OVERO/DUOVERO/PEPPER aren't tested.
PR/52010: Regression: Gumstix Verdex is hanging in enabling cache + KASSERT ram_size
to read-only and vice versa:
- Add an internal flag IMNT_WANTRDONLY.
- Set either IMNT_WANTRDWR or IMNT_WANTRDONLY if going from or to read-only.
- After successfull call to VFS_MOUNT() set or clear MNT_RDONLY.
Adapt tmpfs and rumpfs to the new protocol. Other file systems will be
updated when they get the IMNT_CAN_RWTORO property.
Welcome to 7.99.64
Added entries:
ptrace(2): Add new API replacing PT_WATCHPOINT for Debug Registers:
PT_GETDBREGS and PT_SETDBREGS
siginfo(2): Add new si_code values for SIGTRAP: TRAP_SCE and TRAP_SCX

Mark this test broken with kern/52012 as the tracee does not stop on syscall
entry. Check for siginfo(2) in syscall1 and unveil two new bugs.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia
discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST.
Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid
before 1979, to agree with tables compiled by Pere Planesas of the
National Astronomical Observatory of Spain. As a side effect,
this changes some time stamps for Africa/Ceuta before 1929, which
are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as
part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the
abbreviation "AST", the abbreviation commonly used at the time
(Atlantic Standard Time had not been standardized yet). Use "AWT"
and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau
before 1999 and Taiwan before 1938, and use "JST" instead of the
invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward',
since Johnston is now uninhabited.
put back the stwcx. instruction to clear the reservation.
we used to have this in the old cpu_switch() until it was
if-0'd in 2003 and removed completely in 2007.
this fixes hangs I've seen where a softint thread is
blocked waiting for a mutex that is not held.
this should also fix PR 44387.
