From cd03281d3c2c168f32e42783ee78995772a1763a Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Thu, 19 Feb 2015 19:14:02 +0530 Subject: sync_file_range: fix standard UCLIBC_SYSCALL_ALIGN_64BIT handling Currently UCLIBC_SYSCALL_ALIGN_64BIT is not explicitly handled. Fix that and make sure the special handling is done for powerpc/xtensa which use UCLIBC_SYSCALL_ALIGN_64BIT but don't use hole punched syscall handler in kernel.
