* MAINTAINERS: Saying goodbye to David BrownellGrant Likely2011-06-072-10/+12
| | | | | | | | | | | | | | | We had to say goodbye when David passed away recently. David had a huge impact on our community, both personally in the lives of the people he worked with, and technically in the design and maintenance of several subsystems. He is greatly missed. He also leaves behind a number of much loved subsystems now orphaned. This patch updates the MAINTAINERS file for the areas that David was responsible for and adds an entry for him to the CREDITS file.

* | MN10300: die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs()David Howells2011-06-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs() to indicate that it wants to probe a kernel address. Instead it should use probe_kernel_read(). This fixes the problem of gdb seeing SIGILL rather than SIGTRAP when hitting the KGDB special breakpoint upon SysRq+g being seen. The problem was that die_if_no_fixup() was failing to read the opcode of the instruction that caused the exception, and thus not fixing up the exception. This caused gdb to get a S04 response to the $? request in its remote protocol rather than S05 - which would then cause it to continue with $C04 rather than $c in an attempt to pass the signal onto the inferior process. The kernel, however, does not support $Cnn, and so objects by returning an E22 response, indicating an error. gdb does not expect this and prints: warning: Remote failure reply: E22 and then returns to the gdb command prompt unable to continue.

* | MN10300: Fix one of the kernel debugger cacheflush variantsDavid Howells2011-06-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the kernel debugger cacheflush variants escaped proper testing. Two of the labels are wrong, being derived from the code that was copied to construct the variant. The first label results in the following assembler message: AS arch/mn10300/mm/cache-dbg-flush-by-reg.o arch/mn10300/mm/cache-dbg-flush-by-reg.S: Assembler messages: arch/mn10300/mm/cache-dbg-flush-by-reg.S:123: Error: symbol `debugger_local_cache_flushinv_no_dcache' is already defined And the second label results in the following linker message: arch/mn10300/mm/built-in.o:(.text+0x1d39): undefined reference to `mn10300_local_icache_inv_range_reg_end' arch/mn10300/mm/built-in.o:(.text+0x1d39): relocation truncated to fit: R_MN10300_PCREL16 against undefined symbol `mn10300_local_icache_inv_range_reg_end' To test this file the following configuration pieces must be set: CONFIG_AM34=y CONFIG_MN10300_CACHE_WBACK=y CONFIG_MN10300_DEBUGGER_CACHE_FLUSH_BY_REG=y CONFIG_MN10300_CACHE_MANAGE_BY_REG=y CONFIG_AM34_HAS_CACHE_SNOOP=n Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Some of the bits are reserved by the hardware and should not be changed by qdio. Currently all four values are overwritten since the SBAL entry flag is defined as an u32.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 9ff4cfb3fcfd48b49fdd9be7381b3be340853aa4 ([S390] kvm-390: Let kernel exit SIE instruction on work) fixed a problem of commit commit cd3b70f5d4d82f85d1e1d6e822f38ae098cf7c72 ([S390] virtualization aware cpu measurement) but uncovered another one. If a kvm guest accesses guest real memory that doesnt exist, the page fault handler calls the sie hook, which then rewrites the return psw from sie_inst to either sie_exit or sie_reenter. On return, the page fault handler will then detect the wrong access as a kernel fault causing a kernel oops in sie_reenter or sie_exit. We have to add these two addresses to the exception table to allow graceful exits.

The symptom is that all nodes but one will hang, waiting for a particular glock. All the holder records will have the "W" (Waiting) bit set. The other node will typically have the glock stuck in Exclusive mode (EX) with no holder records, but the dinode will be cached. In other words, an entry with "I:" will appear in the glock dump for that glock, but nothing else. The race has to do with the glock "Pending Demote" bit, which can be set, then immediately reset, thus losing the fact that another node needs the glock. The sequence of events is: 1. Something schedules the glock workqueue (e.g. glock request from fs) 2. The glock workqueue gets to the point between the test of the reply pending bit and the spin lock: if (test_and_clear_bit(GLF_REPLY_PENDING, &gl->gl_flags)) { finish_xmote(gl, gl->gl_reply); drop_ref = 1; } down_read(&gfs2_umount_flush_sem); <---- i.e. here spin_lock(&gl->gl_spin); 3. In comes (a) the reply to our EX lock request setting GLF_REPLY_PENDING and (b) the demote request which sets GLF_PENDING_DEMOTE 4. The following test is executed: if (test_and_clear_bit(GLF_PENDING_DEMOTE, &gl->gl_flags) && gl->gl_state != LM_ST_UNLOCKED && gl->gl_demote_state != LM_ST_EXCLUSIVE) { This resets the pending demote flag, and gl->gl_demote_state is not equal to exclusive, however because the reply from the dlm arrived after we checked for the GLF_REPLY_PENDING flag, gl->gl_state is still equal to unlocked, so although we reset the GLF_PENDING_DEMOTE flag, we didn't then set the GLF_DEMOTE flag or reinstate the GLF_PENDING_DEMOTE_FLAG. The patch closes the timing window by only transitioning the "Pending demote" bit to the "demote" flag once we know the other conditions (not unlocked and not exclusive) are met.
