[PATCH 0/8] mm: add page cache limit and reclaim feature

When system(e.g. smart phone) running for a long time, the cache often takes a large memory, maybe the free memory is less than 50M, then OOM will happen if APP allocate a large order pages suddenly and memory reclaim too slowly. Use "echo 3 > /proc/sys/vm/drop_caches" will drop the whole cache,

[PATCH V2] ARM: STi: DT: Properly define sti-ethclk & stmmaceth for stih415/6

This patch fixes two problems: - 1) The device tree isn't currently providing sti-ethclk which is required by the dwmac glue code to correctly configure the ethernet PHY clock speed. This means depending on what the bootloader/jtag has configured this clock to, and what switch/hub the board is

[PATCH 2/2] fs/seq_file: fallback to vmalloc allocation

[PATCH 1/2] proc/stat: convert to single_open_size()

Use seq_file's single_open_size() to preallocate a buffer that is large enough to hold the whole output, instead of open coding it. Also calculate the requested size using the number of online cpus instead of possible cpus, since the size of the output only depends on the number of online cpus.
