2010-08-05docbook: use IDs as filenames to support multiple booksJohannes Berg
I'm trying to generate a <set> of <book>s in docbook for wireless to link together all the cfg80211 and mac80211 documentation. However, docbook will generate "re01.html" anew for each book for the first <refentry>, presumably due to a bug in the stylesheets. An effective workaround is to use IDs for the filenames, which makes them more descriptive as well, e.g. API-enum-ieee80211-band.html.

Commit 5349ef3127c77075ff70b2014f17ae0fbcaaf199 (drm/fb: fix FBIOGET/PUT_VSCREENINFO pixel clock handling) changed the logic of when a pixclock was valid vs invalid.

2010-08-05gdbstub: do not directly use dbg_reg_def[] in gdb_cmd_reg_set()Jason Wessel
Presently the usable registers definitions on x86 are not contiguous for kgdb. The x86 kgdb uses a case statement for the sparse register accesses. The array which defines the registers (dbg_reg_def) should not be used directly in order to safely work with sparse register definitions. Specifically there was a problem when gdb accesses ORIG_AX, which is accessed only through the case statement. This patch encodes register memory using the size information provided from the debugger which avoids the need to look up the size of the register. The dbg_set_reg() function always further validates the inputs from the debugger. Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com>
2010-08-05gdbstub: Implement gdbserial 'p' and 'P' packetsJason Wessel
