Users may call FBIOPUT_VSCREENINFO ioctrl to do pan display. This ioctrl relies on fb_set_var() to do the job. fb_set_var() calls the custom fb_set_par() method and then calls the custom fb_pan_display() method. Before calling the custom fb_pan_display() method, info->var is already updated from the new *var in fb_set_var(). And, the custom fb_pan_display() method checks if xoffset and yoffset in info->var and the new *var are different before doing actual panning, which prevents the panning from happening within fb_set_var() context. This patch caches the current var info locally in mx3fb driver so that pan display with fb_set_var is supported. Signed-off-by:

Commit 9befe40f ("video: backlight: support s6e8ax0 panel driver based on MIPI DSI") added s6e8ax0.h, but no file includes it. That's probably a good thing, because it declares an extern void function that is defined static int in s6e8ax0.c. Besides, that function is also wrapped in the module_init() macro, which should do everything needed to make that function available to the code outside of s6e8ax0.c. This header can safely be removed. Signed-off-by:

The definition of 32-bit values in the 64-bit tilegx architecture is that they should be sign-extended regardless of whether they are considered signed or unsigned by the compiler. Accordingly, we need to use an "ld4s" rather than "ld4u" to load and sign-extend for get_user(). This fixes glibc bug 14238 (see http://sourceware.org/bugzilla), introduced during the 3.5 merge window. Signed-off-by:

Minchan Kim reports that when a system has many swap areas, and tmpfs swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read back the page cannot locate it, and the read fails with -ENOMEM. Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry( swp_entry_to_pte()) technique for determining maximum usable swap offset, without stopping to realize that that actually depends upon the pte swap encoding shifting swap offset to the higher bits and truncating it there. Whereas our radix_tree swap encoding leaves offset in the lower bits: it's swap "type" (that is, index of swap area) that was truncated. Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header(). This does not reduce the usable size of a swap area any further, it leaves it as claimed when making the original commit: no change from 3.0 on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB per swapfile on i386 with PAE. It's not a change I would have risked five years ago, but with x86_64 supported for ten years, I believe it's appropriate now. Hmm, and what if some architecture implements its swap pte with offset encoded below type? That would equally break the maximum usable swap offset check. Happily, they all follow the same tradition of encoding offset above type, but I'll prepare a check on that for next. Reported-and-Reviewed-and-Tested-by:
