by: NAdrian Hunter <adrian.hunter@nokia.com> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

This patch fixes a bug in the multiblock write tests where the written data is read back for verifying one block at a time. The tests in mmc_test assumes that all cards are byte addressable. This will cause the multi block write tests to fail, leading the user of the mmc_test driver thinking there is something wrong with the sdhci driver they are testing. The start address for the block is calculated as: blocknum * 512. For block addressable cards the blocknum alone should be used.

The mutex mmc_test_lock is initialized at every time mmc_test device is probed. Probing another mmc_test device may break the mutex, if the probe function is called while the mutex is locked.

Add a couple of tests to make sure the host driver handles highmem memory pages properly. Unfortunately there is no way to guarantee an allocation below 4 GB in i386, so it might give you addresses that are out of reach for the hardware (OTOH, so will any other highmem allocation in the kernel).
