  You are right.

  I also don't really care...

   Here I completely agree, I forgot that there were
lowercase g and z packets.

  My idea was to get rid of all issues so that I could mark that
rule as a regression, and that it would thus get a much greater
impact if new code would use such mixed case function names.
  
  This way, we could either decide that the mixed case is not
necessary and lowercase the function name, or add an ARI comment to accept
that exception.

  I would tend to agree that adding an ARI comment is probably justified on
most of these 18 functions.
  The only ones I am not sure about are:
  - splay_compare_CORE_ADDR_ptr in addrmap.c
there are numerous other functions refereeing to CORE_ADDR type without
using uppercase:
$ grep "^[a-z_0-9]*core_addr" *
arch-utils.c:core_addr_lessthan (CORE_ADDR lhs, CORE_ADDR rhs)
arch-utils.c:core_addr_greaterthan (CORE_ADDR lhs, CORE_ADDR rhs)
arch-utils.c:core_addr_identity (struct gdbarch *gdbarch, CORE_ADDR addr)
proc-service.c:ps_addr_to_core_addr (psaddr_t addr)
proc-service.c:core_addr_to_ps_addr (CORE_ADDR addr)
ui-out.c:ui_out_field_core_addr (struct ui_out *uiout,
utils.c:core_addr_to_string (const CORE_ADDR addr)
utils.c:core_addr_to_string_nz (const CORE_ADDR addr)
utils.c:string_to_core_addr (const char *my_string)
  
  So I would like to eliminate that one.

  - the other two are
proc_get_LDT_entry and procfs_find_LDT_entry in procfs.c

these two functions are only called by 
ps_lgetLDT inside sol-thread.c, which is, according to the comment
required by libthread_db solaris library. 
  But I do not know if this also justifies propagating the uppercase use
to the called functions in procfs.c

  Please tell me how I should proceed.
