      bloat-o-meter: ignore __addressable_ symbols · e0b2475a
      Rasmus Villemoes authored 
      Since __LINE__ is part of the symbol created by __ADDRESSABLE, almost
any change causes those symbols to disappear and get reincarnated, e.g.

add/remove: 4/4 grow/shrink: 0/3 up/down: 32/-171 (-139)
Function                                     old     new   delta

They're small and in .discard, so ignore them, leading to more useful

add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-139 (-139)

      syscalls/core, syscalls/x86: Clean up compat syscall stub naming convention · 5ac9efa3
      Dominik Brodowski authored 
      
Tidy the naming convention for compat syscall subs. Hints which describe
the purpose of the stub go in front and receive a double underscore to
denote that they are generated on-the-fly by the COMPAT_SYSCALL_DEFINEx()
macro.

For the generic case, this means:

t            kernel_waitid	# common C function (see kernel/exit.c)

    __do_compat_sys_waitid	# inlined helper doing the actual work
				# (takes original parameters as declared)

T   __se_compat_sys_waitid	# sign-extending C function calling inlined
				# helper (takes parameters of type long,
				# casts them to unsigned long and then to
				# the declared type)

T        compat_sys_waitid      # alias to __se_compat_sys_waitid()
				# (taking parameters as declared), to
				# be included in syscall table

For x86, the naming is as follows:

t            kernel_waitid	# common C function (see kernel/exit.c)

    __do_compat_sys_waitid	# inlined helper doing the actual work
				# (takes original parameters as declared)

t   __se_compat_sys_waitid      # sign-extending C function calling inlined
				# helper (takes parameters of type long,
				# casts them to unsigned long and then to
				# the declared type)

T __ia32_compat_sys_waitid	# IA32_EMULATION 32-bit-ptregs -> C stub,
				# calls __se_compat_sys_waitid(); to be
				# included in syscall table

T  __x32_compat_sys_waitid	# x32 64-bit-ptregs -> C stub, calls
				# __se_compat_sys_waitid(); to be included
				# in syscall table

If only one of IA32_EMULATION and x32 is enabled, __se_compat_sys_waitid()
may be inlined into the stub __{ia32,x32}_compat_sys_waitid().

For the generic case, this means (0xffffffff prefix removed):

 810f08d0 t     kernel_waitid	# common C function (see kernel/exit.c)

 <inline>     __do_sys_waitid	# inlined helper doing the actual work
				# (takes original parameters as declared)

 810f1aa0 T        sys_waitid	# alias to __se_sys_waitid() (taking
				# parameters as declared), to be included
				# in syscall table

For x86, the naming is as follows:

 810efc70 t     kernel_waitid	# common C function (see kernel/exit.c)

 <inline>     __do_sys_waitid	# inlined helper doing the actual work
				# (takes original parameters as declared)

 810efd60 t   __se_sys_waitid	# sign-extending C function calling inlined
				# helper (takes parameters of type long;
				# casts them to the declared type)

 810f1140 T __ia32_sys_waitid	# IA32_EMULATION 32-bit-ptregs -> C stub,
				# calls __se_sys_waitid(); to be included
				# in syscall table

 810f1110 T        sys_waitid	# x86 64-bit-ptregs -> C stub, calls
				# __se_sys_waitid(); to be included in
				# syscall table

For x86, sys_waitid() will be re-named to __x64_sys_waitid in a follow-up
patch.

      fix bloat-o-meter for ppc64 · 8998979c
      Nathan Lynch authored 
      
bloat-o-meter assumes that a '.' anywhere in a symbol's name means that it
is static and prepends 'static.' to the first part of the symbol name,
discarding the portion of the name that follows the '.'.  However, the
names of function entry points begin with '.' in the ppc64 ABI.  This
causes all function text size changes to be accounted to a single 'static.'
entry in the output when comparing ppc64 kernels.

Change getsizes() to ignore the first character of the symbol name when
searching for '.'.

      [PATCH] tiny: Add bloat-o-meter to scripts · d960600d
      Matt Mackall authored 
      
This is a rewrite of Andi Kleen's bloat-o-meter with sorting and reporting of
gainers/decliners.  Sample output:

add/remove: 0/8 grow/shrink: 2/0 up/down: 88/-4424 (-4336)
function                                     old     new   delta
__copy_to_user_ll                             59     103     +44
__copy_from_user_ll                           59     103     +44
fill_note                                     32       -     -32
maydump                                       58       -     -58
dump_seek                                     67       -     -67
writenote                                    180       -    -180
elf_dump_thread_status                       274       -    -274
fill_psinfo                                  308       -    -308
fill_prstatus                                466       -    -466
elf_core_dump                               3039       -   -3039

The summary line says:
 no functions added, 8 removed
 two functions grew, none shrunk
 we gained 88 bytes and lost 4424 (or -4336 net)
