This config exists entirely to hide the cpufreq menu from the kernel configuration unless a platform has selected it. Nothing is actually built if this config is 'Y' and it just leads to more patches that add a select under a platform Kconfig so that some other CPUfreq option can be chosen. Let's remove the option so that we can always enable CPUfreq drivers on unicore32 platforms.

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.

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.

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.

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: NCatalin Marinas <catalin.marinas@arm.com>

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).

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.

The value of ESR has been stored into x1, and should be directly pass to do_sp_pc_abort function, "MOV x1, x25" is an extra operation and do_sp_pc_abort will get the wrong value of ESR.

Commit aa8532c3 (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.
