New Revision: 313343
URL: https://svnweb.freebsd.org/changeset/base/313343

Log:
  sys/arm/arm/identcpu-v4.c: fix identify_arm_cpu()
  
  identify_arm_cpu() in sys/arm/arm/identcpu-v4.c incorrectly uses a
  u_int8_t variable to store the result of cpu_get_control().
  It should really use a u_int variable, the same way as done for cpu_ident()
  in the same function, as both cpuid and control registers are 32-bit..
  This issue causes users of identcpu-v4 to incorrectly report things such as
  icache status (bit 12 in cpu control register) and basically anything
  defined in bits above bit 7 :-)
