h8300: Hardcode symbol prefixes in asm sources
Commit e1b5bb6d1236d4ad2084c53aa83dde7cdf6f8eea ("consolidate cond_syscall
and SYSCALL_ALIAS declarations") broke the h8300 build because it removed
the duplicate SYMBOL_NAME() macro from arch/h8300/include/asm/linkage.h,
and all the h8300 asm files include <asm/linkage.h> instead of
<linux/linkage.h>:

Commit 126de6b20bfb82cc19012d5048f11f339ae5a021 ("linkage.h: fix build
breakage due to symbol prefix handling") broke it even more, by removing
SYMBOL_NAME() and replacing it by __SYMBOL_NAME().
Commit f8ce1faf55955de62e0a12e330c6d9a526071f65 ("Merge tag
'modules-next-for-linus' of
git://git.kernel.org/pub/scm/linuxkernel/git/rusty/linux")
also removed __SYMBOL_NAME(), hidden in a merge conflict resolution.
Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
assembler sources by hardcoding the underscore symbol prefix, like other
architectures (blackfin/metag) do.
This allows to kill SYMBOL_NAME_LABEL(). Now <asm/linkage.h> becomes empty,
and h8300 can be switched to asm-generic/linkage.h.

h8300: Hardcode symbol prefixes in asm sources
Commit e1b5bb6d1236d4ad2084c53aa83dde7cdf6f8eea ("consolidate cond_syscall
and SYSCALL_ALIAS declarations") broke the h8300 build because it removed
the duplicate SYMBOL_NAME() macro from arch/h8300/include/asm/linkage.h,
and all the h8300 asm files include <asm/linkage.h> instead of
<linux/linkage.h>:

Commit 126de6b20bfb82cc19012d5048f11f339ae5a021 ("linkage.h: fix build
breakage due to symbol prefix handling") broke it even more, by removing
SYMBOL_NAME() and replacing it by __SYMBOL_NAME().
Commit f8ce1faf55955de62e0a12e330c6d9a526071f65 ("Merge tag
'modules-next-for-linus' of
git://git.kernel.org/pub/scm/linuxkernel/git/rusty/linux")
also removed __SYMBOL_NAME(), hidden in a merge conflict resolution.
Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
assembler sources by hardcoding the underscore symbol prefix, like other
architectures (blackfin/metag) do.
This allows to kill SYMBOL_NAME_LABEL(). Now <asm/linkage.h> becomes empty,
and h8300 can be switched to asm-generic/linkage.h.

h8300: Hardcode symbol prefixes in asm sources
Commit e1b5bb6d1236d4ad2084c53aa83dde7cdf6f8eea ("consolidate cond_syscall
and SYSCALL_ALIAS declarations") broke the h8300 build because it removed
the duplicate SYMBOL_NAME() macro from arch/h8300/include/asm/linkage.h,
and all the h8300 asm files include <asm/linkage.h> instead of
<linux/linkage.h>:

Commit 126de6b20bfb82cc19012d5048f11f339ae5a021 ("linkage.h: fix build
breakage due to symbol prefix handling") broke it even more, by removing
SYMBOL_NAME() and replacing it by __SYMBOL_NAME().
Commit f8ce1faf55955de62e0a12e330c6d9a526071f65 ("Merge tag
'modules-next-for-linus' of
git://git.kernel.org/pub/scm/linuxkernel/git/rusty/linux")
also removed __SYMBOL_NAME(), hidden in a merge conflict resolution.
Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
assembler sources by hardcoding the underscore symbol prefix, like other
architectures (blackfin/metag) do.
This allows to kill SYMBOL_NAME_LABEL(). Now <asm/linkage.h> becomes empty,
and h8300 can be switched to asm-generic/linkage.h.

h8300: Hardcode symbol prefixes in asm sources
Commit e1b5bb6d1236d4ad2084c53aa83dde7cdf6f8eea ("consolidate cond_syscall
and SYSCALL_ALIAS declarations") broke the h8300 build because it removed
the duplicate SYMBOL_NAME() macro from arch/h8300/include/asm/linkage.h,
and all the h8300 asm files include <asm/linkage.h> instead of
<linux/linkage.h>:
arch/h8300/kernel/entry.S: Assembler messages:

Commit 126de6b20bfb82cc19012d5048f11f339ae5a021 ("linkage.h: fix build
breakage due to symbol prefix handling") broke it even more, by removing
SYMBOL_NAME() and replacing it by __SYMBOL_NAME().
Commit f8ce1faf55955de62e0a12e330c6d9a526071f65 ("Merge tag
'modules-next-for-linus' of
git://git.kernel.org/pub/scm/linuxkernel/git/rusty/linux")
also removed __SYMBOL_NAME(), hidden in a merge conflict resolution.
Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
assembler sources by hardcoding the underscore symbol prefix, like other
architectures (blackfin/metag) do.
This allows to kill SYMBOL_NAME_LABEL(). Now <asm/linkage.h> becomes empty,
and h8300 can be switched to asm-generic/linkage.h.

Commit 126de6b20bfb82cc19012d5048f11f339ae5a021 ("linkage.h: fix build
breakage due to symbol prefix handling") broke it even more, by removing
SYMBOL_NAME() and replacing it by __SYMBOL_NAME().
Commit f8ce1faf55955de62e0a12e330c6d9a526071f65 ("Merge tag
'modules-next-for-linus' of
git://git.kernel.org/pub/scm/linuxkernel/git/rusty/linux")
also removed __SYMBOL_NAME(), hidden in a merge conflict resolution.
Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
assembler sources by hardcoding the underscore symbol prefix, like other
architectures (blackfin/metag) do.
This allows to kill SYMBOL_NAME_LABEL(). Now <asm/linkage.h> becomes empty,
and h8300 can be switched to asm-generic/linkage.h.

h8300: Hardcode symbol prefixes in asm sources
Commit e1b5bb6d1236d4ad2084c53aa83dde7cdf6f8eea ("consolidate cond_syscall
and SYSCALL_ALIAS declarations") broke the h8300 build because it removed
the duplicate SYMBOL_NAME() macro from arch/h8300/include/asm/linkage.h,
and all the h8300 asm files include <asm/linkage.h> instead of
<linux/linkage.h>:

Commit e1b5bb6d1236d4ad2084c53aa83dde7cdf6f8eea ("consolidate cond_syscall
and SYSCALL_ALIAS declarations") broke the h8300 build because it removed
the duplicate SYMBOL_NAME() macro from arch/h8300/include/asm/linkage.h,
and all the h8300 asm files include <asm/linkage.h> instead of
<linux/linkage.h>:

Commit 126de6b20bfb82cc19012d5048f11f339ae5a021 ("linkage.h: fix build
breakage due to symbol prefix handling") broke it even more, by removing
SYMBOL_NAME() and replacing it by __SYMBOL_NAME().
Commit f8ce1faf55955de62e0a12e330c6d9a526071f65 ("Merge tag
'modules-next-for-linus' of
git://git.kernel.org/pub/scm/linuxkernel/git/rusty/linux")
also removed __SYMBOL_NAME(), hidden in a merge conflict resolution.
Hence, replace the use of SYMBOL_NAME() and SYMBOL_NAME_LABEL() in h8300
assembler sources by hardcoding the underscore symbol prefix, like other
architectures (blackfin/metag) do.
This allows to kill SYMBOL_NAME_LABEL(). Now <asm/linkage.h> becomes empty,
and h8300 can be switched to asm-generic/linkage.h.
