Hi all,

The following commits are also in the risc-v-fixes tree as different
commits (but the same patches):

  aad60bdd0b5a6 ("riscv: Fix fast_unaligned_access_speed_key not getting initialized")

This, and the manual merge issues mentioned earlier, were caused when I 
moved some patches out of the fixes branch into for-next, but didn't 
update the fixes branch on k.org.  Should be fixed now; sorry for the 
noise.

Each of these commits (separately) is a duplicate of a commit in Linus's
tree:

Sorry, but I'm lost here -- I'm not sure if I've managed to screw up git 
again?  If it helps, I'm not seeing the same commits here:

        riscv: Remove duplicate objcopy flag
    
        There are two duplicate `-O binary` flags when objcopying from vmlinux
        to Image/xipImage.
    
        RISC-V set `-O binary` flag in both OBJCOPYFLAGS in the top-level riscv
        Makefile and OBJCOPYFLAGS_* in the boot/Makefile, and the objcopy cmd
        in Kbuild would join them together.
    
        The `-O binary` flag is only needed for objcopying Image, so remove the
        OBJCOPYFLAGS in the top-level riscv Makefile.

        riscv: kexec: Align the kexeced kernel entry
    
        The current riscv boot protocol requires 2MB alignment for RV64
        and 4MB alignment for RV32.
    
        In KEXEC_FILE path, the elf_find_pbase() function should align
        the kexeced kernel entry according to the requirement, otherwise
        the kexeced kernel would silently BUG at the setup_vm().

Hi all,

The following commits are also in Linus Torvalds' tree as different
commits (but the same patches):

  767423658d53 ("riscv: kexec: Align the kexeced kernel entry")
  fe2ed36d419f ("riscv: Remove duplicate objcopy flag")
