2014-06-18arm64: ptrace: fix empty registers set in prstatus of aarch32 process coreVictor Kamensky
Currently core file of aarch32 process prstatus note has empty registers set. As result aarch32 core files create by V8 kernel are not very useful. It happens because compat_gpr_get and compat_gpr_set functions can copy registers values to/from either kbuf or ubuf. ELF core file collection function fill_thread_core_info calls compat_gpr_get with kbuf set and ubuf set to 0. But current compat_gpr_get and compat_gpr_set function handle copy to/from only ubuf case. Fix is to handle kbuf and ubuf as two separate cases in similar way as other functions like user_regset_copyout, user_regset_copyin do.

2014-06-18arm64: uid16: fix __kernel_old_{gid,uid}_t definitionsWill Deacon
Whilst native arm64 applications don't have the 16-bit UID/GID syscalls wired up, compat tasks can still access them. The 16-bit wrappers for these syscalls use __kernel_old_uid_t and __kernel_old_gid_t, which must be 16-bit data types to maintain compatibility with the 16-bit UIDs used by compat applications. This patch defines 16-bit __kernel_old_{gid,uid}_t types for arm64 instead of using the 32-bit types provided by asm-generic.

2014-06-18arm64: ptrace: change fs when passing kernel pointer to regset codeWill Deacon
Our compat PTRACE_POKEUSR implementation simply passes the user data to regset_copy_from_user after some simple range checking. Unfortunately, the data in question has already been copied to the kernel stack by this point, so the subsequent access_ok check fails and the ptrace request returns -EFAULT. This causes problems tracing fork() with older versions of strace. This patch briefly changes the fs to KERNEL_DS, so that the access_ok check passes even with a kernel address.

2014-06-18arm64: Limit the CMA buffer to 32-bit if ZONE_DMACatalin Marinas
When the CMA buffer is allocated, it is too early to know whether devices will require ZONE_DMA memory. This patch limits the CMA buffer to (DMA_BIT_MASK(32) + 1) if CONFIG_ZONE_DMA is enabled. In addition, it computes the dma_to_phys(DMA_BIT_MASK(32)) before the increment (no current functional change). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2014-06-18arm/ftrace: fix ftrace_return_addr() to ftrace_return_address()Steven Rostedt
The clean up of CALLER_ADDR*() functions required the archs to either use the default __builtin_return_address(X) (where X > 0) or override it with something the arch can use. To override it, the arch would define ftrace_return_address(x). The arm architecture requires this to be redefined but instead of defining ftrace_return_address(x) it defined ftrace_return_addr(x).

2014-06-18arm64: add ARCH_HAS_OPP to allow enabling OPP librarySudeep Holla
The Operating Performance Point (OPP) Layer library is a generic library used by CPUFREQ and DEVFREQ. It can be enabled only on the platforms that specify ARCH_HAS_OPP option. This patch selects that option in order to allow ARM64 based platforms to use OPP library. Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2014-06-18xen/grant-table: fix suspend for non-PV guestsDavid Vrabel
Commit aa8532c32216ae07c3813b9aeb774517878a7573 (xen: refactor suspend pre/post hooks) broke resuming PVHVM (auto-translated physmap) guests. The gnttab_suspend() would clear the mapping for the grant table frames, but the ->unmap_frames() call is only applicable to PV guests.

2014-06-18x86/xen: no need to explicitly register an NMI callbackDavid Vrabel
Remove xen_enable_nmi() to fix a 64-bit guest crash when registering the NMI callback on Xen 3.1 and earlier. It's not needed since the NMI callback is set by a set_trap_table hypercall (in xen_load_idt() or xen_write_idt_entry()). It's also broken since it only set the current VCPU's callback.

2014-06-17epoll: fix use-after-free in eventpoll_release_fileKonstantin Khlebnikov
This fixes use-after-free of epi->fllink.next inside list loop macro. This loop actually releases elements in the body. The list is rcu-protected but here we cannot hold rcu_read_lock because we need to lock mutex inside. The obvious solution is to use list_for_each_entry_safe(). RCU-ness isn't essential because nobody can change this list under us, it's final fput for this file.

2014-06-16Revert "offb: Add palette hack for little endian"Benjamin Herrenschmidt
This reverts commit e1edf18b20076da83dd231dbd2146cbbc31c0b14. This patch was a misguided attempt at fixing offb for LE ppc64 kernels on BE qemu but is just wrong ... it breaks real LE/LE setups, LE with real HW, and existing mixed endian systems that did the fight thing with the appropriate device-tree property. Bad reviewing on my part, sorry. The right fix is to either make qemu change its endian when the guest changes endian (working on that) or to use the existing foreign endian support.
