vmlinux.lds.h: catch .bss..L* sections into BSS")
[ Upstream commit 1a7b7326d587c9a5e8ff067e70d6aaf0333f4bb3 ]
Commit 9a427556fb8e ("vmlinux.lds.h: catch compound literals into
data and BSS") added catches for .data..L* and .rodata..L* but missed
.bss..L*
Since commit 5431fdd2c181 ("ptrace: Convert ptrace_attach() to use
lock guards") the following appears at build:
LD .tmp_vmlinux.kallsyms1
powerpc64-linux-ld: warning: orphan section `.bss..Lubsan_data33' from `kernel/ptrace.o' being placed in section `.bss..Lubsan_data33'
NM .tmp_vmlinux.kallsyms1.syms
KSYMS .tmp_vmlinux.kallsyms1.S
AS .tmp_vmlinux.kallsyms1.S
LD .tmp_vmlinux.kallsyms2
powerpc64-linux-ld: warning: orphan section `.bss..Lubsan_data33' from `kernel/ptrace.o' being placed in section `.bss..Lubsan_data33'
NM .tmp_vmlinux.kallsyms2.syms
KSYMS .tmp_vmlinux.kallsyms2.S
AS .tmp_vmlinux.kallsyms2.S
LD vmlinux
powerpc64-linux-ld: warning: orphan section `.bss..Lubsan_data33' from `kernel/ptrace.o' being placed in section `.bss..Lubsan_data33'
Lets add .bss..L* to BSS_MAIN macro to catch those sections into BSS.
