2019-10-30	powerpc/tools: Don't quote $objdump in scripts	Michael Ellerman	1	-2/+2
	Some of our scripts are passed $objdump and then call it as "$objdump". This doesn't work if it contains spaces because we're using ccache, for example you get errors such as: ./arch/powerpc/tools/relocs_check.sh: line 48: ccache ppc64le-objdump: No such file or directory ./arch/powerpc/tools/unrel_branch_check.sh: line 26: ccache ppc64le-objdump: No such file or directory Fix it by not quoting the string when we expand it, allowing the shell to do the right thing for us.

2017-05-30	powerpc/64s: Tool to flag direct branches from unrelocated interrupt vectors	Nicholas Piggin	1	-0/+57
	Direct banches from code below __end_interrupts to code above __end_interrupts when built with CONFIG_RELOCATABLE are disallowed because they will break when the kernel is not located at 0. Sample output: WARNING: Unrelocated relative branches c000000000000118 bl-> 0xc000000000038fb8 <pnv_restore_hyp_resource> c00000000000013c b-> 0xc0000000001068a4 <kvm_start_guest> c000000000000148 b-> 0xc00000000003919c <pnv_wakeup_loss> c00000000000014c b-> 0xc00000000003923c <pnv_wakeup_noloss> c0000000000005a4 b-> 0xc000000000106ffc <kvmppc_interrupt_hv> c000000000001af0 b-> 0xc000000000106ffc <kvmppc_interrupt_hv> c000000000001b24 b-> 0xc000000000106ffc <kvmppc_interrupt_hv> c000000000001b58 b-> 0xc000000000106ffc <kvmppc_interrupt_hv> Signed-off-by: Balbir Singh <bsingharora@gmail.com> Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
