[PATCH] lib/string: Pass the input gfp flags to kmalloc

Pass the user sent gfp flags to kmalloc() calls. This helps calling the functions in user desired contexts. Signed-off-by: Sharat Masetty --- lib/string_helpers.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/string_helpers.c b/lib/string_helpers.c index 29c490e

[PATCH 3/3] drm/msm: Optimize adreno_show_object()

depends on the size of the data captured by the driver. This is certainly not desirable and does not scale well with large captures. This patch encodes the buffer only once in the read path. With this there is an immediate >10X speed improvement in crashstate save time. Signed-off-by: Sharat Mase
