2015-06-21T06:28:26Z

Add kern.racct.enable tunable and RACCT_DISABLED config option. The point of this is to be able to add RACCT (with RACCT_DISABLED) to GENERIC, to avoid having to rebuild the kernel to use rctl(8). MFC r282901: Build GENERIC with RACCT/RCTL support by default. Note that it still needs to be enabled by adding "kern.racct.enable=1" to /boot/loader.conf. Note those two are MFC-ed together, because the latter one changes the name of RACCT_DISABLED option to RACCT_DEFAULT_TO_DISABLED. Should have committed the renaming separately...

MFamd64: Use initializecpu() to set various model-specific registers on AP startup and AP resume (it was already used for BSP startup and BSP resume).

- Remove spaces from boot messages when we print the CPU ID/Family/Stepping - Move prototypes for various functions into out of C files and into . - Reduce diffs between i386 and amd64 initcpu.c and identcpu.c files. - Move blacklists of broken TSCs out of the printcpuinfo() function and into the TSC probe routine. - Merge the amd64 and i386 identcpu.c into a single x86 implementation.

Don't waste a page of KVA for the boot-time memory test on x86. For amd64, reuse the first page of the crashdumpmap as CMAP1/CADDR1. For i386, remove CMAP1/CADDR1 entirely and reuse CMAP3/CADDR3 for the memory test.

MFC r258135: x86: Allow users to change PSL_RF via ptrace(PT_SETREGS...)

2013-11-25T15:58:48Z

Debuggers may need to change PSL_RF. Note that tf_eflags is already stored in the signal context during signal handling and PSL_RF previously could be modified via sigreturn, so this change should not provide any new ability to userspace.
